June Edition ✨✨! We will be at the MongoDB London office! Django London Meetup is a monthly meeting to discuss Django, Python, the web, and related topics. The meetups are open to all with an interest in building websites with Django. (in-person only event, no streaming) **Talks:** **AI Agents Need Memory Too: Building Systems That Remember What Matters — Abigail Afi Gbadago** AI agents are only as good as what they can remember, but deciding what to store, where to persist it, and how to retrieve it at the right moment is harder than it sounds. This talk walks through a practical framework for architecting memory systems for agentic applications, covering memory types, storage patterns, retrieval strategies using vector search, and managing the full memory lifecycle in production. Afi is a Senior Software Engineer and Developer Advocate (MongoDB). She serves as Vice President of the Django Software Foundation, a Fellow of the Python Software Foundation, and is a Microsoft MVP for Python and Web. Afi is passionate about building great software and stronger tech communities. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Replay Failed Python Runs: Reverse Debugging When Logs Aren’t Enough** **\- Nathan Matthews** Reproducing Python failures from a traceback alone is often impossible once the request is gone or the environment has changed. This talk introduces Retrace, an open-source reverse debugger that lets you record, replay, and step backwards through a failing run, giving both developers and AI agents concrete evidence for debugging. Nathan Matthews is Co-founder and CTO of Retrace Software. He has spent his career building complex Python and distributed systems across fintech, developer tools, and data platforms, including roles at 10x Future Technologies, Digital Asset, Elsevier, and Droit. At Retrace, Nathan leads the technical work behind deterministic replay and reverse debugging for CPython. **Want to share your Django or Python knowledge?** We’d love to feature your talk!

Looking to organise a first meet up for a Dessert Social. Am confirming venues but will scout some good dessert places and the format for the meetup. The format will likely be a dessert oriented location that has coffee / tea etc.. so we can get to know each and chit chat Please do confirm if you can make it.

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. Damien is also active in the cloud community, serving as a content creator, user group leader and public speaker. **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/).

🎉 Come along to the London Scala Talks for a deep dive into functional architecture! 🎉 In this event you'll hear from David Lebl and Przemysław Pokrywka. **Agenda** 6:00pm - 🥤 Doors open. 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?

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
