What I'm looking for

I’m seeking a senior engineering role building production-grade AI and cloud-native backend systems with strong engineering practices, mentorship opportunities, and a collaborative, security-conscious product culture.

I am a Senior Software Engineer with 11+ years building cloud-native, high-availability systems across Healthcare IT, Digital Health, E‑Commerce, and B2B SaaS. I design and scale backend services, lead architecture decisions, and mentor engineers to deliver reliable production software.

I have strong hands-on expertise in Python and FastAPI, building AI-powered systems using RAG, AI agents, embeddings, and vector search. I’ve integrated enterprise-grade foundation models via AWS Bedrock and Google ADK, and implemented production ML workflows with observability, compliance, and cost optimization in mind.

I deliver measurable business impact by partnering with product, security, and platform teams, instituting CI/CD, automated testing, and secure, HIPAA-compliant designs. I enjoy mentoring teams, driving best practices, and shipping scalable, performant systems.
