Profile

From the terminal to the interface — one person, the whole stack.

Senior full-stack engineer with ~25 years hands-on across software, design, databases and content. I ship complex production systems end-to-end and solo — from terminal-managed, security-hardened servers to polished, SEO-optimised interfaces.

Deep command of modern TypeScript stacks (Next.js, Fastify/tRPC, Node.js/Bun), high-performance infrastructure (OpenLiteSpeed, Nginx, Redis, Docker) and technical SEO. A designer-developer hybrid who has delivered web platforms, e-commerce, custom CRMs and automations for international clients — across language barriers, through precise, fully-written async collaboration.
