About

I’m a currently SDE 1 with hands-on experience in building scalable, high-performance applications using Java, Spring Boot, REST APIs, and SQL/NoSQL databases. I enjoy solving complex problems, optimizing backend systems, and working across distributed microservices. I’ve worked on API development, query optimization, migration of legacy systems, debugging production issues, and improving end-to-end performance. I value clean code, teamwork, and continuous learning.
