What I'm looking for

I'm looking to build scalable, reliable distributed systems where I can drive microservices architecture, cloud deployment, healthcare interoperability, real-time data workflows, and AI-powered automation.

I've built healthcare interoperability platforms at Mediphore Systems and Technologies, including HL7, CCDA, and DICOM ingestion pipelines for Epic, Cerner, and Allscripts. My work improved data integration efficiency by 35%, enabled real-time imaging access, and applied Agentic AI to reduce manual clinical document processing by 40%.

At RootQuotient Technologies, I developed FastAPI and Java/Spring Boot microservices for more than 10,000 concurrent users, optimized SQL and Redis caching to reduce latency by 40%, and deployed containerized services across AWS and GCP. I also delivered secure OAuth 2/OpenID integrations, Stripe payments, KYC workflows, and full-stack React applications.

I've led code reviews, mentored junior developers, and built reliable systems across healthcare, sustainability, genomics, and cancer registry products using Node.js, Python, Java, TypeScript, Docker, Kubernetes, and cloud CI/CD tooling.
