John Hartnup - Senior Software Engineer @ Wealth Wizards

Almost every language's guide warns us that `0.1 + 0.2` doesn't equal `0.3. But when did you last think about the fundamental reasons for this? And what can you do about it? This presentation tackles floating point representation - that perennial source of gotchas that even seasoned developers occasionally stumble over. We'll examine the mathematical foundations, implementation details, and practical implications of how computers represent and manipulate decimal numbers. Whether you're a veteran programmer who's encountered floating point quirks throughout your career, or a developer starting their journey, this talk offers valuable insights. We'll cover the basics of the IEEE 754 standard, precision limitations, and strategies for avoiding or mitigating the imprecision inherent in floats.

Oziri Emeka - Senior Developer

I'll be speaking on AI and machine learning, focusing first on what it takes to train and build an in-house AI model. Drawing from my personal experience, I’ll walk through the practical realities such as resource constraints, technical challenges, and the skills needed, as well as how AI/ML development intersects with academic research. Alongside this, I’ll discuss how lightweight, on-device learning techniques fit into the larger picture of AI/ML federation, especially in the context of privacy-preserving machine learning. I’ll explain the mechanics of building models that avoid transmitting raw data, instead sharing encoded parameters or gradient arrays. This approach makes it significantly harder for external actors to intercept or misuse sensitive business or personal information.

"Generalist - adaptable intelligence": Here's what I've learned after 15+ years in tech: the person who makes the biggest difference is often not the deepest expert. It is the person who can jump into a new API or codebase and make sense of it quickly, explain technical decisions in plain English, and spot the connections between problems that appear to be unrelated. Tech changes every 18 months... your ability to learn and adapt matters more than what you already know.

"Move Fast and Build Things: A Non-Technical Guide to AI Agents" is a talk for anyone who's ever needed a single feature locked behind an expensive subscription or found themselves waiting weeks for a simple proof of concept. While AI agents might not quite live up to all the hype, they are genuinely reshaping how quickly we can design and deliver software. In this session, I’ll demonstrate how to take an idea and turn it into a working product within a matter of hours, share a practical process to follow, point out common pitfalls, and discuss the limitations of the technology. Whether you're a technical founder or simply someone with a good idea, this talk will show you how AI agents can help you build things faster and more efficiently.

Ben Paddock

Ben Paddock, a senior developer at The Economist and a speaker on mental health in the tech industry, explores the challenges of maintaining mental wellbeing in the tech world. Working in tech can be mentally demanding. In this talk, we’ll examine the factors that influence mental wellbeing at work and discuss practical steps employers and colleagues can take to provide support.

Mike van Oorschot

Mike van Oorschot, a senior consultant at Codurance and a speaker on Test Driven Development (TDD), explores its concepts, benefits, and approaches. Join Mike as he delves into TDD: what it is, what it isn’t, its brief history, core concepts, and the benefits it can bring. He will also compare and contrast the two main styles of TDD, inside out and outside in, discussing their pros, cons, and when to use each approach.
