01 / about

Clean architecture, reliable systems, shipped on schedule.

A results-driven engineer with 4+ years designing and delivering scalable, high-performance applications. I started in electronics & IoT, moved through React/Next.js product work, and now consolidate roles usually split across senior engineering, infrastructure, and technical project management — owning the platform from schema to deploy.

Strongest in Node.js, NestJS, GraphQL, MongoDB, PostgreSQL, and Redis, with hands-on AWS production ownership. I'm now expanding toward DevOps and data-driven systems — and I lead by raising the quality of everything around me.
