What I'm looking for

I seek senior engineering roles building AI-driven, cloud-native systems in collaborative, outcome-focused teams where I can lead technical design, mentor engineers, and deliver measurable impact.

I am a Senior Software Engineer with 10+ years building full-stack, AI-enabled, cloud-native systems across healthcare, SaaS, and enterprise platforms. I specialize in microservices, event-driven architectures, and DevOps automation on AWS, GCP, and Kubernetes, and have delivered measurable improvements like 40% faster patient intake, 99.9% uptime, and 30% faster delivery cycles.

I lead cross-functional teams to integrate AI (OpenAI RAG, embeddings), EHR interoperability (FHIR, Epic, Cerner), real-time communications (Twilio, WebRTC), and scalable APIs using Spring Boot, FastAPI, React/TypeScript, Kafka, and Redis. I prioritize secure, HIPAA-compliant solutions, test-driven development, and observability to retire legacy systems, cut costs, and accelerate delivery while mentoring engineers and improving team velocity.
