**Welcome to DSF Sandbox Sessions!** Top tech talks and masterclasses from the best in the industry. Every month, and completely free. The catch? There isn’t one. Just a monthly dose of epic content to power up your data passion! **Event details** 📆 **Date:** Tuesday 14th April 2026 ⏰ **Time:** 6:00 – 9:30 PM BST 💡 **Topic:** **Signals, Systems, and Scams: Deconstructing the Future of Financial Intelligence** 🗣️ **Speakers:** Kristjan Erik Liive, Volodymyr Panov, Baran Koseoglu, Zoltan Szopory, Vera Shishkina, Aaron Wilson, Mohammed Topiwalla [Sign up for this event by clicking here!](https://datasciencefestival.com/session/wise-sandbox-session/) As global financial platforms evolve, the “Trust Gap” becomes an engineering challenge. Scaling a product to millions of users requires more than just better models—it requires a fundamental shift from manual heuristics to automated, high-fidelity intelligence. Join Wise for an exclusive Sandbox Session designed for senior data scientists and engineers. We’re moving beyond the basics of model training to explore the “Last Mile” of production ML: the infrastructure of compliance, the democratisation of optimization, and the transition to foundational representation learning. Through three practitioner-led deep dives and a collaborative product-data science panel, we will deconstruct how Wise builds resilient financial infrastructure where performance and safety are never a zero-sum game. What we’ll explore: • The GenAI Reality Check: Moving LLM automations from “cool demo” to “compliant production” in highly regulated spaces. • Decoupling Optimization: How we built “Threshold UI” to empower non-experts to tune model performance across hundreds of cohorts without a single code change. • Beyond Velocity: Replacing hand-crafted features with User Event Transformers to capture the deep behavioral context that traditional tabular data misses. • The Co-Design Philosophy: Why the future of fraud prevention isn’t just a better algorithm, but a tighter feedback loop between Product and Data Science. Food, drinks, and networking with fellow practitioners will follow throughout the evening. Check out the full session details below! **Please note: Due to high demand and limited capacity, tickets for this event will be allocated via a random ballot. Submitting an application does not guarantee entry. Successful applicants will be notified throughout March and early April. If you have not received confirmation by April 9th, this means your ballot application was not selected on this occasion.** **Talk 1: Evolution of GenAI: Building Compliant LLM Automations at Wise** **Speakers:** Kristjan Erik Liive, Senior Data Scientist & Volodymyr Panov, Senior Data Scientist. **Abstract:** Evolution of GenAI applications in servicing tasks at Wise. We will share examples, discuss architectures and challenges of building LLM-based automations in compliance-heavy space. We will also present our vision and key opportunity areas in further augmentation and automation. **Key takeaways:** Practical examples of scoping and implementing LLM-based solutions. **Talk 2: On the Threshold of Greatness: Democratizing Model Optimization at Wise** **Speakers:** Baran Köseoğlu, Lead Data Scientist & Zoltán Szopory, Staff Software Engineer. **Abstract:** This session will talk about machine learning model threshold optimization across hundreds of customer cohorts. Traditionally, optimizing these thresholds has been a complex, time-consuming task, often relegated to highly technical experts. At Wise, we faced the challenge of managing diverse customer segments, each with unique risk profiles and compliance mandates and as a solution we developed Threshold UI we will talk about more in the session. **Key takeaways:** Boost your machine learning model performance without changing any configuration in your training pipeline. **Talk 3: More Than Meets the Eye: Transforming User Events into Deep Context** **Speaker:** Vera Shishkina, Staff Data Scientist. **Abstract:** Moving from purely manual feature engineering to representation learning. This session covers the technical POC of a User Events Transformer – a foundational model designed to produce customer embeddings that augment traditional tabular features. We will discuss the proposed architecture, the challenges of building temporal data pipelines, and our vision for using these embeddings to boost performance in domains like scam prediction. **Key takeaways:** How learned embeddings provide deep context that traditional “velocity” features often miss. **Talk 4: Panel Discussion – Mind & Machine: How Product and DS Co-Design the Future of Trust** **Panellists:** Aaron Wilson, Fraud and Victim Prevention Product Lead & Mohammed Topiwalla, Fraud and Victim Prevention Data Science Lead. **Abstract:** Fireside chat to understand how DS and Product work hand in hand to keep wise safe. **Key takeaways:** How do you find the middle ground between business growth and risk precision? What is the future of DS in fraud prevention? **Schedule:** **6:00 PM** – Doors open – networking with food and refreshments **6:45 PM** – Intro **6:50 PM** – Talk 1 (20 minutes + 5 minute Q&A) **7:15 PM** – Talk 2 (20 minutes + 5 minute Q&A) **7:40 PM** – Comfort break **7:50 PM** – Talk 3 (20 minutes + 5 minute Q&A) **8:15 PM** – Talk 4 (30 minutes) **8:45 PM** – Networking with refreshments **9:30 PM** – Event close **Registering for the event:** Click the 'Sign up here!' button on the specific event page following the link below.

