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 .

🎉 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?

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
