I build and own production web applications that businesses depend on — currently leading a live insurance project at Tata AIG, running on AWS. Full-stack developer with nearly 5 years of experience in Node.js, NestJS, Angular and React, plus 2,300+ hours delivered on Upwork with a 5.0 rating. WHAT I BRING - End-to-end ownership: requirements, architecture, development, AWS deployment and production support — not just tickets - Enterprise and insurance-domain experience in regulated, customer-facing systems - AWS cloud expertise: scalable, secure deployments with CI/CD, monitoring and cost-aware infrastructure - Founder of Business Tracker, my own KPI and organisation-management SaaS — so I think like a product owner, not just a coder HOW I CAN HELP 1. Full-stack web apps & SaaS — NestJS/Node.js backends with Angular or React frontends 2. AWS cloud — architecture, deployment, CI/CD pipelines, migrations and cost optimisation 3. APIs & microservices — REST, gRPC, Kafka, RabbitMQ, API gateways (Apigee, Kong) 4. Legacy modernisation — AngularJS to modern Angular, monoliths to services 5. AI features — integrating LLMs (OpenAI, Claude) into real products 6. Rescue work — debugging, performance issues and production incidents STACK Node.js · NestJS · Express · TypeScript · Angular · AngularJS · React · PostgreSQL · MongoDB · MySQL · Redis · Kafka · Docker · AWS · Azure · GCP HOW I WORK - Clear written updates and a working demo early, not just at the end - Clean, documented, maintainable code you own fully - Based in Mumbai (IST) with overlap for UK/EU working hours and US mornings Have an app that needs to be built, scaled, moved to AWS or rescued? Send me the requirement or your repo, and I'll reply with a clear plan and estimate.
