Full Stack Developer

I build production-grade web applications across the full stack — scalable APIs, event-driven backends, and complex frontends, end to end.

About

Five years in, I still find the most interesting problems at the intersection of data and scale — designing APIs that don't fall apart under load, picking the right database for the job, and building systems that are easy to reason about six months later.

I work across the full stack without a strong preference for either end. Backends in NestJS, event-driven pipelines with Kafka, search with Elasticsearch, relational data with PostgreSQL and Prisma, frontend in Angular at work and React on personal projects. I pick whatever fits the problem.

I care about shipping things that actually work — not just passing tests, but holding up in production when something unexpected happens.
