About Me

👨‍💻

I'm a Full Stack Software Engineer who builds enterprise applications across the stack — REST APIs, backend microservices, frontend UIs, and cloud deployments on AWS.

Today I lead the annuities team at BDIPLUS on a modernization program for a US-based life insurance client. I own delivery end to end: client calls and requirements, architecture, a team of 5 developers, and AWS deployment — modernizing IBM IIB and webMethods integrations into Java 21 Spring Boot microservices, with 80%+ of the annuities scope delivered.

I'm strongest in REST API design, secure authentication (JWT), observability, automated testing, and CI/CD. When I'm not coding, I'm solving problems on LeetCode.

When I'm not coding, I'm solving problems on LeetCode and continuously leveling up my skills.