We're excited to be back and pleased to say this event is being sponsored by [pgMustard](https://pgmustard.com). On the talks front, we have **Anton Borisov and Vlad Bokov** from Fresha who will take us through how they recently upgraded their fleet with zero-downtime. We will then host our first ever debate, on a topic to be determined! WHERE Join us at **Doggett's Coat and Badge on 14 April from 18:30.** PROGRAM 18:30 Welcome 19:00 Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice (Anton Borisov and Vlad Bokov, Fresha) - abstract below 19:45 Sandwiches and bar snacks (paid for by our sponsor) 20:00 Debate — topic TBD ABSTRACT **Swapping the Elephant Without Breaking the Room: Zero-downtime Major PG upgrades in practice** Upgrading PostgreSQL across hundreds of production databases without downtime sounds impossible, especially when logical replication slots, Debezium CDC pipelines, and outbox event streams are in play. At Fresha, we faced exactly that: mission-critical workloads still on PostgreSQL 12, and no safe way to reach 17 without freezing the business. This talk walks through how we designed and automated a blue-green upgrade framework using logical decoding, controlled WAL overlap, and connector orchestration. We’ll dive into how Debezium connectors, replication origins, and PgBouncer pools were coordinated to guarantee continuity for both CDC and outbox topics, with rollback and dry-run modes built in. Attendees will learn practical techniques for: * Orchestrating zero-downtime Postgres major upgrades on RDS or self-managed clusters * Managing replication slots and Debezium connectors safely across clusters * Handling sequence alignment, WAL overlap, and connector state transitions * Designing reversible, testable database cutovers This is a practical session from real production experience: no magic tools, just PostgreSQL internals, Debezium, careful planning, and a few well-placed bash scripts. SPEAKERS **Anton Borisov** architects real-time data systems centered on PostgreSQL. At Fresha, he designs zero-downtime migrations, Debezium-based CDC pipelines, and overall data strategy integrating Postgres with Kafka and Flink. His work spans query planning analysis, partitioning and indexing, autovacuum and bloat optimization, and performance tuning under high-concurrency workloads. He also builds downstream lakehouse integrations with Iceberg, Paimon, and StarRocks. Anton publishes technical deep-dives on PostgreSQL internals, streaming infrastructure, and production reliability at medium.com/@borzoniusy **Vlad Bokov** is a Staff Engineer at Fresha working on systems behind activity feeds and communication between partners and customers. He deals with what breaks at scale: PostgreSQL under heavy write load, WAL bottlenecks, replication issues, Kafka pipelines, and zero-downtime migrations. Most of his work is about making production systems behave: fixing what is slow, unstable, or too expensive, and making trade-offs that hold up under pressure. He works across Snowflake, StarRocks, PostgreSQL, Elasticsearch, and Redis, and is currently exploring newer streaming approaches, including Apache Fluss, for real-world workloads. *** THE OFFICIAL BITS The meet-up abides by [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/).

uSwitch is located on the first floor of the ZPG building at 5 Copper Row, London, SE1 2LH, London (Click on the map for directions) What 3 words location: [https://what3words.com/puts.sudden.else](https://what3words.com/puts.sudden.else) The Clojure dojo is a collaborative way to learn Clojure/ClojureScript through practice. The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken). Example challenges for the coding dojo are listed on this website: http://www.londonclojurians.org/code-dojo/ Various past exercises have been loaded to [https://github.com/ldnclj](https://github.com/ldnclj/lisp1.5/blob/master/src/lisp1/5.clj) # Approximate schedule: 18:40 Doors open and start collecting suggestions 18.45 Pizza should have arrived 19:00 Quick intros and vote on suggestions 19:15 Break out into groups and start practising 20:45 Gather together for a quick show and tell # What should I bring? We organise into small groups, so if you have a laptop with a working Clojure environment please bring it along (there are lots of online Clojure environments, so you can just use your browser too). # How do I get in to the building? At the glass doors press the buzzer to inform the security guard you are here. Say you are here for the event on the first floor. Is there way to talk with the Clojure community? Why yes. The Clojurians Slack channel is full of friendly people who love to try and help. People based in London are often in the #clojure-uk channel. Sign up for a free account to the Clojurians Slack community via http://clojurians.net/ What is Clojure? Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

