GDG Cloud London is thrilled to be partnering with Skyscanner for a deep dive into the world of AI applications in Production. This meet-up is a unique opportunity to connect with fellow AI enthusiasts, industry practitioners, and researchers in a dynamic and interactive setting. We are going to have some pizza and networking at the end! Don't miss out, RSVP now!AGENDA 18:00 - Doors Open & Check-ins 18:30 - Welcome & Intro 18:40 - Ellen Muller - Vectors in the Newsroom: Building Smarter Image Search at the Guardian. When a photo editor searches our image management system for "protest" at 6pm on a deadline, they can't afford to get zero results because the images were captioned "demonstration." Traditional keyword search has no way to know those mean the same thing - and for an archive with inconsistent metadata, that gap matters. This talk is about how we added semantic search to the Grid (the Guardian's open source image management system) using embeddings and vector similarity. We'll dig into how vector spaces let you encode meaning rather than just text, and the practical choices (and mistakes) involved in shipping this into a real production system. 19:15 - Bruno Ripa - Technical challenges of AI adoption in Healthcare Deploying AI in healthcare requires solving a shifting equation: balancing high-fidelity clinical utility against rigorous data sovereignty mandates and punishing infrastructure costs. This talk breaks down how our company navigates this fluid landscape daily. We will cover where we use AI in our stack, how localised data compliance continuously reshapes our engineering choices, and the concrete technical hurdles we encounter along the way. Rather than showcasing a finalised architecture, we will focus on the ongoing design decisions and trade-offs required to keep our product secure, reliable, and compliant, all while aggressively optimising compute and operational costs—proving that surviving the mutating challenges of healthcare AI is a continuous process of lean execution. 20:00 - Pizza & Networking Agenda --- Speakers Bruno Ripa - Dyad (Senior AI Engineer) Ellen Muller - The Guardian (Software Engineer) Hosted By Amanda Cavallaro, GDG Organizer I'm an Aikidoka, Developer Advocate, Software Developer, Google Developers Expert, Linkedin Learning Author and a Full Stack Web Development Specialist.

Not just theory. Not "use ChatGPT to write faster." A real, repeatable system — built live, around an actual EU brand. You'll watch the full cycle work end to end, then walk out ready to run it on your own business tomorrow. Here's what you'll walk away with: 🎯 Find — Pinpoint your ideal customers and pull a clean, structured lead list from sources hiding in plain sight. AI does the heavy lifting. ⚡ Qualify — Turn your gut instinct into a scoring system the AI runs at scale, so you only chase leads worth chasing. ✉️ Convert — Write outreach that goes way beyond {{name}} — then sequence follow-ups that hold the thread and pull replies. By the end, you won't just understand AI outreach. You'll have designed the engine. Perfect for SME owners, founders, consultants, employees and students who want a system that works — not another AI demo.

Hi folks! Welcome to our July Cloud Native London meetup! Join us to hear from our two speakers and network with your fellow techies over pizza and drinks, or alternatively chat and following along on Youtube or LinkedIn! 6:00 Pizza and drinks 6:30 Welcome 6:45 Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems) 7:15 Putting Open GitOps to the test (Steve Fenton, Octopus Deploy) 7:45 Wrap up See you there! Cheryl (@oicheryl) **Putting Open GitOps to the test (Steve Fenton, Octopus Deploy)** The Open GitOps principles sound plausible, but the world is full of surprising realities. Join Steve Fenton and explore the GitOps research to see whether GitOps delivers on its promises, based on an analysis of over 600 perspectives from roles like DevOps engineers, developers, platform engineers, and cloud infrastructure engineers. *Steve Fenton researches the socio-technical systems behind software delivery; how organizations, people, and technology actually work together (or don’t). At Octopus Deploy, he explores GitOps, Platform Engineering, Continuous Delivery, and compliance through a lens shaped by punk history, psychology, and the kind of genre fiction that asks uncomfortable questions about systems and society.* *He’s an eight-time Microsoft MVP (DevOps), a DORA Community Guide, a CD Foundation Governing Board member, and a contributor to the CNCF Platform Engineering Community Group. He’s written books on TypeScript, Octopus Deploy, and Web Operations Monitoring, and occasionally writes horror fiction.* *https://www.linkedin.com/in/stevefenton/* *https://mastodon.social/@stevefenton* *https://bsky.app/profile/stevefenton.co.uk* **Architecting Safe Autonomy: High-Stakes Autonomous Agents Need Deterministic Checkpoints for Safety (Hossein Kakavand, Luther Systems)** The more freedom we give an autonomous agent, the more it drifts into hallucinations or policy violations, yet clamping it down with prompts kills the reasoning we want. Think Brownian Motion versus a Brownian Bridge: a random walk wanders anywhere, but pin it at fixed points and it moves freely between them while always landing where it must. Deterministic checkpoints are those pins. InsideOut applies this to infrastructure. It works with the user to shape a feature set, stack, config, Terraform and cost estimates, then deploys and manages the infrastructure in real time for monitoring, alerts and changes. Each stage must produce a structured artifact validated against fixed rules, and if a check fails only that stage repeats, catching errors before they propagate. High-stakes actions stay locked down by design: the agent can request a deploy by presenting a button, but never holds the cloud keys itself. The result is an agent that is more productive precisely because it is safely unconstrained. *Hossein Kakavand holds a Ph.D. from 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. @HosseinKavavand* ***Check out [https://www.oicheryl.com/cloudnativelondon](https://www.oicheryl.com/cloudnativelondon) if you're interested in speaking or sponsoring.***

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:** 2nd July, 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/

***Enter the live meeting room here: [https://discord.gg/5wgxtr4c2u](https://discord.gg/5wgxtr4c2u)*** ***Download the engine here: [https://www.unrealengine.com/en-US/download](https://www.unrealengine.com/en-US/download)*** Welcome to the **Unreal Engine Workshop!** In each session we'll tackle essential game design discussions, then transition into hands-on project creation. Participants will build and expand their skills continuously as we explore every aspect of game development. From basic blueprints and interactive mechanics, to advanced rigging, animation, environment design, and lighting, we'll work our way up to creating small complete games. We encourage experimentation and peer teaching, so whether you're a beginner or experienced developer looking to deepen your expertise, our sessions provide a supportive environment to learn, create, and innovate together in Unreal Engine 5.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. 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.

Whether you've never done improv before, or you've done it for so long you were quoted in *Truth in Comedy*, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup**! The idea behind improvised comedy is to create entire scenes from scratch. A suggestion is taken from the audience and laughter is built on the spot. This can be done in game form, like *Whose Line Is It Anyway, Make Some Noise,* or *Wild 'n Out*; it can also be done in a longer way, to tell a complicated story, like *TJ & Dave*. Our meetup, which is central Ohio's longest running (and FREE!) weekly comedy event, brings the games for you to play in a safe, supportive, and compassionate environment. Afterward, many members will hang out in *Gresso's* itself and get to know each other. Not only is this a lot of fun, but you get to work on thinking faster on your feet, your public speaking, plus it's an excellent way to meet new people and build relationships that will last a lifetime, and you do that while laughing your butt off! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "*Yes, And*" that you'll have a blast!
