Building reliable enterprise systems with Java, Spring Boot, and AWS — backed by 5+ years of experience.
Engineering Reliable Backends
Backend-focused Full Stack Java Developer with 5+ years of experience building enterprise applications using Java and Spring Boot. I design RESTful APIs, microservices, Kafka event flows, secure service layers, and JPA persistence.
On the cloud side, I ship containerized services to AWS (EKS, ECS, Lambda) through automated CI/CD pipelines, with strong experience in SQL tuning, NoSQL modeling, Redis caching, observability, and testing with JUnit and Mockito.
I also bring hands-on frontend experience with Angular, TypeScript, and RxJS, connecting workflow dashboards and reactive forms to backend APIs across Agile teams.
