About
I’m a senior full-stack engineer with seven years of experience building scalable backend services in Node.js and PostgreSQL, and delivering reliable features across mobile and web. I enjoy owning the full development lifecycle—from database schema design and performance tuning to API development and polished client experiences—while keeping an emphasis on stability, observability, and maintainable engineering practices.
In recent roles, I’ve led mobile app redesigns with React Native and Expo, created and optimized PostgreSQL architectures for high-volume metadata and user relationships, and built backend services for authentication, content ingestion, and real-time notifications. I also help raise team quality by introducing strong automated testing standards (Jest and Detox), and I’ve integrated third-party APIs for enrichment, analytics, and logistics to ensure dependable end-to-end functionality for global users.
