Retrieval-Augmented Generation (RAG) is the gold standard for grounding LLMs in proprietary enterprise data. However, the journey from a flashy proof-of-concept to a reliable, secure production system is fraught with complexity. This talk bridges the gap between rapid prototyping and rigorous engineering. We will begin by exploring the actual merit of “vibe-coding”—using AI-assisted, rapid prototyping to build compelling demo apps that secure client buy-in and validate use cases. Once the demo is sold, the real work begins. We will navigate the architectural decision matrix, comparing the trade-offs of off-the-shelf products, cloud-managed services, and fully custom-built RAG solutions. Diving into the technical pipeline, we will cover modern ingestion strategies like agentic chunking and sophisticated retrieval methods, including re-ranking and GraphRAG, to overcome the limitations of simple vector search. We will detail the essential role of telemetry and LLM-as-a-Judge evaluation frameworks in ensuring sustained performance, faithfulness, and relevancy. Join us to learn how to transition from impressive demos to robust solutions that deliver measurable business value. Our Speaker, **[Dr. Enrico Fonda](https://www.linkedin.com/in/enricofonda/)** is a data scientist with a background in physics.

**About the London Software Guild** ​The London Software Guild gathers developers, architects, and teams across London who care deeply about the craft of building great software. No fluff, no vendor pitches — just people who take the work seriously, sharing what they've learned the hard way. *** ## ​**Tonight's Speakers** ## ​**🎤 Kieran — Founding Engineer, Demand-Genius** ​Kieran is a founding engineer at Demand-Genius, working to close the gap between how humans and machines perceive your brand versus reality. Background in electrical & electronic engineering, previously working on real-time payments systems, high-scale distributed dynamic rules engines, and reverse proxies. Third Start-Up/Scale-Up (because I'm dumb and have never learnt my lesson). ​ **Talk: The Statistical (Un)Certainty That Our AI Co-Founder Ruins Everything** ​We have handed the most powerful text prediction machines ever built the keys to our codebases. They write code that is statistically likely to be correct. But "statistically likely" and "correct" are not the same thing. As we move toward autonomous multi-agent systems writing production code at machine speed, that gap becomes the central engineering problem of our time. ​Code is not text. It is a formal, deterministic, mathematical structure that happens to be serialised as text. Every tool in the agentic coding stack — retrieval, editing, version control, coordination — treats it as text. ​This talk argues that the answer isn't better frontier models. It's better systems around models. Specifically, the engineering disciplines we've used for a century to control uncertain systems — feedback loops, formal verification, dependency analysis, and control theory — are the missing layer between "AI can write code" and "AI can write code you can trust." *** ## ​**🎤 Andy Roberts — Senior Engineering Leader** ​Andy Roberts is a senior engineering leader with 25+ years of experience — the kind where you've actually written the code, run the teams, and been in the room when things went wrong at scale. Previously Head of EMEA Enterprise Solutions at Apollo GraphQL, where he helped companies like [Booking.com](https://booking.com/), PayPal, and The New York Times stop arguing about their APIs. Before that, Head of API Engineering at RS Components, wrangling 11 teams. Has strong opinions about federated architecture and isn't afraid to use them. ​ **Talk: Built for Browsers, Billed by Tokens** *Your microservices solved for latency. AI agents are solving for context. Nobody told your APIs.* ​Every era of software development has been defined by a constraint that reshaped architecture. In the database era we optimised for round trips. In the web era we obsessed over latency. Mobile forced us to think about bandwidth and battery. Each shift required new instincts, new patterns, new defaults. We're in the middle of another one. ​The AI era introduces a new constraint: context. Language models have finite working memory, and every API response your services return goes into it. The kitchen-sink response payloads that work fine for browsers are quietly making your AI agents more expensive and less capable — and the cost is almost entirely invisible in your existing dashboards. ​This talk maps the constraint transition from latency to context, shows what it means for the microservice APIs you have today, and offers five concrete things you can do about it without touching a line of existing backend code.

​Join us for the 25th London PyTorch Meetup! 🔥 ​We have our first speaker confirmed: **Peter Romov** – Open Source Contributor, 2. PyTorch/Opacus Autoresearch for Discovering State-of-the-Art LLM Adversarial Attacks ​More speakers to be announced.

