What I'm looking for

I’m looking to build secure, high-availability fintech systems end-to-end—API-first microservices, responsive frontends, and cloud-native CI/CD—where teams value reliability, compliance, and strong architecture across the full SDLC.

I’m a full stack software engineer with 6+ years of experience designing, developing, and maintaining scalable fintech and enterprise applications across the full SDLC. I’m especially strong in Java (Spring Boot, Spring Cloud), microservices-based architectures, RESTful API design, and ORM frameworks (Hibernate, JPA), with a track record of translating complex business and regulatory requirements into robust lending, mortgage, and portfolio solutions.

Across production systems, I’ve built high-availability financial workflows supporting 500K+ daily active users, improved processing speed by 30%, and delivered frontend experiences with React and Angular that reduced average page load time by 40%. I bring cloud-native development and operational excellence—AWS/Azure, Docker/Kubernetes, CI/CD automation (Jenkins and GitHub Actions), and careful secure coding—so teams can move fast while maintaining reliability, stability, and compliance.
