Come along and grab a drink! 6:35pm - 🗣️ Introduction 6:40pm - 🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules 7:20pm - 🍕 Intermission: Join us for some free food and drinks! Vegan and vegetarian options are provided. Let us know if you'd like something special - we'd be happy to accommodate. 7:50pm - 🗣️ David Lebl: Complexity is a Sin, But Hexagons Forgive 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 will not have a live stream** We hope to see you there in person. **🗣️ Przemysław Pokrywka: Ports and Adapters for People on Tight Schedules** Focus on software architecture is not always associated with pragmatism in common perception. 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?

A laid-back lunchtime of friendly chess in the charming surroundings of Russell Square, Bloomsbury (or in The Atrium Cafe of The Imperial Hotel across the road, if it rains). Whether you're new in town and looking to meet new people, craving some social games, or live/work/study nearby, all are welcome. Chess sets are available to borrow, and there are optional food/drinks from the cafe next to the chess tables. Please don't bring outside food/drinks (other than water), and buy something if you use a cafe table (no need when using the chess tables, which have boards printed on them). This will be a hosted event - if you're the first to arrive, you'll see your host sitting at one of the chess tables with a chess set. Feel free to write in the event to confirm you're going and encourage others to come along. Most of those attending are from other social media groups, so numbers are usually higher than they appear here. Have fun! :)

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.

Your survival depends on knowing who you can rely on. But how can you tell who your real friends are? How can you determine if a person will help make a joint venture successful? Is there a way to predict behavior? Yes. There are fundamental elements to human behavior. When you know them you have insight into your fellow man, and just by observing how people act, you will know *everything* about them. #### On this lecture you will learn: * The important role of trust in human relationships. * The Hubbard Chart of Human Evaluation—the tool to know true character and predict what people will do. * How to evaluate others accurately and guarantee a more certain future for yourself and those you care about. With the knowledge you learn on this course, you will have tools to know who you can trust and who you can depend on. *“Trustworthiness is a highly esteemed commodity. When one has it, one is considered valuable. When one has lost it, one may be considered worthless.”* *—L. Ron Hubbard*

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.

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

# Learn how to use open-source harnesses like OpenCode & Pi w/ your own LLM and with it, build a real-world application **Registration to this event is only valid through the Luma platform:** [https://luma.com/11txn8gq](https://luma.com/11txn8gq?utm_source=meetup-dot-com) ​Hello code campers! ​Since everyone is talking about using harnesses such as **Anthropic Claude** or **OpenAI Codex**, meaning, everyone is probably tired of hearing about them, we've decided to go in a different direction and explore other, lesser known things such as, [OpenCode](https://opencode.ai/?utm_source=luma) and [Pi DOT Dev](https://pi.dev/?utm_source=luma). Come and join us and learn how to work with a wide range of open-source large language models (**LLMs**) such as **DeepSeek V4**, **Gemma**, **Kimi K2**, and **GLM** across various local-first environments. This comprehensive workshop is designed to teach you what is a code harness, how many types of them there are out there (you might be familiar with **Claude Code** or **Codex** or **CoPilot** but there are others and since the big-tech companies are moving to token-based usage, why not run your own solution locally). Also, we'll explore how to go about having effective agentic coding workflows while benchmarking model performance and hardware requirements. ​We will go through the setup process, focusing on how to install the desired LLM runner like Ollama or LMstudio locally. ​This will be our **7th** event in our series of **local-first, open-source** AI events; therefore, we will try to focus on building a setup that doesn't depend on Big Tech but on smaller open-source tech instead. ​This workshop is open to all levels, from beginners to experts. ​Bring your laptop (make sure it's fully charged as local LLMs tend to be power-hungry), and don't forget to bring your coding gear (hoodie). ​This workshop will be most likely accompanied by a guest speaker (TBD). *** ## ​Prerequisite ​Prerequisite: a local Ollama, LMStudio installation or equivalent (but if you don't have any of that, don't worry, come a bit early and we will help you). ​If you want to take a quick look at the slides from the previous events fell free to do so: [​https://andysign.github.io/ai-london-01/](%E2%80%8Bhttps://andysign.github.io/ai-london-01/) (Ollama); [​https://andysign.github.io/ai-london-02/](%E2%80%8Bhttps://andysign.github.io/ai-london-02/) (LangFlow, not really related but still) [​https://andysign.github.io/ai-london-03/](%E2%80%8Bhttps://andysign.github.io/ai-london-03/) (private RAG w/ Anything LLM) [​https://andysign.github.io/ai-london-04/](%E2%80%8Bhttps://andysign.github.io/ai-london-04/) (AI-native browsers) [​https://andysign.github.io/ai-london-05/](%E2%80%8Bhttps://andysign.github.io/ai-london-05/) (OpenClaw basics) [​https://andysign.github.io/ai-london-06/](%E2%80%8Bhttps://andysign.github.io/ai-london-06/) (OpenClaw advanced) *** ## ​Agenda for the evening (Subject to change) ​**18:00 - 18:30 Arrival and networking** Mingle with fellow developers over refreshments. ​**18:30 - 18:45 Introductions** Intro and a bit of audience engagement. ​**18:45 - 19:40 Workshop** ​Hands-on technical workshop (if you are non-technical it's OK, tag along). ​**20:30 - 20:45 Guest Speaker** ​**20:30 - 21:00 Networking** ​**21:00 - Closing remarks and follow-up** ​ **END:** Carry on the fun at a nearby pub around the corner. *** ## Event Venue We'd like to extend a heartfelt thank you to **Encode Club**. [Encode Club ](http://encode.club)has spent over five years fostering a global community of developers, researchers, and founders in Web3, AI, and emerging technologies. The [Encode Hub](http://hub.encode.club) brings everything together under one roof, providing a dedicated environment for collaboration and innovation through meetups, co-working, and in-person events.

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

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!
