Full Stack Engineer | React, NestJS, PostgreSQL, Healthcare SaaS & EHR
If you're building a healthcare SaaS platform, EHR system, or AI-powered web application, and you need someone who owns the full stack from React UI to NestJS API to AWS infrastructure, that's exactly what I do. I'm a senior full stack engineer with 8 years of production experience across healthcare, edX, fintech, and enterprise SaaS. My work spans complex React and NestJS systems, AWS CDK infrastructure, and AI integration, including clinical chat interfaces, agentic workflows, and LLM-powered features like automated care plan generation using Claude and Cursor-driven development. My most recent work is Star-EHR, a regulated, multi-tenant healthcare platform. I worked across the entire product: React frontend, NestJS backend, PostgreSQL database, AWS infrastructure, and integrations with QuickBooks, Microsoft Outlook, and BoldSign. 𝗪𝗛𝗔𝗧 𝗜 𝗕𝗨𝗜𝗟𝗗: ▪️React and Next.js frontends that are fast, clean, and built for real users ▪️NestJS backends with proper architecture ▪️PostgreSQL schemas designed to last, not just to work today ▪️AWS infrastructure as code using CDK - ECS, RDS, S3, CloudFront, SES, DynamoDB ▪️CI/CD pipelines with versioned releases, DB snapshots, and rollback procedures ▪️Third-party integrations that don't turn into maintenance nightmares 𝗪𝗛𝗘𝗥𝗘 𝗜 𝗚𝗢 𝗗𝗘𝗘𝗣𝗘𝗥 𝗧𝗛𝗔𝗡 𝗠𝗢𝗦𝗧: Healthcare platforms have requirements that generic full stack developers ignore. I've worked directly with: ▪️Multi-tenant architecture with strict data isolation between clients ▪️HIPAA-aware patterns across the full stack ▪️RBAC and session security built into the API layer ▪️Audit logging and compliance-friendly data patterns ▪️Legacy data migration pipelines with dry-run support before production cutover ▪️Timezone-correct scheduling and calendar logic, the kind of detail that breaks apps silently ▪️Nx monorepo with multi-package architecture, fully dockerized, with automated release pipelines ▪️Background job scheduling and cron setup using pg-boss 𝗛𝗢𝗪 𝗜 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗪𝗢𝗥𝗞: ▪️I write documentation. I set up proper developer workflows. ▪️I treat deployments as events that need preparation, not just pushing to main and hoping. ▪️I engage with the problem, not just the ticket. ▪️I work best on long-term product builds where ownership matters. 𝗧𝗘𝗖𝗛 𝗦𝗧𝗔𝗖𝗞: ▪️Frontend — React, Next.js, TypeScript, Tailwind CSS, React Native ▪️Backend — NestJS, Node.js, REST API, OpenAPI, JWT, OAuth ▪️Database — PostgreSQL, Drizzle ORM, Database Architecture ▪️Cloud — AWS CDK, ECS, RDS, S3, Docker, CI/CD ▪️Testing — Jest, React Testing Library, Playwright, Postman, Detox ▪️AI & Agentic — Claude API, OpenAI, agentic workflows, chat interfaces, care plan generation.
