Senior Full -Stack Engineer at Lumenwell Health

Led decomposition of a legacy Express monolith into 6 domain microservices on Node.js/Docker/ECS, cutting average deploy time from 40 to 6 minutes and reducing production incidents by 45% quarter-over-quarter. Designed and shipped an AI-assisted clinical note summarization feature using Anthropic with an RAG pipeline (LangChain + pgvector), adopted by 78% of active clinicians within two months and reducing documentation time by ~6 minutes per visit. Rebuilt the patient-facing dashboard in Next.js/TypeScript with server components and React Query, improving Core Web Vitals (LCP 4.1s to 1.6s) and reducing load-failure related support tickets by 60%. Introduced Redis-backed caching and query-plan review for MongoDB/PostgreSQL, reducing API p95 latency from 810ms to 220ms on top endpoints. Built real-time appointment/messaging notifications using Socket.IO and SQS, scaling to 12k concurrent connections without added infrastructure cost. Set up GitHub Actions CI/CD with automated Cypress/Je