Hi Architects, Welcome to our the second AWS London Well-Architected User Group Meetup!!! 🥳🥳🥳 Due to the huge demand we saw for our inaugural meetup we have gone bigger with a new venue. Dragon Hall Trust, 17 Stukeley Street, London WC2B 5LT The AWS London Well-Architected Meetup is the latest chapter in the most popular AWS Meetup group globally. At each meetup we cover off various pillars of AWS best-practice in detail including insights from industry leaders that specialise in the Well-Architected Framework. We'll be announcing more speakers and topics over the coming weeks. **Speakers** * **The Philosophy Behind Well-Architected** **Philip Fitzsimons (Fitz)** \- Ex\-AWS \- Co\-authored the AWS Well\-Architected Framework\. The Well-Architected Framework started at AWS but has since been adopted by every major cloud vendor and beyond. Why did it resonate so widely? In this session, Fitz, who led the Well-Architected initiative at AWS from the beginning, explores the philosophy behind the framework, how it was intended to shape architectural thinking, and the mistakes teams commonly make when applying it. Drawing on lessons from seeing thousands of real architectures, he will explain how to approach Well-Architected reviews in a way that actually improves systems rather than just generating checklists. * **Running your first Well-Architected Review: A Live Walkthrough** **James Harding** \- Technical CSM \- Green Custard Curious about how a Well-Architected Review works in practice? In this session we'll run a live walkthrough using the AWS Well-Architected Tool, showing how to define a workload, answer the review questions, identify High Risk Issues and move on to an actionable improvement plan. * **Building Your Infrastructure: "Self-Hosted vs. Managed"** **Mykola Boiko -** Backend Developer - Ultralytics What does it really cost to build and operate your own infrastructure? Mykola Boiko shares real-world lessons from scaling a globally distributed AI platform using self-hosted infrastructure before gradually migrating services to AWS. Through stories of building replication, caching, observability, and multi-region reliability from scratch, the session reveals the hidden operational complexity and costs behind running everything yourself. The journey highlights key principles of the AWS Well-Architected Framework including Reliability, Performance Efficiency, Operational Excellence, and Cost Optimisation and shows why managed cloud services can dramatically reduce operational burden while improving scalability and resilience. More speakers to be announced soon. So come join us at 7pm for a 7.30pm start, including drinks, snacks and friendly networking after our talks :-) \*\*\*NB: No entry to the building after 7.30pm.\*\*\*

It’s been a while since we caught up. Let’s get together and discover some London Wine. Looking forward to seeing you 😊

We playtest all sorts of games - strategic, silly, creative, or whatever. Some games are almost done. Some are very early ideas. We test anything that will fit into 90 minutes. You don't need to bring a game - we always love to have new playtesters! Please let us know in the comments when you plan to arrive/leave and whether you are bringing a game or not. This helps us to plan the day better. The schedule is: 10am onwards - gathering, chatting 11am sharp - playing for 90 min ('slot 1') 12:30ish - break for food/chat 1pm sharp - playing for 90 min ('slot 2') 2:30ish - break for food/chat 3pm sharp - playing for 90 min ('slot 3') 4:30ish - finish up Often, we might hang around afterwards, to play some already-published games. We are strict on timings, so please try to arrive a few minutes before the session to limit disruption. You can just come for part of the day if you wish. The reason we have fixed timings for the 3 'slots' is to make it easier for folk to do so. Designers of all levels of experience are welcome! But if it's your first time, we ask that you don't bring a game and just spend some time learning how the group works. The group works based on reciprocation. If you expect to test your own game, make sure stay for long enough to play other games. As a general rule of thumb, you can expect to play one of your own games every third 90-minute session. So if you stay a whole day (3 sessions), you can expect to have one session to play your game(s). A good rule of thumb is that if you come all day, you will have one 90 minute session with two other playtesters in which to test your own games. It is sometimes possible to test games with more players. If your game requires 4 or more, please note that as standard you will be allocated half of a session (45 minutes). Pre-covid, we were getting unmanageable. As a result, we may have to limit attendees. This is a free-to-use venue, and we have to be mindful that other folk want to use the same space. Please note: This is an adults only event. We look forward to seeing you!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
