What I'm looking for

I seek senior engineering roles building AI-enabled, cloud-native systems with strong DevOps culture, cross-functional collaboration, and opportunities to mentor and drive technical strategy.

I am a Senior Software Engineer with 10+ years building full‑stack, cloud‑native, and AI-driven solutions across healthcare, SaaS, and enterprise platforms. I focus on microservices, event‑driven systems, and DevOps automation to deliver reliable, high‑performing products.

I have led large integrations including HIPAA‑compliant Health Cloud rollouts, EHR interoperability (FHIR, Epic, Cerner), and OpenAI‑powered RAG pipelines that improved intake speed by 40% and reduced call handling time by 30%. I architect scalable systems on AWS, GCP, and Kubernetes while maintaining 99.9% uptime through CI/CD and resilient deployment strategies.

I enjoy mentoring engineers, driving cross‑functional initiatives, and applying AI/ML to practical problems. I strive to accelerate delivery cycles, cut operational costs, and build production‑grade services with strong test coverage and observability.