Regulators are increasingly turning to sophisticated data analysis to catch financial wrongdoing. From insider trading to market manipulation, agencies like the FCA and SEC are now building cases around one controversial line of reasoning: that certain patterns of trades simply couldn't have happened by chance. Join our small, informal RegTech Meetup for a deep dive into the world of data-driven enforcement. While the mood takes us, we'll chat about how regulators are using algorithmic surveillance and statistical modelling to detect suspicious behaviour. Afterwards we'll just chat. Whether you're working in compliance, financial services, law or data science—or simply fascinated by where technology and justice collide—this session is for you. The topic should give us all plenty to discuss and think about. Please come ready with questions, comments and suggestions. Notes: 1. As per our group's guidelines, we will ask for a small £5 donation on the day to help keep things running. 2. If you have any difficulty finding the venue or have questions beforehand please contact our WhatsApp group: https://chat.whatsapp.com/KpXlPokyOXWH4Nol0NDdzX?mode=hqctcli 3. We've moved the venue to Canary Wharf in the hope that this is more convenient for our members but please share your thoughts on where we should meet next. Do you have any suggestions as to frequency, timing and format?

🎉 Come along to the London Scala Talks! 🎉 In this event you'll hear from Haoyi Li, Martin Durchov and Adam Deegan. **Agenda** 6:00pm - 🥤 Doors open. Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Haoyi Li: Scripting on the JVM with Scala 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan, vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ Martin Durchov: ScalaMeta: Treating Scala code as data 8:10pm - 🗣️ Adam Deegan: Practical Java Interop for Scala Effect Systems 8:30pm - 🥤 Socialising: Grab a drink and let's discuss the talks. 9:00pm - 🍻 Join us in a pub to discuss the talks! 🌐 **This event may have a live stream** Watch this space for more details. **🗣️ Haoyi Li: Scripting on the JVM with Scala** This talk will explore the use of Scala as a scripting language, replacing the Bash and Python scripts common throughout the industry. ⭐ Haoyi Li ⭐ Li Haoyi graduated from MIT with a degree in Computer Science and Engineering, and since then has been a major contributor to the open source community. His projects have over 10,000 stars on Github, and are downloaded over 20,000,000 times a month. Haoyi professionally built distributed backend systems, programming languages, high-performance web applications, and much more. **🗣️ Martin Durchov: ScalaMeta: Treating Scala code as data** Scala source code is usually something we write and hand off to the compiler. But what if we could parse it, inspect it, build it, and transform it all from regular Scala code? ScalaMeta is the metaprogramming library that makes this possible, and it underpins a lot of modern Scala tooling ecosystems: Scalafmt, Scalafix, and Metals are all built on it. In this talk we'll look at what ScalaMeta is, how its AST models Scala programs, and the core operations it provides: parsing, quasiquotes, tree traversal and more. We'll then turn to how we use it at Quantexa, where it powers code generation for our clients. Along the way we'll cover practical patterns that make code generation manageable at scale, and the rough edges you should know about before adopting it yourself. ⭐ Martin Durchov ⭐ I graduated from UCL in 2019 with a MSci in Theoretic Physics and started work in TxOdds, a small company focused on ultra-fast data streaming and processing, where I first encountered Scala, working with Typelevel libraries. Since January 2025 I have been working at Quantexa in the team responsible for data ingestion and processing also relying heavily on the Scala functional libraries and ScalaMeta. **🗣️ Adam Deegan: Practical Java Interop for Scala Effect Systems** Interfacing with a highly autonomous Java library in a functional manner is difficult. In this talk we'll explore the ways in which we've approached this; issues we found along the way; and the trade-offs between purity and pragmatism when there's a runtime which isn't yours to control. ⭐ Adam Deegan ⭐ Adam Deegan graduated from the University of Bristol with a degree in Computer Science in 2021 and has worked at Quantexa ever since. He started off as a Data Engineer and moved into software engineering a couple of years ago, working on the addition of a case management capability. His first true programming love was making Minecraft mods. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

