When I started using AI-assisted delivery in my recent project, I expected the biggest challenge would be learning how to get better results from models. Like many developers experimenting with AI, I was focused on the obvious questions: which model produ

I've always had a soft spot for authentication systems. About seven years ago, I started working on auth, and something just clicked. What began as login flows slowly turned into a deeper curiosity about identity, permissions, and how systems decide who g

When people talk about guardrails in AI applications, the conversation usually starts with risk. How do we stop harmful outputs? How do we prevent prompt injection? How do we avoid leaking personal information? Those are valid concerns. But starting there

AI can write code quickly. It can also lock the wrong assumptions into a system with a lot of confidence. In enterprise environments, that confidence is expensive. One fuzzy requirement can turn into a chain of decisions across services, data contracts, s

In the first post, Sunsetting Legacy Angular with Generative AI, I explained how we modernised a large Angular frontend incrementally using: Next.js GraphQL A monorepo Web components Generative AI That approach avoided a risky "big bang" rewrite while let

If you've worked on a long-lived frontend, you already know the story. The app grows, features pile up, deadlines keep coming, and suddenly you're sitting on a mountain of technical debt. That's exactly where we were. We had a large Angular 14 application

Legacy systems are the unglamorous backbone of operations. They're critical, complex and when it comes to modernisation, costly to change. So at a time when every use case is being put under the AI microscope, legacy modernisation has got to be one of the

The shift from Large Language Models (LLMs) as stateless API endpoints to sophisticated, stateful AI agents represents a fundamental architectural change in how intelligent systems are developed and deployed. This blog defines the core components and feat

The vision: pure Temporal, AI-enhanced authentication Over the past few days, I've been immersed in building an authentication system that combines Temporal.io workflows with AI-enhanced security. The goal was ambitious: every operation, from user registr

I hosted two executive roundtables on generative AI and agentic systems in financial services this year, and what struck me wasn't just the pace of change. It was where the hard problems are moving towards. If you're a tech leader responsible for AI outco
