What I'm looking for

I’m looking to build fast, reliable, and maintainable backend systems and secure APIs. I want to work with modular architecture, strong authentication/authorization, and CI/CD on AWS with Docker—ideally open to remote.

I’m a Backend Engineer with 3+ years designing and deploying production-grade REST APIs using TypeScript and Node.js. I focus on clean modular architecture and strong API security—JWT auth with refresh token rotation, authorization flows, and logout invalidation mechanisms.

I’ve built backend services for a location-based transportation management platform, including user management, trip workflows, driver–rider interactions, and transaction processing. I also design relational database models (MySQL/PostgreSQL), optimize performance through indexing and query optimization, and ship reliable deployments on AWS with Docker and CI/CD via GitHub Actions.
