What I'm looking for

I am seeking backend or cloud-focused roles where I can build scalable Java microservices, work with AWS, and grow through challenging projects and collaborative teams.

I am a Java software developer with hands-on experience building Spring Boot RESTful APIs, microservices, and MySQL-backed applications, currently delivering production solutions at Tata Consultancy Services. I focus on clean, testable code—using JUnit and Mockito for unit testing—and on secure, well-documented APIs with Swagger and JWT-based authentication.

My project work includes backend systems for blogging and expense management where I implemented pagination, search, role-based APIs, and optimized CRUD operations; I also have practical AWS exposure and a strong foundation in data structures, operating systems, and databases. I collaborate with cross-functional teams to meet deadlines and provide prompt, sustainable fixes in production environments.
