About

Senior Full Stack Developer with 18 years of commercial experience, including 10+ years of remote work for North American clients. I specialize in headless Next.js architectures, TypeScript/Node.js and Go APIs, and edge/cloud infrastructure for high-traffic publishing products.

I've been part of technical decision-making, code reviews and supervising other developers, and I'm currently building AI-driven design-to-code and testing workflows with Anthropic Claude and the Model Context Protocol (MCP).
