I’m a backend-focused Java Developer with 3+ years of experience designing and delivering enterprise applications. I build production-grade systems using Spring Boot, Hibernate, RESTful APIs, and SQL—delivering real operational value through solutions like a statistical quality control platform and a customer portal serving 50+ operational analysts daily.

In my current role, I optimize critical SQL queries with Spring Data JPA and Hibernate to improve API response times and system throughput. I also implement role-based access control with Spring Security to remove bottlenecks, develop incident management workflows that reduce mean time-to-resolution, and automate lab data aggregation and dynamic report generation—eliminating about 6 hours per week of manual analyst effort. I collaborate closely with QA and operations in Agile sprints through Jira, owning delivery from design to integration.
