Built for developers, Figma's Dev Mode gives you the power to easily inspect designs and translate them into code—without changing the design file. Headquartered in San Francisco, in 2020 Figma opened its EMEA HQ in London. We’re a team of makers who celebrate our differences and share a passion for our community. Our London based engineering team is growing quickly and working on some of Figma's top company priorities. 🤝 **Want to support our community?** We’re looking for venue partners and sponsors for future meetups. Let’s discuss collaboration — [contact us](https://forms.gle/zWYxsanfbhV64dEr5)! **🕑 Event Schedule** * 18:00 - Doors open - snacks, beer, socialization * 18:50 - Opening notes * 19:00 - **The Lost Art of Debugging: Why Your Browser is Smarter than AI - [Abdullah Ola Mudathir](https://www.linkedin.com/in/cruxcodes/)** * 19:25 - **Why Your Marketing Scripts and Cookie Banners Are Ruining Your Lighthouse Scores - [Christopher Burns](https://www.linkedin.com/in/burnedchris/)** * **19:50 - Networking, Open Mic Lightning Talks** * Mingle until 21:00 pm 🗣️ **Talks** ➡️ **The Lost Art of Debugging: Why Your Browser is Smarter than AI - [Abdullah Ola Mudathir](https://www.linkedin.com/in/cruxcodes/)** *The easiest thing to do is often what causes hours of debugging down the line. With LLMs becoming increasingly normalized in the industry, an overreliance on them can allow bugs to slip through the cracks.* *In this talk, I'll demonstrate a practical debugging workflow: Debug first. Prompt second. I'll show how browser DevTools reveal what's actually happening faster than any AI can guess.* *You'll learn:* * *Essential DevTools features that improve your bug-fixing prowess* * *When to reach for your browser and when AI can actually help* * *The almost forgotten art of breakpoints and strategic console messages* *AI in your codebase represents growth, but understanding your runtime state represents mastery. This talk is about balancing both and knowing which tool to reach for first.* ➡️ **Why Your Marketing Scripts and Cookie Banners Are Ruining Your Lighthouse Scores - [Christopher Burns](https://www.linkedin.com/in/burnedchris/)** *Most marketing scripts and cookie banners run on the critical path. They block the main thread, delay first paint, and inject third-party code before the page is interactive.* *Consent managers often make this worse by synchronously loading vendors, mutating the DOM repeatedly, and re-hydrating UI after page load. The result is slower LCP, higher TBT, and unstable CLS.* *The fix is not fewer scripts, it is better orchestration. Treat consent as infrastructure, load vendors after intent, and keep compliance off the critical path.* — **👍 Code of Conduct** By registering for this event you agree to comply with our [CoC](https://gitnation.com/coc) **📩 Contact** events@gitnation.org https://twitter.com/ReactAdvanced http://youtube.com/ReactConferences https://bsky.app/profile/reactadvanced.gitnation.org

## Details Welcome to the DevSecOps London Gathering February Event on Wednesday 19 Feb in collaboration with London DevOps! We bring you two amazing talks, as well as the usual conversations, pizza and beer! 📍 **Hosted at Autogen AI, Pentonville Road, London** 📅 **Wednesday, 19 February** 🕕 **6:00–8:00 PM** ## Talk 1 **Abstract:** Concrete CMS, a popular open-source content management system, contains a critical flaw in its file upload functionality that can be exploited in two distinct ways. This talk demonstrates how a single upload can lead to a Server-Side Request Forgery (SSRF), allowing access to internal cloud resources, and a double race condition that enables Remote Code Execution (RCE) via a malicious backdoor. We’ll walk through the exploitation process, show how existing protections can be bypassed, and highlight practical steps to secure file upload mechanisms in real-world applications. ## Talk 2 **Abstract** Treat authentication as a production-critical system with its own failure modes and operational risks. In this talk, I break down real-world auth incidents involving JWKS rotation errors, refresh token storms, clock drift, and session store outages. I show how to define SLIs and SLOs that measure user impact and how to build monitoring and alerting that expose real reliability problems. I demonstrate practical guardrails such as token caching, exponential backoff with jitter, circuit breakers, and feature-flagged degraded modes. Finally, I walk through an incident runbook that helps teams diagnose, mitigate, and recover from authentication failures safely and quickly.

🏎️ **If you’re not automating yet… you probably are.** Be honest: how much of your job are you already secretly automating, and how much of it is just automation in disguise? In this session, **[Ellis Pratt](https://www.linkedin.com/in/ellispratt/)**, director of **[Cherryleaf](https://www.cherryleaf.com/)**, will take a clear, no-hype look at automation in technical communication. He’ll rewind to where things stood just over a year ago, then discuss what’s changed since. We’ll explore how automation shows up across the technical writing lifecycle, and common pitfalls that come with it. Finally, we’ll look ahead. What does increasing automation really mean for our careers as technical writers and documentarians? Join us for an honest, practical conversation about what to automate, what not to, and how to stay relevant as the tools keep changing. **📣 This event is aimed at technical writers and those working in closely related roles. The discussion will focus on automation and AI specifically in the context of technical documentation and technical content workflows.** **When:** Thursday 19 February, from 6.30pm **Where:** The Yellow Room @ Remark! 18 Leather Lane, EC1N 7SU **What:** 18.30 - 19.00 Arrival 19.00 - 19.45 Presentation 19.45 - 20.00 Short break 20.00 - 20.45 Presentation 20.45 - 21.30 Networking *All times are approximate.* **Photos:** Note that the organizers will take some photos for the WTD group.

