Hey everyone, We’re back with a new edition of the AI Security Engineers Meetup in London on June 23rd with 2 great talks! **Talk #1 - Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for safety** In the rush to build autonomous agents, we face a fundamental tension: the more freedom we give an LLM to solve complex problems, the more likely it is to drift into “stochastic hallucinations” or policy violations. Most safety efforts focus on restricting the model via prompts, which often stifles the very reasoning capabilities required for sophisticated tasks. This talk introduces InsideOut, a design pattern that prioritizes agent autonomy by implementing deterministic checkpoints. Rather than micro-managing the agent’s “thoughts,” the InsideOut architecture allows the agent to navigate freely through a task—provided it periodically “grounds” its progress in structured, verifiable artifacts such as JSON or Markdown. We will walk through a real-world application of this method: an agent designed for setting up and managing cloud infrastructure. The agent is given the autonomy to discuss and decide on Features, Stack Components, Configurations, Cost Estimates, Terraforms, Deployment, and Management. To ensure reliability, each stage requires the generation of a JSON artifact validated against deterministic rules. If a boundary is breached, the agent is triggered to repeat that specific stage until the output is within bounds, preventing error propagation. By drawing a parallel to the concept of a Brownian Bridge versus Brownian Motion, we illustrate how these checkpoints act as “pins” that anchor a random walk. This approach demonstrates how forced artifact crystallization allows an agent to design and deploy complex stacks with high independence and zero “drift.” This session provides a framework for building agents that are more productive because they are safely unconstrained. Speaker: Hossein Kakavand. Hossein did his Ph.D. at Stanford University. He has been with several start up in AI, ML and Distributed Systems, with IPOs on NASDAQ and LSE. He is currently a Co-Founder of Luther Systems focused on solving the Enterprise Operations problem at scale. **Talk #2: Agentic Development Security: Securing the AI Workforce** AI agents are rapidly becoming part of the software development lifecycle, writing code, interacting with tools, and making decisions with increasing autonomy. But as organizations embrace agentic development, a new set of security challenges emerges: How do you trust the tools agents use? How do you prevent dangerous actions? And how do you ensure the code they generate is secure? In this session, we'll unveil and demo Snyk Agentic Development Security, a new approach to securing both AI builders and the AI-powered tools they rely on. You'll see how organizations can secure the agent supply chain by vetting MCP servers, plugins, and external tools before agents interact with them; govern agent behavior through real-time policies that prevent destructive actions with Agent Guard; and ensure trusted output by automatically detecting and fixing vulnerabilities in AI-generated code at the moment of creation. Join us for a live demonstration of how security can keep pace with the rise of autonomous development, enabling teams to innovate confidently while maintaining control, trust, and resilience across their AI workforce. Speaker; Denis Kent - AI Security Engineer at Snyk. Denis is an AI Security Software Engineer at Snyk, building Evo, Snyk's agentic security platform. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- As always, expect great talks, free pizza and drinks, and even better company. 📍 **Where**: Snyk Offices, 24 Eversholt Street, London (Euston tube station is right across the street) 📅 **When**: June 23rd ## Agenda **6:00 PM** – Doors open **6:00 PM – 6:30 PM** – Food & drinks **6:30 PM** – Talks begin **7:30 PM** – Talks end & social time **8:30 PM** – Doors close Looking forward to seeing you there!

The consulting PM with the polished decks, the big tech PM optimising a metric three layers deep, the engineer-turned-PM still half in the codebase—these archetypes shape how we hire, coach, and judge PMs, but they were always more caricature than craft. This month we put them on the table and ask what's still true. Our speakers share their own journeys and talk candidly about how the role is shifting as AI moves from a roadmap item to a collaborator in the work itself. Expect honest stories over tidy frameworks, and a real look at how the role mutates depending on where you sit. **Our speakers:** [Kiran Virdee](https://www.linkedin.com/in/kvirdee/) \- Head of Product @ Accenture UK [Stephen Down](https://www.linkedin.com/in/stephen-down-3b824146/) \- Senior Product Manager @ Channel 4 [Valeria Stromtsova](https://www.linkedin.com/in/lerastromtsova/) \- Product Owner @ myenergi As always we will close our meet-up with a candid discussion and Q&A.

