Occasional writing on software architecture, engineering practices, and the tools that are changing how we build. These are practitioner notes, not thought leadership — things I've learned, built, or figured out the hard way.
What my children accidentally taught me about prompt engineering. Ambiguous prompts, context, chain-of-thought reasoning, and why feedback shapes behaviour — whether the system is an AI model or a three-year-old.
Integrating NaPTAN, ATCO, GTFS, TransXChange, SIRI. Messy data, conflicting standards, domain-driven design in practice.
A practitioner's honest take on choosing architectural styles. When a monolith is the right call. When to introduce event-driven patterns. The real cost of distributed systems. Drawing on experience of using different styles for different products.
