About
Full Stack Developer with 26 years of software engineering experience, building AI-powered web products end to end
in Next.js, React, TypeScript and Node.js on PostgreSQL. I integrate the OpenAI API and the Vercel AI SDK into real
product features, and pair model output with rule-based logic where deterministic behaviour matters. I build Supabase
and PostgreSQL backends with secure authentication, Row Level Security and least-privilege access for sensitive
personal data, deploy on Vercel and AWS, and ship responsive interfaces that stay maintainable as scope grows.
Available long-term on a part-time basis and comfortable delivering a working first version quickly.