Join us for our 150th #WPLDN event! It's a milestone we're quietly proud of: 150 free, community-driven WordPress-focused events, and we'd love to share this one with you. This month, we're looking at WordPress from two very different but complementary angles. First, Raquel Manriquez asks the question most of us avoid: Who are you really, and why does owning that answer make you a steadier, sharper business owner? Then Paul Halfpenny digs into what WordPress 7.0 and its new Abilities API mean for how we build, and why this quiet change might matter more than the headlines suggest. 📅 **Date:** Thursday, 25 June 2026 ⏰ **Time:** 6:00 PM BST 🎟️ **Cost:** Free (Registration Required) \-\-\- **Session 1: Owning Your Why: The Only Constant in a World of Change** 🤝 **Speaker:** Raquel Manriquez ([PressConf](https://pressconf.events)) The only constant in your business isn't the strategy, the stack, or the team; it's the why underneath them. In this candid session, Raquel moves from the question most of us avoid (who am I, actually?) to the business case for answering it: the boundaries that hold because you know what you're protecting, the decisions that come quickly because you're not weighing other people's opinions of you, and the steadiness of being someone, not just doing things. Raquel is the founder of WonderlandCurious, a tech event consultancy focused on people-first experiences, and previously founded and led the WooCommerce agency Mode Effect for a decade before exiting in 2020. Today, she channels that community experience into PressConf, a conference built around candid, unrecorded conversations among the leaders shaping the WordPress economy. \-\-\- **Session 2: Abilities, not chatbots: how WordPress 7.0 changes everything** 🤝 **Speaker:** Paul Halfpenny ([Filter](https://filter.agency)) WordPress 7.0 shipped on 20 May with the Abilities API in core. Quieter than the real-time collaboration headlines that got pulled, but more consequential. Abilities turn plugin capabilities into something AI assistants and automation tools can discover and invoke, with permissions intact. Paul walks through what changed, what it means for how we build plugins, and what's already running in production across Filter AI, Filter Abilities, and PersonalizeWP, plus a quick aside into whether AI assistants can find your site at all, and how to find out. Paul is the CTO and co-founder of Filter, a UK digital agency. He builds products including PersonalizeWP and Filter AI, leads technology transformation for a major UK brand, and speaks on practical AI, personalisation, tech strategy, and running an agency. \-\-\- **Schedule:** 🔹 **6:00 PM** – Doors Open & Networking 🔹 **6:30 PM** – Welcome & Session 1: Raquel Manriquez 🔹 **7:30 PM** – Short Break & Networking 🔹 **7:45 PM** – Session 2: Paul Halfpenny 🔹 **8:30 PM** – Social & Wrap-Up \-\-\- **📢 RSVP Now!** Don't miss this one. Whether you come for the honest conversation about why you do what you do, or for a clear-eyed look at where WordPress and AI are heading, there's plenty here to take away. Bring your questions for the Q&A, and stick around for the post-event social to raise a glass to 150 events. Secure your free spot today, and we'll see you there! \-\-\- **Venue Information** **The Bridge** is a charity supporting women to make positive choices and encouraging improvements to fitness, health, and wellbeing. The venue features a plant-based café (supplied by Girls Who Grind Coffee) and is just a 5-minute walk from London Bridge Station. \-\-\- **Massive thanks to our sponsors who make these free events possible:** [Filter](https://filter.agency/), [Kinsta](https://kinsta.com/), [Mollie](https://www.mollie.com/gb/integrations/woocommerce), and [PodcasterPlus](https://www.podcasterplus.com/?utm_source=wpldn&utm_medium=banner&utm_campaign=partnership). \-\-\- If you're interested in being a featured speaker at an upcoming event, we'd love to hear from you at [https://wpldn.uk/speak](https://wpldn.uk/speak). **🎥 - Media Release Terms** By attending, you understand and accept that portions of the event may have audio/photo/video-recorded and/or live-streamed and may be used by the organisers.

