Agents are writing code, running workflows, and building other agents. ​ The challenge isn’t basic functionality. It’s getting these systems to operate predictably in production, and integrating them into how teams build and ship software. ​This session covers both. ​ From a production lens: how to build agentic systems using spec-driven development, structured context, and evaluation loops that hold up at scale. ​From a human lens: what breaks when agents become collaborators. Ownership, coordination, and how teams actually adapt. ​Speakers: ​**Clifton Cunningham** ​**Member of Technical Staff, [guidemode.dev](https://guidemode.dev/?utm_source=luma) \| Former CTO at DailyMail\, Infinitas Learning\, TES Global** ​Clifton will explore what happens when AI agents become part of your team. Drawing on experience leading large-scale engineering organisations, he’ll unpack the human, cultural, and operational challenges of working alongside AI colleagues. ​**Alfonso Graziano** ​**AI Tech Lead\, Nearform \| Author of *AI-Native Software Engineering*** ​Alfonso will walk through how to build agents that build and maintain other agents. A practical, production-focused session covering spec-driven development, context engineering, evaluation loops, and how to make agentic systems reliable at scale. ​ Join us for pizza, drinks, and practical AI insights.

Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Anton Borisov - Distilling Kafka's Binary Protocol into Elixir** We'll trace a produce request to show what any Kafka client has to get right. In the BEAM ecosystem, erlkaf wraps librdkafka, brod implements the protocol in Erlang, and [kafka_ex](https://hex.pm/packages/kafka_ex) goes pure Elixir. Kafka_ex's approach is to generate serializers at compile time from Kafka's own schema definitions: plain structs, pattern matching, structural boilerplate isolated from the logic you actually think about. That design is what let us jump two major versions ahead and adapt to significant protocol changes. Let's dig into the idea, the code, and the tradeoffs. **Session 2: Evadne Wu** **\- JavaScript Execution Strategies in Elixir\-based Agent Frameworks** We'll look at integration points between elixir agents (in the AI fashion) and JavaScript execution, and all the foot guns involved. *The event is kindly sponsored by* [Fresha](https://www.fresha.com). **Time** Doors open at 18, start at 18.30. **Venue** Fresha The Bower, 207-211, Old St, Tower, London EC1V 9NR **Refreshments** Food and drinks will be provisioned on the day. **IMPORTANT**: **If you wish to take photos and post online during the event, please notify organisers first, so that attendees can opt-out from being in photos.**

BOOK YOUR TICKET 👉🏼 [HERE](https://itsadate.club/event/coffee-club-speed-dating-6/). Just steps from King’s Cross Underground and St Pancras stations, you’ll find Drake & Morgan — a trendy, informal venue with a easy-going daytime vibe—the perfect setting for coffee, conversations, and new connections. Whether you’re an espresso enthusiast, a matcha man, or the queen of chamomile, your first cup’s on us at this event full of warm introductions and laid-back laughs. And if you’re feeling a little *chai*, don’t worry — our host will be on hand to help everyone feel at ease and enjoy a great morning. You’ll be welcomed at 10:00, shown where to collect your complimentary cuppa, and given an optional name sticker, a pen, and a note card to track each of your dates. Our host will then give a quick introduction to explain how the event will unfold. The set-up is simple: ladies will be seated at numbered tables, and when dating begins, gents will rotate every five minutes for a fresh new ‘shot’ at romance. Your host will guide each changeover to ensure everyone meets all attendees over the course of the morning. About halfway through, there will be a 15-minute break — perfect for stretching your legs, topping up your drink, or chatting with fellow guests you haven’t yet met. After that, we’ll jump right back into the second round of dates. Once the final date wraps up, the bar stays open for more networking — or why not take a stroll down the Regent’s Canal path with your newfound connections? After the event, you can log in to your dashboard to leave feedback and find out if any mutual matches were made. If you have any questions, feel free to contact James on 07517 065 492 or james@itsadate.club. So grab your cup, take a seat, and get ready to espresso yourself — you might just find the perfect blend.

We are back! This is going to be a monthly IN PERSON meet up in London. A very big thank you goes to Accurx who is hosting us in their amazing Shoreditch offices. This will include access to facilities including coffee! 😻☕️ **Want to know more? 👇** As with all CoffeeOps, this is an interactive, chatty, build your own adventure type of meet-up. Instead of booking in experts to *learn* *from*, we gather a group of practitioners to ***learn*** ***with***. We have been running for over 4 years now and often get feedback that this is the most useful meetup people join! The event is approximately 90 minutes and always starts by brainstorming topics to discuss. The group then votes on the most relevant/interesting to them and we then cycle through the topics trying to discuss each deeply, but in a time bound slot. To get an idea of topics, you can check out our remote board [here](https://easyretro.io/publicboard/h404NF84Uje4tCcxpJdHr4Ycs9B3/a4a35d2b-181b-409b-832e-a729be1af79c). The general gist is anything is fair game, though we tend to revolve around software delivery and definitely lean towards the more Ops-y or DevOps-y side of things.

Join us both online and in London for a deep dive into how JVM developers can lead the next wave of innovation with agent-based systems. We’re excited to host Rod Johnson, creator of Spring, as he introduces Embabel, a new framework designed to push Java and Kotlin to the forefront of agentic AI. From building safe, testable, and enterprise-ready AI agents to rethinking how Java fits into the Gen AI ecosystem, this session will give you a front-row seat to what’s next.

Building predictable, safe, manageable, testable agents that integrate with existing enterprise systems is critically important to us all. ​In this session, Rod Johnson will show how JVM developers can be central to unlocking the business value of agentic AI, using the Embabel agent framework: [https://github.com/embabel/embabel-agent](https://github.com/embabel/embabel-agent) Embabel is an innovative framework for Java and Kotlin developers, seamlessly integrated with Spring. Built in Kotlin, it aims not to play catchup with Python frameworks like Crew AI, but to leapfrog them to be the best agent framework, period. ​Embabel innovates in several ways. It introduces a planning step that maximizes autonomy while maintaining determinism and safety. It is type safe, ensuring excellent toolability and avoiding errors in prompts. It enables developers to use a rich domain model, defining not just types but behavior exposed to user code and to LLMs as tools. ​ Read more about the [vision](https://medium.com/@springrod/the-embabel-vision-967654f13793?utm_source=luma); and also the call to action for Java developers in recent Devoxx keynote: [https://www.youtube.com/watch?v=dbx1_P7W1DM](https://www.youtube.com/watch?v=dbx1_P7W1DM&utm_source=luma) **​Rod Johnson, Creator of the Spring Framework and Embabel Agent Framework** ​ Rod Johnson is a developer, author, entrepreneur and advisor.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
