**Join us for a joint meetup with our friends from Qodo and Tessl** AI coding agents are increasingly embedded in production workflows, but their failure modes are often poorly understood, difficult to detect, and even harder to evaluate systematically. ​This session examines how agent-based systems degrade under real-world conditions, focusing on three critical dimensions: reliability, code quality, and security. We’ll look at where current evaluation approaches fall short, how non-determinism and context drift impact correctness, and why seemingly “successful” generations can still introduce latent defects or vulnerabilities. ​If you’re building, evaluating, or deploying AI agents in production systems, this session will provide a grounded view of where they fail and what it takes to make them robust **Agenda** * ​​​6:00pm Venue opens * ​Join us for Drinks and Pizza! * ​​​6:30pm **Hidden Failure Modes for AI Agents** by Nupur Sharma * ​6:50pm Panel Discussion * ​**Panelists** * ​**Simon Maple -** Developer Relations at Tessl * ​**Brian Vermeer** \- Staff Developer Advocate at Snyk * ​**Nupur Sharma -** Solutions Engineer at Qodo * ​**Kunal Kushwaha -** Senior Developer Advocate EMEA at Cast AI **SPEAKERS** **​** **Simon Maple - Developer Relations at Tessl** ​Simon Maple is the Head of Developer Relations at Tessl, and AI Native Dev co-host.

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.**

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.

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.
