Full-stack architecture
Designs from the user interface down to data storage, documented and verifiable.
Built fast is a long way from built to last.
I am a freelance lead developer and software architect. For more than 15 years I have worked full stack, focusing on architecture, IT security and accessibility.
I use agentic coding and AI tools productively and guide teams in adopting them. The result: systems with clear architecture, reliable tests and clean reviews – pragmatic, collaborative and agile.
