What I'm looking for

I’m looking to build scalable, event-driven fintech products, owning Java Spring Boot microservices, integrations, and CI/CD. I want a team focused on reliability, architecture, and measurable performance improvements.

I’m a Full Stack Developer with 3+ years of experience specializing in Java Spring Boot microservices, system integrations, and backend development for financial systems. I’ve built scalable banking applications, implemented complex business workflows, and integrated core banking systems like Flexcube and Pinelabs.

In my recent work, I develop event-driven payment and middleware services using Kafka and message queues, build REST/SOAP integrations, and design modules for ACH clearing, SWIFT messaging, and tax payment systems. I also strengthen reliability through CI/CD pipelines, Docker/AWS deployments, and production debugging, improving email delivery success by 30% and reducing API response time by 40%.
