Ten years architecting production-grade web applications across sports tech, e-commerce, SaaS, and B2B commerce. Backend depth in NestJS and Node.js, paired with React on the frontend.

Building the web,
one project at a time.

Senior full stack developer with 10+ years designing, building, and scaling production-grade web applications. Deep expertise in backend development with NestJS and Node.js, paired with React.js for responsive, user-centric frontends.

I have a proven track record of architecting REST APIs, microservices, and distributed systems for high-traffic platforms across sports technology, e-commerce, SaaS, and B2B commerce. My day-to-day spans TypeScript, database design across PostgreSQL and MongoDB, containerisation with Docker and Kubernetes, and CI/CD automation.

I lead cross-functional engineering teams while maintaining individual technical excellence, focused on clean, maintainable code, secure-by-default authentication patterns (JWT, OAuth), and adopting AI-assisted development tools to push productivity and quality forward.
