What I'm looking for

I seek senior engineering roles focused on scalable backend/platform work, reliable operations, cloud migrations, and mentoring in security-conscious, collaborative teams.

I am a Senior Software Engineer with 10+ years building backend platforms and APIs for enterprise healthcare and HR operations, focused on reliability, data freshness, and operational quality. I have led modernizations, migrations to cloud platforms, and secure integrations while mentoring teams and establishing paved-road engineering standards.

My work includes accelerating large-scale ingestion workflows for 100k–400k+ users per run, implementing resilient microservice boundaries, improving incident response and observability, and driving Spring Boot migrations and Azure cutovers. I bring a pragmatic, security-conscious approach to delivery and a track record of measurable performance and stability improvements.