A big thank you to our sponsors [The Scale Factory](https://rebrand.ly/scalefactory) and [Cloudscaler](https://rebrand.ly/cloudscaler)! **Programme:** 18:00: Arrival, registration 18:15: Talks start 20:00: Networking with food and a drink provided by the generosity of our sponsors. **Talk 1:** ***Real-Time Sign Language in the Cloud: Building Accessibility Infrastructure on AWS with Alex Le Peltier*** Accessibility is too often an afterthought - bolted on at the end, limited by budget, or simply impossible without a human interpreter in the room. Signapse is changing that. In this talk, Alex Le Peltier, CTO of Signapse, will show how a proprietary GenAI model hosted entirely on AWS is delivering real-time AI sign language at mass-market scale - from live flight announcements at Heathrow to Netflix live streams. By combining AWS infrastructure with custom and public LLMs, Signapse has built a platform that fills the critical gap where interpreters can't be present, freeing up scarce interpreter resources for where they matter most. **Alex** is a serial startup-er and tech leader with over 13 years of experience in both the public and private sectors. He’s passionate about understanding what challenges are faced by the deaf community and building innovative solutions that make a difference in people's lives. **Talk 2:** ***Agentic Coding For 100 Developers with Daniel Jones.*** How has a $3b Stockholm SaaS company transitioned 100 developers to AI-native development over a few weeks? Daniel shares how he helped Odevo with exactly this, but the answer might be more than you expect - it involves just as much discovery and psychology as it does training. Learn about the social and business prerequisites for such a transformation, the syllabus that enables developers to use multi-agent workflows, and how 'one-and-done' training is insufficient for this type of behavioural change. **Daniel** is Head of Product at re:cinq, an AI-native transformation consultancy, and a CTO Craft 100 member. He founded cloud consultancy EngineerBetter, spent six years helping banks, government and defence organisations deliver software faster, then scaled and sold the business. Now he focuses on agentic coding, AI-native engineering, and software factories - with a practical, engineer-first perspective: fix your path to production before you let agents anywhere near it. **Do you have a story to share?** If you are interested in speaking at one of our events, please check out our [call for papers here](https://awsuguk.org/call-for-papers/).

**Agenda :** * 4.45 to 5.00 PM ET: Food and Networking * 5.00 to 5.50 PM ET: "Hands-On : GitHub Copilot SpecKit" Hello Everyone! Please join us for our April 14th edition of the AI-ML MeetUp. **Please note this is an in-person meeting and light refreshments/food will be provided. You will need a government-issued ID to enter the facility.** **Title:** Hands-On : GitHub Copilot SpecKit **Description:** Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them. In this hands-on lab, we will be covering building your application using SpecKit. Pre-requisites: VSCode v1.107, GitHub Copilot, Python 3.13 + uv, Git installed. **Location:** The meeting will be hosted in the Applied Information Sciences ( AIS ) office in Reston, at 11440 Commerce Park Dr # 600 · Reston, VA. The location is also right off the Silver Line metro's Wiehle-Reston Metro Station. **Parking:** Parking is paid and can be validated at the AIS office reception. We will meet in Room Lake Anne. We hope to see you all there!!!!

We invite you to an in-person session in Seattle exploring the real impact of AI on knowledge-driven industries — from shifting economics and the disruption of traditional SaaS and consulting models to where organizations can still build lasting competitive advantage. As AI platforms like ChatGPT, Claude, and Gemini continue to redefine how work gets done, organizations face a critical question: how can they adapt, remain competitive, and create lasting value? We’ll discuss practical strategies for integrating AI while preserving human expertise, along with actionable approaches to upskilling teams for an AI-driven workplace. Drawing on real-world experience from training thousands of professionals and deploying AI solutions, this session will provide clear, applicable insights for today’s evolving landscape. Following a short presentation, the session will open into an interactive discussion where attendees can share perspectives and explore key questions around the evolving role of humans, organizational adaptation, and staying competitive in an AI-first world. **Who should attend:** • Executives and managers in SaaS, consulting, and knowledge-driven organizations • Professionals exploring AI upskilling and workforce transformation • Anyone interested in the future of AI and knowledge work 📍 **Location:** Data Science Dojo, 5010 148th Ave NE, Suite 200A, Redmond, WA, United States 🔗 **Google Maps:** [https://lnkd.in/d8WA-yNc](https://lnkd.in/d8WA-yNc) **💻 Online Access:** A livestream will be available for those unable to attend in person; however, the full interactive experience is reserved for in-person participants.

We will be meeting at Starbucks to learn together. Come with an online class you're already going through or an interest and we will try to connect you with a course where you can learn it. Already have a skill you want to contribute to a Kaggle Datascience competition? We will work on these too! Laptop required :)
