I’m a Java Full Stack Developer with 4+ years of experience delivering distributed applications, microservices, REST APIs, and data-processing workflows across insurance, healthcare, and aerospace environments. I’m production-focused: I improve reliability through automated testing, code reviews, CI/CD, and disciplined troubleshooting.

In my recent work, I developed Java and Spring Boot microservices for modular REST endpoints and configurable business components. I implemented Kafka producers and consumers with retry handling and failure logging, so asynchronous transaction processing doesn’t block customer-facing requests.

I also focus heavily on performance and data access. I improved response times by ~22% using Redis caching, GraphQL batching, and revisions to Cassandra/SQL access patterns, and I refactored persistence logic with Spring Data JPA and Hibernate to clarify transaction boundaries and reuse repository operations.

Beyond core services, I strengthen systems end-to-end—security, deployment, and observability. I’ve applied Spring Security with OAuth/TLS/SAML controls, built Spring Batch jobs for restartable workloads, supported Docker-based AWS deployments, and investigated incidents using Splunk and CloudWatch while maintaining repeatable test suites with JUnit, Mockito, Postman, and Selenium.