You can expect a friendly introduction to the sport, but in all honesty you will dive in at the deep end to learn UWR. Please bring swimwear and an open mind and expectation to have fun. We can lend an UWR hat, snorkle, mask and fins. Although if you have them already it is better to bring your own. Expect to swim, dive to 4m depth, hold your breath longer than you thought you could, be involved in drills and games. It is full contact and you will be wrestling other players to take the ball and pass to your team or score a goal. Please get on touch with questions or intent to attend prior to session so that we can support with kit etc.

NOTE: This meetup is more technical than our normal subjects! Everyone is welcome to join but the content will be designed for developers and engineering leaders. Shaping our future with AI. Creating opportunity through AI fluency, connection and community. No jargon. No hype. No confusing terminology. **Join us for our next in-person meetup in London on Thursday February 19th.** Our theme for this meetup is **AI Coding the right way.** We'll be joined by Daniel Jones (AI Consultant, re:cinq) who has taught over 100 developers how to get the most of AI tools. Then we welcome a panel of engineering leaders to discuss the lessons they have learned on getting the best from their teams with new tools! **Where and When?** * Thursday, February 19th * Doors open at 18:00 * Talks start at 19:00 * Tessl HQ, 210 Pentonville Rd, London N1 9JY, UK **Talk: Agentic Coding For 100 Developers** (Daniel Jones) How has a $3b Stockholm SaaS company transitioned 100 developers to AI-native development over a few weeks? Deejay shares how he helped Odevo with exactly this, but the answer might be more than you expect - it involves just as much discovery and psychology and it does training. Learn about the social and business pre-requisites for such a transformation, the syllabus that enables developers to use multi-agent workflows, and how 'one-and-done' training is insufficient for this type of behavioural change. **About Deejay:** Deejay is an AI Consultant at re:cinq, and has over a decade of experience in assisting organisations with tech transformation. He's been a developer, manager, entrepreneur, keynote speaker, father, bassist, martial arts instructor, games developer, and wearer of a rather silly moustache. **Expert Panel: Leading Dev Teams Through AI Adoptions** There are no right answers but there is certainly a lot of talk about when it comes to adopting AI coding tools in the right way. This expert panel will share the lessons they've learnt so far and what's working for their teams. * Norberto Lopes, VP Engineering, Incident.io * Corey Leigh Latislaw, Head of Engineering at JustEat Takeaway * Daniel Jones, AI Consultant, re:cinq **About Norberto** Norberto is focussed on the intersection of building technology and how humans behave and work together. Currently VP Engineering at Incident.io, Norberto has enjoyed a varied career from startups to large companies. Growing teams across IT, product delivery, security, data infrastructure, and infrastructure. Read Norberto's excellent blog here: [nlopes.dev](https://nlopes.dev/) **About Corey** Corey Leigh Latislaw is Head of Groceries and New Verticals at JustEat Takeaway and previously led AI adoption alongside her day job at Trainline and Kin + Carta. She believes the human capacity for creativity is key to thriving in the age of AI. **Code of Conduct** This event has a code of conduct that you can [review here.](https://aifortherestofus.live/code-of-conduct) **Providing Your Name and Email** To register for this event you'll be asked to provide your full name and email address. This is a requirement for building security so please provide your real name and email address. After the event you will be automatically subscribed to event updates from AI for the rest of us and AI Native Dev. You can unsubscribe at any time.

**Quick heads up: RSVPing here helps us gauge interest, but you’ll need to complete your registration on AI Camp to save your spot and get event updates. It only takes a minute. Sign up [here](https://www.aicamp.ai/event/eventdetails/W2026021910) and you’re all** **set**. **[https://www.aicamp.ai/event/eventdetails/W2026021910](https://www.aicamp.ai/event/eventdetails/W2026021910)** AI is already part of how developers work: Coding assistants. Autonomous agents. Background tasks. PR reviews. But in most companies, AI usage is either completely ungoverned or quietly blocked. This meetup is for developers who want to understand what AI governance actually means in practice, without turning their workflow into a compliance nightmare. We’ll focus on how teams are introducing guardrails that protect source code, credentials, and infrastructure while still letting developers move fast. No policy decks. No buzzwords. Just real examples of how AI agents are being used safely inside modern dev environments. **You’ll walk away with:** \- A clear understanding of what AI governance actually means for developers\, not just security teams \- Insight into why AI agents need different permissions than humans and where most teams get this wrong \- Practical examples of how guardrails can speed teams up instead of slowing them down \- A simple mental model you can apply whether you’re experimenting with AI locally or rolling it out across a team **Who this is for:** \- Beginner → intermediate software developers \- Platform engineers and DevOps folks supporting dev teams \- Anyone using \(or wanting to use\) AI tools beyond simple autocomplete **Agenda:** \* 6:00pm\~6:30pm: Checkin, Food 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

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
