What I'm looking for

I’m looking for a Java backend role where I can build microservices and REST APIs, own production support, and drive performance improvements using CI/CD. I want an Agile team that values reliability, secure coding, and scalable architecture.

I’m a Java Backend Developer with 5+ years of experience building scalable enterprise applications in banking and telecom. I focus on delivering reliable backend services through clean microservices design, REST APIs, and production-ready implementations.

In my recent role, I built customer-facing onboarding REST APIs with Java, Spring Boot, and Microservices for YES BANK, while handling critical production bugs through root-cause analysis and targeted debugging. I’ve also supported zero-SLA-breach stability by shipping hotfixes via Jenkins CI/CD pipelines and improving performance through query profiling and indexing.

I care about long-term maintainability and quality: I’ve refactored legacy systems to improve runtime efficiency, authored JUnit and Mockito test suites, and migrated document storage to AWS S3 using secure bucket policies. I thrive in Agile/Scrum environments and collaborate closely with cross-functional teams to meet delivery deadlines.
