What I'm looking for

I’m looking for a role where I build secure, test-driven Java/Spring services and responsive web experiences, working with CI/CD and cloud deployments, and growing with a collaborative engineering team.

I’m a Software Development Engineer who builds secure, reliable systems using Java, Spring, and modern web technologies. In my current role, I implemented authentication and authorization with JWT and Spring Security, reducing unauthorized access incidents by 90% while strengthening application security.

I also automate backend workflows and validation processes, cutting repetitive manual tasks by 50% to improve operational efficiency. I focus on quality through unit and integration testing with JUnit and Postman, achieving 85% test coverage and significantly reducing production bugs.

Previously, as a Full-Stack Developer Intern, I developed responsive applications using React.js, HTML, CSS, and JavaScript—boosting user engagement by 50% and reducing runtime errors by 30%. I’m comfortable designing RESTful APIs with Java and Spring Boot, optimizing performance (35% faster response times), and modeling relational databases in MySQL with strong DBMS and SDLC fundamentals.
