<>About Me</>

Engineer. Tech Lead. Architect.

<>I am a full-stack JavaScript engineer with over 15 years' experience in building web applications across the USA, Europe and Latin America. I started out with .NET and corporate systems before evolving towards modern JavaScript, including React, Node.js and TypeScript. Having worked as an individual contributor, tech lead and architect, I can write code, review architecture or both. My focus is not on the stack, but on creating working software that solves real problems for real users.</>
