What I'm looking for

I’m looking for a backend role where I can build secure, scalable microservices and APIs, improve performance and reliability, and raise code quality with strong testing—inside an Agile, security-first team that values long-term maintainability.

I’m a Backend Developer with 7+ years of experience across e-commerce, insurance, and airline loyalty domains. I’ve delivered secure, production-ready systems with performance tuning—moving from legacy code toward microservices while keeping reliability and maintainability as priorities.

Most recently, I led an incremental migration to Red Hat OpenShift, remediating security vulnerabilities ahead of monthly deployments and maintaining clean release sign-offs. I also improved legacy code quality by integrating JUnit/Mockito test suites (raising coverage from below 30% to 80%+), and built a microservices migration using the strangler pattern with Docker and CI/CD.
