Terms such as architecture astronautics and the ivory tower stereotype highlight the perceived disconnect between many architects and the realities of day-to-day code maintenance. Too often, architectural patterns are applied with insufficient understanding, leading to cargo-cult adoption and increased waste in the software development process. When applied in the right context, however, certain architectural approaches can be powerful enablers. In this talk, I would like to share the story of a serverless application in which elements of the Ports and Adapters architecture made a tangible, positive difference. ⭐ Przemysław Pokrywka ⭐ Husband, dad, grandad, software engineer. Functional Scala enthusiast with imperative OOP Java background. Fan of the command line. **🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive** A visual journey from spaghetti to sanity. This talk traces how cognitive load accumulates in unconstrained codebases, how domain-driven design and bounded contexts restore order, and how hexagonal architecture provides a practical, forgiving structure for real-world systems — all laid out on a single zoomable canvas where every example links back to the bigger picture. ⭐ David Lebl ⭐ David is a software developer with a CS background and 5 years of Scala and FP experience. He leads a small team, occasionally survives his own accidental complexity, and is here to share what he learned the hard way. ———————————————————— 🗣️ Would you like to present, but are not sure how to start?

Welcome to our June event. We're delighted to welcome [Marina Kim](https://www.linkedin.com/in/marinawebdev/), Tech Lead, Vidatec and [Damien Jones](https://www.linkedin.com/in/mrdamienjones/), AWS Consultant, Steamhaus You've seen the AgentCore demos. **Marina** has taken them into production, and lived to tell the tale. Tonight she's giving us the engineering reality behind building AI agents on AWS with Amazon Bedrock and tooling: what breaks, what costs you, and what actually ships. Five weeks. A brand new business. A Crufts deadline. **Damien** didn't whiteboard this one - he shipped it. Tonight he's walking us through every decision that made it possible: AWS CDK, Amplify, Q Developer, and Kiro working together under real pressure. A big thank you to our sponsors [Cloudscaler](https://rebrand.ly/cloudscaler), [Rayo](https://rebrand.ly/rayo-cloud) & [The Scale Factory](https://rebrand.ly/scalefactory) 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: ***AgentCore vs Reality: Lessons from Building AI Agents on AWS with Marina Kim*** In this talk, I will explore the reality of what happens when you try to build an AI agent on AWS using Amazon Bedrock and tool calling, inspired by still new and emerging AgentCore patterns. Through a live demo and practical examples, I’ll walk through what worked, what didn't work, and the unexpected challenges that appear when moving from theory to implementation, including hallucinations, incorrect tool usage, and trade-offs around cost and latency. The goal is to give a realistic, engineering-first perspective on building agentic systems today, and help developers understand where these patterns are useful and where they still fall short. By the end of this talk, you’ll have a clear understanding of how to approach building AI agents on AWS, what pitfalls to expect, and how to make informed decisions when applying agentic patterns in real-world systems. **Learning Takeaways** * How to approach building AI agents on AWS using Amazon Bedrock and tool calling, with focus on emerging AgentCore patterns * What actually happens when you move from theory to implementation, including common failure modes like hallucinations, incorrect tool usage, and overconfident decisions. * How to iteratively improve an agent by testing, identifying issues, and introducing guardrails and constraints * How to evaluate trade-offs between autonomy, reliability, cost, and latency in agentic systems **Marina** is a Tech Lead at Vidatec working with web, mobile, MS Teams and AI solutions across multiple industries. She has significant experience working with AWS services, managing deployments and maintenance across multiple production workloads. Marina is a founder of Catbytes - online community for women in tech and a co-organiser of AWS UG UK and AWS AI In Practice community events Talk 2: ***Best in Show: Building a Crufts-Ready AWS Business Platform in 5 Weeks with Damien Jones*** A new dog training business is launched. You have 5 weeks to develop a new production-ready platform before Crufts: the world's biggest dog show. Could you deliver? In this talk, I'll share the real-world journey of building WolfieAndFriends on AWS. We'll review my architectural choices, "build vs buy" decisions and the trade-offs made during those hectic early days. You'll learn how to use AWS serverless, IaC and AI services to enable rapid delivery, shorten development times and transform a greenfield project into a professional, scalable platform that pays the bills. Whether you're a startup founder or an enterprise dev, you'll walk away with a blueprint for rapid delivery without sacrificing long-term stability. Expect Amplify, CDK, Q Developer, Kiro and more! **Learning Takeaways** * How to make fast, defensible architectural decisions under genuine time pressure. * How to use AWS CDK, Amplify Gen 2, Q Developer, and Kiro as an integrated rapid-delivery stack. * Practical "build vs buy" trade-offs: what to own, what to delegate, and how to decide. * How serverless IaC enables safe iteration from greenfield to production. * A reusable blueprint for going from zero to a scalable, paying platform in weeks — not months. **Damien** is an AWS consultant, data specialist, and cloud enthusiast with a strong record of designing, building, and optimising cloud-native solutions. He has extensive knowledge of data engineering, DevOps and cloud architectures, fueled by a passion for using emerging technologies to solve complex problems and support data-driven decision making.

