What I'm looking for

I seek backend roles focused on Spring Boot microservices, APIs, and scalable systems within collaborative Agile teams offering mentorship and growth opportunities.

I am a Java backend developer experienced in designing and implementing Spring Boot microservices for scalable, production-grade systems.

I've contributed to full SDLC across Agile teams, delivering clean, tested code, resolving production defects, and building APIs aligned with business goals.

My work emphasizes reliability and performance — using Resilience4J, asynchronous communication patterns, Hibernate/JPA, Kafka, and comprehensive testing with JUnit and Postman.

I mentor junior developers, participate in code reviews, and engage directly with stakeholders during sprint demos to ensure alignment and timely delivery.
