About

Engineer by degree,
builder by obsession.

Outside of work, I love taking on personal projects that challenge me end to end. Shelfie is one of them, a full-stack social book tracking platform with real-time messaging and AI-powered features that I built from the ground up and deployed to production. For me there`s nothing quite like the feeling of turning an idea into something people can actually open in their browser.

At Everdays I worked across the full stack, shipping dashboards, client-facing features, a secure document upload system, and various backend improvements including new endpoints, schema refinements, and database restructuring to support a growing product.
