What I'm looking for

I seek senior engineering roles where I can design scalable Java microservices, lead cloud-native deployments, mentor teams, and deliver secure, high-performance systems with strong CI/CD practices.

I am a senior software engineer with extensive experience building Java-based microservices, backend systems, and full-stack applications for banking, insurance, and web platforms.

I have architected core banking applications, optimized PostgreSQL performance by 20%, and led migrations from monoliths to microservices while ensuring test coverage with JUnit and Mockito.

I deploy and operate services on cloud and container platforms including AWS, Azure, OpenShift/Kubernetes, and automate CI/CD pipelines to improve delivery speed and reliability.

I mentor junior engineers, conduct code reviews, and collaborate across international teams to deliver secure, high-performance solutions integrated with enterprise systems like T24.
