What I'm looking for

I'm looking to build scalable backend and distributed systems where I can improve performance, reliability, security, and developer delivery through Java, Go, cloud infrastructure, and DevSecOps.

At Mphasis for Charles Schwab, I architect and scale trading execution APIs, improving throughput by 20%, reducing recurring production bugs by 35%, and strengthening transaction security for SOC-2 compliance.

I've also built e-commerce microservices and zero-downtime AWS delivery pipelines for FavShoes, while creating Friday, a Go-based in-memory event broker and hybrid vector search engine with sub-2ms routing and search. I bring hands-on experience with Java, Go, Spring Boot, distributed systems, databases, observability, and DevSecOps.