AI assistants are getting more capable. The question is how we build effective workflows around them. At DevDay London, [Lucy Joyce](https://www.linkedin.com/in/lucy-joyce-597485166/), [Ash Shakrani](https://www.linkedin.com/in/ash-shakrani/) and [Arun Kurian](https://www.linkedin.com/in/arun-mathew-kurian-39b8aa5a/) will explore harness engineering through the lens of a payment integration. From requirements and design through to implementation, they’ll demonstrate why context alone isn’t enough for successful AI-assisted development. Drawing on real-world experience, they’ll show how engineering harnesses, reusable context, standards, and validation workflows help teams move beyond experimentation and build reliable, scalable AI-assisted development practices. **This session will unpack:** 🎯 Why “more context” isn’t the answer on its own 🎯 What engineering harnesses are and how they create reliable feedback loops 🎯 How standards, workflows, and validation reduce AI-generated rework and technical debt 🎯 Practical techniques teams can adopt immediately to improve AI outcomes 🗓️ **Save the Date:** 25th June, 2026 📍 **Location:** Sahaj Software, 1 Quality Court, London, WC2A 1HR 🕕 **Time:** 6:00 PM – 8:00 PM (BST) The evening will feature: 🎤 **One engaging talk** with Q&A 🤝 **Plenty of time for networking** over free pizza and non-alcoholic drinks Don’t miss this chance to learn, connect, and share with fellow tech enthusiasts. 👉 Please click the link below to register. https://sahaj.ai/events/harness-engineering-in-practice-from-requirements-to-implementation/

AI agents are getting better at writing software. That doesn’t mean the software is getting better. As AI systems become more autonomous, engineering teams face a different set of problems: unreliable outputs, untestable workflows, evaluation bottlenecks, and legacy systems that weren’t designed for any of this. At this Future Form session, we’re looking at what happens when agentic systems collide with production engineering reality. **Speakers:** **Ning Lu, VP, Aladdin Financial Engineering, BlackRock** Ning explores the evolving landscape of LLM evaluation. From static benchmarks to LLM-as-judge systems and agent trajectory review, he’ll break down how engineering teams can evaluate systems that don’t behave deterministically. **Katie Roberts, Technical Director & AI Native Specialist, Nearform** Katie will show how AI-native engineering can be applied inside mature brownfield systems. Using patterns like the Strangler Fig approach, she’ll explore how to isolate risk, generate tests for undocumented code, and evolve legacy architectures without full rewrites. If you’re working with AI agents, legacy systems, or production engineering workflows, this session is for you. Pizza, drinks, and practical AI insights included.

This June we're at FundApps offices in HYLO, Bunhill Row. Chris Simon's back in town, and will be joining us to talk about streams and queues; plus Tiago Sousa from SteelEye will be talking about the work they're doing around using AI in comms surveillance. Our hosts at FundApps will be providing drinks and snacks, and there will be plenty of time to chat beforehand and in the pub afterwards. **Chris Simon: It's like 10,000 streams when what you need is a queue** *🎶🎵 A new dev team adopted E-D-A* *Got head of line blocking, on their very first day* *Isn't it ironic, don't you think 🎶🎵* The last few years have seen widespread adoption of Event-Driven Architecture, supported by DDD practices such as event storming. But what does that orange sticky note become when we start implementing our design? Common implementation choices include event sourcing, streaming platforms like Kafka and queuing systems like RabbitMQ. Unfortunately not every orange sticky note has the same operational needs, and many teams remain confused about the differences between these options, resulting in the selection of the wrong paradigm for their needs. This can lead to unnecessary complexity & operational challenges such as head of line blocking, dropped messages, challenges dealing with failed messages, difficulty with adaptive scaling and inadvertently increasing coupling between services. In this talk we'll bring that orange sticky note into the runtime of our system. We’ll start with a deep dive into the similarities and differences between event streaming platforms such as Kafka and queueing systems such as RabbitMq, Azure Service Bus & AWS SNS/SQS. We’ll then look at ways to assess your orange sticky notes to work out which messaging and persistence paradigms suit each one, helping you build more resilient, scalable and loosely coupled event-driven architectures. **Tiago Sousa: AI in Comms Surveillance** In this talk, Tiago shares what it's actually like to build AI for communications surveillance at SteelEye. Financial firms are required to monitor and flag communications for compliance, but making AI work reliably in that context is harder than it sounds. He'll walk through real examples from the trenches: what worked, what didn't, and what he'd do differently. **Tiago Sousa** is a Staff Data Engineer and AI Lead at SteelEye - a platform that helps financial firms monitor and flag communications and trades to stay compliant with regulations. He's spent the last five years building the data and AI systems that make that work. Before that, he did research in bioinformatics, which means he came into fintech from an unusual angle and has the scars to prove it. He's based in Braga, Portugal.