Unless otherwise announced this is an in-person social gathering for Smalltalkers to get together and talk about Smalltalk (the Programming Language!). Everyone is welcome from the grizzled and experienced to the merely curious.

A Rabble session is 1 hour of fun and social team games. Each game disguises high-intensity intervals within the rules, giving you an effective, all-body workout without even realising it. We play a bunch of different games at each session (like British Bulldog, Capture the Flag, Dodgeball, Frisbee and many more), and every class is different. Sessions are open to all, no matter your sporting ability. Each game is explained before we start, so there's no need to have played any of the games before. Come solo or bring friends! And stay at the end for the social part! Who knew getting fit could be this fun? **TO BOOK**: It's essential that you book onto sessions via our website, using the link below; due to restrictions on games and preparation times we cannot accept walk-ins, or late arrivals.

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.

**Important:** Register on the [event website](https://www.aicamp.ai/event/eventdetails/W2026061110) is required for admission. **RSVP on meetup is turned off** Welcome to the AI meetup in London, in collaboration with **Coder and Netmind**. Join us for deep dive tech talks on AI, GenAI, LLMs and Agents, hands-on experiences on code labs, workshops, and networking with speakers and fellow developers. **Agenda:** \* 6:00pm\~6:30pm: Checkin and Networking \* 6:30pm\~6:45pm: Welcome/community update \* 6:45pm\~8:30pm: Tech talks and Q&A \* 8:30pm\~9:30pm: Open discussion & Mixer **Tech Talk: Scale AI Workflows** **Speaker:** Eric Paulsen (Coder) Abstract: This meetup is for developers and platform teams who want to understand what it actually takes to move from AI experimentation to production-ready workflows. We’ll focus on how teams are redesigning their development workflows to work with AI, not just adding tools on top. That includes how to structure workflows, manage agents, and introduce the right level of control without killing developer velocity. No hype. No tool comparisons. Just a clear look at why most AI workflows fail and what actually works at scale. **Tech Talk: AI-DLC: Navigating the AI Development Lifecycle with Kiro** **Speaker:** Ryan Tan (AWS) **Abstract:** This session explores the evolving AI Development Lifecycle (AI-DLC) through the lens of Kiro's current capabilities and future direction. We'll cover Kiro's desktop/CLI deployment model and the path toward broader accessibility, early-stage developments around Kiro's upcoming autonomous agent capability, and how an agnostic philosophy — enabling choice of IDE, LLM backend, and cloud provider — shapes a flexible, developer-first approach to AI-assisted software development. Whether you're evaluating AI coding tools or architecting developer platforms, this session will give you a practical view of where the ecosystem is heading. **Tech Talk: Earning the Right to Step Away: AI Agents in Everyday Practice** **Speaker:** Billy Michael (GlobalLogic) **Abstract:** You've seen the demos. This is what happens after them. It's a look at the agents and skills we actually run inside GlobalLogic, day to day, on our own engineering and business work, and what it took to trust them. We started where most teams do: Claude Code in a terminal, with a human framing every task and pressing enter. The interesting part begins when no one is at the keyboard. I'll walk through the pattern we use to get there: build a skill by hand, live with it until it's boring, then let an event pull the trigger. The unit is always the same, a skill; what changes is how much autonomy the stakes justify. **Tech Talk: Trustable Agentic AI** **Speaker:** Xiangpeng Wan (Netmind) **Abstract:** NetMind.AI's [NarraNexus](https://www.narra.nexus/?utm_source=AI+Camp&utm_medium=Page&utm_campaign=20260611+Event) is a ready-to-run team of agents that already remember, collaborate, and use tools. Start from a template, or compose your own. **Speakers/Topics:** Stay tuned as we are updating speakers and schedules. If you have a keen interest in speaking to our community, we invite you to submit topics for consideration: [Submit Topics](https://forms.gle/JkMt91CZRtoJBSFUA) **Sponsors:** We are actively seeking sponsors to support AI developers community. Whether it is by offering venue spaces, providing food, or cash sponsorship. Sponsors will not only speak at the meetups, receive prominent recognition, but also gain exposure to our extensive membership base of 20,000+ AI developers in London and 500K+ worldwide.

