About

I’m a backend-focused, experienced Software Engineer building scalable, secure, and high-performance backend systems for production. My primary expertise is in Node.js, Java and Spring Boot, where I design RESTful APIs, implement JWT-based authentication and RBAC, and optimize databases for performance and reliability. I also have experience working with Node.js and Express for backend services, giving me flexibility across modern backend stacks. I’ve delivered cloud-native, containerized deployments on AWS (ECS) using Docker and CI/CD pipelines, enabling scalable infrastructure and zero-downtime releases. I’ve contributed to production-grade systems serving thousands of daily users, collaborating closely with product and frontend teams to turn business requirements into maintainable backend solutions. I’m passionate about backend engineering, system design, and performance optimization, and I enjoy building systems that scale.
