Behavior-Driven Development

Please join us for an evening of all things Umbraco - the latest news, community chat, and a talk or two! For 2026, we will be running both in-person and virtual meetups, alternating every month. For those who can't join in person, virtual attendance is available too, so you can join us no matter where you are! This month, we have **Owain Jones** talking about building friendly content editing experiences and **Markus Johansson** talking about building packages for Umbraco. **Owain Jones - Unlocking the Full Potential of Umbraco: Building Friendly Content Editor Experiences** Umbraco is often called "The Friendly CMS", and it absolutely can be when we, as developers, make the most of what it offers. In this talk, I’ll show how we can utilise Umbraco’s built-in features and community packages to build intuitive, efficient, and friendly experiences for content editors. **Markus Johansson - Extending Umbraco like a Swede** In this talk, Markus will share his learnings from over 15 years of extending Umbraco. We’ll get a brief overview of the possibilities introduced with the new backoffice “Bellissima”. He’ll also give us tips and tricks that is useful both when extending Umbraco for a specific project or publishing a package for the Umbraco Marketplace. There will also be food, drinks and some friendly socialising. What's not to like? 😄 Whether you are an Umbraco novice or a seasoned developer, this is your chance to meet like-minded people to talk about our favourite friendly CMS! No matter what your role is there will be something to learn and your chance to meet other members of the Umbraco community from Kent and the surrounding areas. Venue The meetup will be at Dragon Coworking in Rochester (7-8 New Road Avenue, St George's Hotel, Rochester, ME4 6BB), a short walk from Chatham train station and with free on-site parking.

Join us in London for a forward-looking conversation with product leaders building the next generation of autonomous, AI-driven systems. **Event Overview** AI agents are quickly advancing from basic automations to adaptive, goal-driven systems that can reason, act, and manage complex tasks. As they enter real products, teams must rethink how to design, ship, and scale intelligent experiences that remain both powerful and trustworthy. **01 - From Automation to Autonomy: What “Agentic” Really Means** Explore how AI agents differ from traditional automations, from decision-making and multi-step planning to real-time adaptation, and what this shift means for product strategy and user experience in the wild. **02 - Designing Trustworthy Agents: Safety, Reliability & Real-World UX** Examine the critical considerations behind building agents people can rely on, including transparency, failure modes, human-in-the-loop design, and the UX principles needed to ensure agents behave predictably and responsibly. **03 - The Next Frontier: Agent Capabilities, Ecosystems & Scale** Discover how emerging capabilities such as tool use, collaboration, and multi-agent systems are transforming what products can achieve, and what teams must consider when deploying agents at scale across industries.

**📣**AI didn’t just change how we build products, it exposed the cracks in how we design, ship, and make decisions. **This meetup brings together three perspectives on the real challenges of AI products:** getting users to use them effectively, managing unpredictability and trust, and rethinking product strategy when execution is no longer the constraint. Together, these talks shift the focus from technology to judgment, design, and product thinking. \#\# Agenda: **18:00** \- Gather & Mingle\. **18:30** \- Opening remarks\. **18:40** -"**Shipping AI features isn’t enough**" by Ellie Jacobs, Product Director LTX @ Lightricks **19:00** - **"Shipping Products That Are Almost Right"** by Meital Kochawi Levin, Senior Product Manager @ Bringg **19:20** - **"Product Strategy in the AI Era"** by Hadas Sheinfeld, VP Product @ ProductX.biz **19:40** \- Networking & Mingle Time **20:00**\- Close 🗣️First talk by **Elli Jacobs** **"Shipping AI features isn’t enough"** Users often fail to get value from AI-based features, because they don’t use them “correctly.” This talk explores the hidden gap between capability and usage, and how product teams can design experiences that guide users toward better outcomes without adding friction or requiring education. It’s about turning AI from something impressive into something reliably useful. 🗣️ Second talk by **Meital Kochawi Levin** **"Shipping Products That Are Almost Right"** Long before LLMs, non-deterministic systems forced teams to grapple with unpredictability, trust, and imperfect outcomes. This talk distills hard-earned lessons into a practical framework for building and managing such products—defining where accuracy matters, designing for failure, and turning users into active contributors to improvement. It offers a grounded approach to making “unreliable” systems feel dependable. 🗣️ Third talk by **Hadas Sheinfeld** **"Product Strategy in the AI Era"** AI hasn’t changed the essence of product strategy, but it has removed many of the constraints that once shaped it. As execution becomes easier, the real challenge shifts to prioritization, judgment, and building long-term advantage. This talk redefines how to think about strategy in a world where speed is no longer a differentiator, and exposes the gap between teams that truly have a strategy and those that never did. \#\# Audience: * CPO * VPs * Head of Product * Product Director * Product Pros 👉 Join us for an insightful and inspiring meetup packed with practical takeaways. \* The number of seats is limited , so do hurry up and book yours. \*\* Prior to the meetup, you will receive an email containing a QR code, which you will be required to present upon entry to the event. \*\*\*We’re aware of the Tube strikes in London next week, but fortunately, from Wednesday afternoon through Thursday, train services are expected to operate as usual, so there should be no difficulty getting to the meetup.

There are many resources available for guidance on how to write code that is efficient and results in more sustainable software applications, but applying these at scale can be challenging, and often isn’t a priority for busy teams. GitHub have recently released Agentic Workflows, a way of specifying automation tasks in human-readable format to be performed by an AI agent as part of a GitHub Actions workflow. In this talk, Max Mizzi from GitHub's Sustainability team gives an overview of Agentic Workflows, and will demonstrate how they can be used to improve software efficiency through both structured green software rules and autonomous performance engineering. He'll finish by walking through a real-world use-case showing how the technology helped to dramatically reduce the energy consumption - and carbon footprint - of a major website. Come along if you want to learn more about using AI to improve the energy efficiency of your software. Check out the Green Software Brighton [website](https://greensoftwarebrighton.co.uk/) for links to previous talks. Arrive from 18:00 for pizza and drinks. Event will start at 18:30. We always head for a drink and a chat locally afterwards too. --- ***Thank you to Runway East for use of their space to host our events and to Silicon Brighton and the Green Software Foundation for supporting us.***

**AI is becoming part of many documentation workflows, but how do you turn that into a clear, repeatable strategy?** At this month’s meetup, we’ll focus on how to build an AI docs strategy by identifying gaps in your current approach, creating practical playbooks, and using automation to support consistent, scalable documentation.

We will show how to build custom agents with Microsoft Agent Framework. Attendees will learn how to build and custom host agents when Microsoft Foundry is not a viable option.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
