Software teams trust, with AI that makes them faster.
Senior Full Stack Developer with a strong record of modernising legacy systems, removing rework, and growing engineering teams across banking, the public sector, and fintech. I also keep a hands on AI practice, building agents and Spec Driven Development workflows that speed up delivery without giving up quality.
AI Agents and SDD Workflows
I design agent systems and Spec Driven Development workflows that take over manual, repetitive work. Then I coach the whole team so they get real value from them.
End to End Delivery
From precise Angular and React micro frontends to resilient Spring Boot and Node.js services, with clean architecture, WCAG AA accessibility, and automated tests.
Architecture and Mentorship
Architecture reviews, structured code reviews, knowledge transfer sessions, and one on one coaching that cut rework and make team delivery more consistent.
