About

I have hands-on experience in building secure and scalable backend systems using Java Spring Boot, along with full-stack exposure in React. I’ve worked on API design, JWT-based security, and performance optimization using tools like Redis, Kafka, and Docker. I can quickly contribute to production-ready solutions and adapt to modern development practices.