We are excited to host our coding dojo with Spektrix! We'll kick off with an introduction to TDD, its core principles, and following disciplined emergent design. Through hands-on pairing and mob programming, you'll experience how writing tests first doesn't just catch bugs, it shapes cleaner, more intentional code from the ground up. **What about AI tooling?** We encourage the use of AI tooling! We will briefly walk through how such tooling can act as multiplier, not to shortcut the discipline of TDD. **Don't have AI tooling?** No problem. TDD is a discipline that stands on its own, with or without AI. But if it's something you'd like to try, we can pair you with somebody who has the tools set up. Join us for an evening of coding, food and drinks. Come and code along, share ideas, discuss best practices with Test Driven Development and learn from our expert Crafters and your peers in the London Software Craftsmanship community. **What’s the format?** After a short intro, we’ll get into groups/pairs or work solo, whatever people feel most comfortable with, and start building. You choose how you want to work and what language you want to code in. This session is about collaborating with others, becoming a better developer and building your network, in a fun, relaxed environment. We'll be sharing ideas, discussing best practices and using this as an opportunity to learn from our fellow coders. All levels of experience very welcome, if you want to brush up on your Test Driven Development skills or are a complete novice, do come along. All welcome! All you need to do is bring a laptop if you’d like to code along - please have your preferred language and editor setup. **Food and Drinks** Pizza and drinks will be provided upon arrival

Join us on June 11th from **6:00pm** for a Data Streaming meetup hosted by **Moniepoint!** **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name. For security purpose** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:15pm: Tom Scott, CEO, Streambased * 7:15pm - 8:00pm: *Abraham Imohiosen,* Engineering Manager * 8:00pm - 8:30pm: Q&A Networking. 💡**Speaker One:** Tom Scott, CEO, Streambased **Title of Talk:** Infinite Kafka? Rethinking Retention with Iceberg **Abstract:** Apache Kafka is designed for high-throughput, low-latency event streaming, not cost-efficient long-term storage. Yet we constantly see cases like event sourcing, audit/compliance, and large-scale reprocessing forcing that pattern onto it. As retention increases, costs grow linearly to support edge cases, one-time runs, and “checkbox” use cases. Can Iceberg help here? In this talk, Tom explores a hybrid architecture that separates hot and cold data while preserving Kafka’s log semantics. Using a combination of Kafka and Apache Iceberg, he demonstrates how to extend Kafka into low-cost object storage, enabling effectively unlimited retention without sacrificing performance or access patterns. The result is a unified log that supports both real-time processing and long-term replay, removing the traditional trade-off between cost and capability in Kafka-based systems. **Bio:** Long-time enthusiast of Kafka and all things data integration, Tom has more than 15 years of experience in innovative and efficient ways to store, query, and move data. Tom is currently CEO at Streambased, a company focused on unifying operational and analytical data estates into a single, consistent, and efficient data layer. 💡**Speaker Two:** Abraham Imohiosen, Engineering Manager, Fraud Prevention Tools. **Title of Talk:** From CDC to Decision: Kafka as the Fraud Detection Pipeline's Connective Tissue **Abstract:** Fraud detection isn't one system — it's a system of moving parts (databases, feature stores, rule engines, ML models, case management tools) that all need to agree on what just happened, in milliseconds. Kafka sits in the middle of it, and treating it as "just the message bus" leaves a lot of value on the table. In this talk, I'll walk through three jobs Kafka does inside Moniepoint's fraud detection pipeline: moving events between services, powering real-time aggregations and windowed features, and acting as a CDC source that turns database changes into the canonical stream feeding a final aggregate store, as well as routing evaluated events into the case management system for final decisioning. **Bio:** *Abraham Imohiosen is an Engineering Manager at Moniepoint, where he leads the Fraud Prevention team in building case management systems and machine-learning detection models that protect millions of customers and billions in transaction volume. He has over 10 years of experience across fintech and cloud-based architectures, having previously led the delivery of Monieworld Transfers and a savings product. Abraham holds an M.Sc. in Robotic Systems Engineering from RWTH Aachen University.* \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD

Short North Street Skates return Saturday, April 4 and we’re excited to get back rolling together. These weekly rollouts are a chance to move through the city as a group, build community, and create more visibility for skating and small-wheeled movement in Columbus. Details: Meet: 1160 N High St 9:30 AM meet 10:00 AM rollout All wheels welcome We’ll be skating through the Short North and surrounding areas at a steady, social pace. Routes will use a mix of streets and bike lanes, so comfort navigating the city is helpful, but you don’t need to be an expert. If you’ve been meaning to come out, this is a great place to start. Come solo or bring a friend!

A session on using Claude Code, Anthropic's AI coding agent, in real Unity development. We'll cover what coding agents are, where Claude Code fits, and how to apply it to an actual game project. The format is presentation-style, with live demos and time for questions throughout. After brief scene-setting on coding agents and what makes Claude Code distinct, we'll go problem-driven: demoing it live on a released Unity game and introducing each feature as a solution to a problem we hit. What to Expect: * An intro to coding agents and where Claude Code fits * A live demo on a real Unity project * Key features as solutions to real problems: 𝖢𝖫𝖠𝖴𝖣𝖤.𝗆𝖽, context management, hooks, skills, subagents, and MCP * Unity-specific pain points, including Domain Reload and MCP caveats * Putting it together All experience levels welcome. Food and drinks provided. *Note: meetup topics may change — check back for the latest details.*
