**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.

¡Bienvenidos! Welcome! *Etc Etcetera es un intercambio de conversación totalmente gratis, donde puedes practicar inglés y español con hablantes nativos, y conocer unos amigos nuevos.* **Come and join us at ‘Etc Etcétera’ this coming week, our Spanish/English language and culture exchange based here in Peckham.

**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

**Improving Office in Franklinton** Physical location: Improving Office 330 Rush Alley Suite #150 Columbus, OH 43215 Schedule: 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages. 6:30 to 8:00 pm. Main meeting and presentation(s). Topic: Type Annotations with John Cassidy We meet on the last Monday of each Month. Presentations are given by members and friends of this group. If you would like to do a presentation (small or large) on a python topic, please contact Central OH Python at centralohpython@gmail.com

**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** [https://youtube.com/live/fD2cYeKp_UU?feature=share](https://youtube.com/live/fD2cYeKp_UU?feature=share)

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
