What I'm looking for

I'm seeking a backend role where I can build scalable systems using Java and Spring Boot. I value clean code, strong engineering culture, and opportunities to grow in areas like microservices, cloud infrastructure, and distributed systems. Open to remote or hybrid roles with teams focused on impactful products and continuous improvement.

I’m a Java backend developer with over 5 years of experience building robust, scalable, and high-performance enterprise systems. Throughout my career, I’ve focused on backend engineering using the Spring ecosystem (Spring Boot, Spring Data, Spring Cloud), working across industries like fintech, biometrics, and identity verification.

Outside of work, I enjoy learning about distributed systems and contributing to tech discussions on Medium. I’m also Oracle-certified (OCPJP SE 8) and continuously seeking opportunities to grow both technically and professionally.

I’m especially interested in backend roles where I can build high-impact systems, contribute to architectural decisions, and collaborate with driven teams solving real-world problems at scale.
