What I'm looking for

I want to build secure, high-availability Java/Spring Boot services with Kafka and AWS—owning REST APIs, improving reliability with testing, and growing in distributed systems.

I’m a Java Backend Developer with 3+ years of experience building scalable backend systems using Java, Spring Boot, Hibernate, and microservices. I design RESTful APIs, implement secure authentication with Spring Security and JWT, and integrate third-party services to strengthen real-world workflows.

At Increff Technologies, I built notification APIs integrating SMS, WhatsApp, and Email, and developed microservice components using clean architecture. I also test APIs using Postman and JUnit to improve reliability and reduce production issues.

My project work includes LifeLineX, a real-time emergency response system built with Spring Boot and Apache Kafka, using event-driven design, retry mechanisms, and Dead Letter Queues for fault tolerance. Previously, as an Android Developer Intern, I delivered a quiz module and Firebase-backed authentication/data storage, and I continue aiming to grow in backend and distributed systems.
