Decentralized Systems & Applications

**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.

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/).

A unique and powerful therapeutic method for self-exploration, understanding core behaviours, removing blocks, and reintroducing movement and growth. It is used as a major resource in supporting healthy relationships, working through trauma, and assisting in depression treatment. **Issue Holder (client) and Representative spaces are available, please follow the link to book:** **For Representative (Participant) Booking £35** **[https://calendly.com/illiadato/in-person-family-constellations-evening-workshop](https://calendly.com/illiadato/in-person-family-constellations-evening-workshop)** **For Issue Holder (Client) Booking £175:** If you wish to attend as an Issue Holder at this workshop and have your own Constellation done please email your request to: [ih@londonconstellations.uk](http://ih@londonconstellations.uk/) Read comments of workshop participants here: [https://bit.ly/33Asprs](https://bit.ly/33Asprs) **WHAT ARE SYSTEMIC CONSTELLATIONS?** The Systemic Constellations method is a unique therapeutic process of exploration of the forces that move us in life. Such forces are often appearing as difficulties or a sense of being 'stuck' in life, affecting our behaviour, relationships, career, health/wellbeing, or even financial circumstances. This method provides a three-dimensional ‘map’ of one’s life as it is at present. It is a simple yet powerful way to explore entanglements and blockages in our personal life and our family history. The method brings awareness and clarity into personal challenges by focusing the client on the root cause of such difficulties. Constellations provide an opening for a positive life shift and present ways for deep healing processes to occur. **WHAT HAPPENS IN A CONSTELLATION SESSION?** In Constellations work the ‘client’ is referred to as the ‘Issue Holder’. The method uses workshop participants as ‘Representatives’ to stand in for key people in the client’s life such as family members, colleagues, partners, ex-partners, etc., sometimes ‘abstract’ concepts such as an emotion, country of origin, religion, or destiny are also represented. All participants are invited to take part as Representatives. Workshop participants often report (see reviews: [https://bit.ly/33Asprs](https://bit.ly/33Asprs)) experiencing profound insights into their own lives by simply witnessing the process, regardless of how they choose to take part. **WHY DOES THIS WORK?** Scientific research shows that the experiences of your ancestors can determine your behaviour today and affect future generations.\*\* Recent scientific research into DNA reveals that a component named epigenetics is embedding the effect of a traumatic experience by altering the genetic structure. It means that some of our behaviour patterns can be attributed to traumatic events in our family history.

Our group provides a **safe space** where deep personal work is done and where maintaining confidentiality and respect for each other's privacy is paramount. **\*\* DNA research paper and news article links:** Discover - Grandma's Experiences Leave a Mark on Your Genes [https://bit.ly/3dLwEkK](https://bit.ly/3dLwEkK) BBC News - "Memories" pass between generations [http://bbc.in/1dNShPe](http://bbc.in/1dNShPe) **Facilitated by Illi Adato** MA Lon\.

**Giving the Here-and-Now a Chance Constellation Workshop** Saturday 18 April 2026 10 to 530pm £120 We will work with small, experiential constellation exercises designed to deepen awareness of the personal and ancestral influences shaping our thoughts, actions, and reactions—often colouring our present-moment experience. This process supports disentangling from what does not belong to us, allowing our healthy adult self to take the lead in how we respond and act. The focus is on identifying and releasing patterns that originate in our family system or adaptations formed in early life that continue to influence us today. By doing so, we create space to be more present, available, and grounded in our here-and-now experience. All relevant information will be shared at the beginning of each day. To register please send a message to: info@emersonbastos.co.uk Future London events: **5 Elements Constellation workshop** Saturday 6 June Saturday 18 July Saturday 5 September 10 to 17:30h 5 Issue holder £140 and up to 11 Representatives £70 **Earth Element Constellation Workshop** Saturdays 24 October & 7 November 10 to 17:30h Fee: £230 **5 Elements Constellation workshop** Saturday 12 December 10 to 17:30h 5 Issue holder £140 and up to 11 Representatives £70 Join us for this in person confidential and supportive constellation group experience. Constellation work allows us to work with the resonance field revealing hidden dynamics, entanglements and burdens that we unconsciously got involved in and make our journey forward in life less than it could be. The focus of the work is “Health” in the broadest sense of the word. I define this as a movement towards the true authentic self in a clear and objective way.

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 .

Welcome to our April event. We're delighted to welcome [Alex Le Peltier](https://www.linkedin.com/in/alex-le-peltier/), Chief Technology Officer, Signapse and [Daniel Jones](https://www.linkedin.com/in/danieljoneseb/), Head of Product, re:cinq. **Alex** answers - “what if AI could sign for the entire world - in real time?” From Heathrow flight announcements to Netflix live streams, find out how Signapse is making accessibility possible at scale on AWS. **Daniel** answers - “how do you turn 100 developers AI-native in just a few weeks?” Daniel reveals the psychology, strategy, and surprising human side behind one of the most ambitious agentic coding rollouts in enterprise tech. 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/).

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
