About

A bit about me

I’m a backend-focused software engineer with 6+ years building scalable, secure systems in Java and Spring Boot. I’ve architected microservices for high-stakes domains — healthcare integrations, global promotional pricing, identity & access management, and next-generation emergency alerts.

I enjoy owning architecture end-to-end: translating ambiguous, cross-functional requirements into clean domain models and APIs, then driving them through to delivery. I care about performance, reliability, and compliance — whether that’s meeting 100% of HIPAA requirements or cutting API latency by 90%.

Along the way I’ve led backend workstreams, mentored junior engineers, and been recognized with several awards for technical leadership and delivery.