**Hello There! And welcome to our June Gophers @ Meta event!** It's immensely exciting that we'll be visiting Meta for our June event, but with great big office comes great responsibility, so it is **CRITICAL THAT YOU HEED THESE ENTRY REQUIREMENTS!** * You MUST bring Government Issued Photo ID with you, matching the name with which you sign up to this event * You MUST complete the NDA that will be emailed to you in advance of the event, before arrival * You MUST be over 18 years old * You MUST NOT record when inside the venue * You MUST wear the lanyard provided to you on the night at all times And needless to say, if you satisfy all of those criteria and manage to make it through security without being tackled, you MUST have a lovely time otherwise you know I'll be giving you a hard stare. A massive thank you to Meta for hosting! See you all there! ==== 📓 **Agenda**📓 ===== (Certain timings and orders may be subject to change) **5:30pm onwards:** Sign-In, Food & Refreshments **6:55pm:** Introduction **7:00pm:** 🗣️ **Jon Bodner: Testing Go: From the Basics to synctest** Testing is fundamental to software engineering and as a language focused on software engineering, Go includes a wide variety of tools to ensure your code is working as expected. I’ll walk through the basics of testing in Go, and then cover some of the more advanced tools: benchmarking, fuzzing, and the new synctest package. **7:40pm:** Raffle and Break **8:00pm: 🗣️** **Oleg Obleukhov: Time @ Meta** Discover how Meta uses Go to build PTP and NTP - open-source, highly efficient time synchronization systems that achieve nanoseconds precision. **8:30pm:** Break **8:40pm: 🗣️** **Simon Emms: Failure Happens. Your Code Shouldn't Care** As Gophers, we expect our code to be retried, restarted and run more than once. The challenge is making that safe and maintainable without layers of defensive plumbing. Temporal lets us write reliable workflows in Go that automatically recover from crashes and restarts, while still looking and feeling like normal Go code. In this talk, I’ll explain how it works and prove it with a live demo that treats failure as just another code path. **9:10pm:** Raffle Winners! **9:30pm:** Pub / Socialize ==== 🎉 **Prizes & Discounts!** 🎉 ===== **JetBrains Raffle!** \- We have 3 free JetBrains Product licenses to give away to some of our lucky attendees\! **Ardan Labs Raffle!** \- We're giving away one course license for Ardan Labs' Ultimate Go Bundle\! **Manning Publications Raffle!** \- We're giving away 4 free Go e\-books\! **45% Manning Publications Discount** \- a massive discount provided by the fine people at Manning\!

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

*We'll update this with the specific topic(s) once they're set for the month.* A relaxed, community-driven Unity GameDev meetup. No strict agenda — just developers getting together to talk shop, share projects, and exchange ideas. Some topics that may come up (based on attendee interest): * Frame Debugger & performance tooling * Addressables & additive scene workflows * Input System, localization, responsive UI * AI integration approaches * DevOps & LiveOps experiences * Full lifecycle: idea → cross-platform publishing * Favorite Asset Store tools and hidden gems * Weird Unity quirks we've all run into Nothing is locked in. Bring a project if you'd like, bring a question, bring a lesson learned — or just come hang out and meet other developers. All skill levels welcome. Food and drinks provided.

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
