What I'm looking for

I seek hands-on roles where I can own product technical direction, ship end-to-end systems, and mentor teams in fast-moving, impact-driven environments.

I am a hands-on lead product engineer with startup experience building and scaling production systems from 0→1, focused on ownership, speed, and user impact. I have led transitions from MVP to production IoT platforms, built engineering foundations (CI/CD, infrastructure, monitoring), and driven technical direction while remaining deeply involved in implementation.

My background spans backend, cloud, and frontend — shipping high-throughput logistics features, designing GraphQL schemas, modernizing legacy systems, and implementing robust architectures with Node.js, TypeScript, NestJS, AWS, Docker, and databases like MongoDB and PostgreSQL. I deliver pragmatic architecture, fast execution, and cross-functional leadership to enable reliable, user-focused products.
