What I'm looking for

I’m looking for a mission-driven team where I can lead end-to-end AI/ML and agentic product delivery—building reliable RAG/LLM systems, scaling microservices on cloud, and improving quality and security with measurable impact.

I’m a Strategic and innovation-driven Software Engineering Lead with 5.5+ years of experience, specializing in AI/ML engineering, GenAI, and Agentic solutions—especially in healthcare. I’m motivated by turning complex model and data capabilities into real products that improve health outcomes and operational efficiency.

At UnitedHealth Group, I’ve led enterprise-scale delivery by coordinating teams of 15+ engineers through CI/CD pipelines (GitHub Actions toward AWS managed services) to ensure 100% on-time release with zero major compliance violations. I also directed an agentic automation pipeline with CrewAI and integrated Document AI, OCR, and vector databases—cutting processing time by 40% over a 9-month development cycle.

Previously as a Senior Software Engineer, I spearheaded migration of deployment pipelines from Jenkins to GitHub Actions, and helped evolve decision systems by moving from RedHat Rules Engine to DROOLS. I designed and shipped a GraphQL microservice for AI/ML data access, while strengthening security posture through remediation of critical vulnerabilities across microservices.

Earlier, as a Founding Engineer at Cratoflow, I built core platform capabilities—from customer onboarding microservices (99.98% uptime) to a rules engine and portals—using Docker, Kubernetes, ReactJS, and Spring Boot. I value scalable architecture, measurable outcomes, and secure interoperability as the foundation for trustworthy AI/ML.
