When your backend goes down, users leave and revenue stops. I make sure that doesn't happen. I'm a Node.js backend developer with four years building and stabilizing production APIs and microservices across Healthcare, FinTech, EdTech, and Real-Time platforms — industries where uptime and data integrity aren't optional. Results I've delivered: — Migrated a live MongoDB database to PostgreSQL with zero downtime and zero data loss, across a 50+ user production system — then rebuilt the backend logic to handle PostgreSQL natively where it had only ever run on MongoDB — Migrated a MySQL database on a live PWA to Supabase PostgreSQL with Row Level Security and proper schema versioning — eliminating data corruption bugs that were wiping user progress, streaks, and financial records on every deploy — Expanded and restructured a PostgreSQL microservices database to support unified authentication across multiple services — users can now sign up, log in, and manage their profile from one platform with one login What I build for clients: API development — High-performance RESTful and GraphQL APIs using Node.js, Express.js, and NestJS, designed to handle load and stay maintainable as your product grows. This is the kind of API work a reliable Node.js backend developer should own end to end. Microservices architecture — Modular, independently deployable services built for scale, with clean inter-service communication and separation of concerns baked in from the start. Database architecture — MongoDB and PostgreSQL schemas structured for speed and long-term integrity, including advanced indexing and query optimization (one recent project cut DB load by 40%+). Real-time systems — WebSockets, live messaging, and presence features built cleanly into your existing stack. Auth & security — JWT, RBAC, OTP flows, and session management done properly from day one. Infrastructure & deployment — Docker, CI/CD pipelines, and automated monitoring so you're never caught off guard. Third-party integrations — Payment gateways, Twilio, and external APIs connected without future maintenance debt. 🧩 Real-World Solutions I've Built as a Node.js Backend Developer: 🏥 Healthcare Data Pipeline Built a Node.js backend processing 1,000+ patient records daily across a distributed system — with zero data loss, role-based access control, and HIPAA-aligned data handling built in from day one. 🏫 Multi-School Platform Backend Architected a modular Node.js microservices backend for EduConnect, serving 10+ schools with complex role hierarchies, tenant isolation, and data scaling — all without touching live service uptime. 🆘 Real-Time Crisis Support API Built the backend for Safe Anchor — a real-time victim support platform using Node.js, WebSockets, and optimized REST APIs, with encrypted communications and secure data handling under strict compliance requirements. ⚡ API Performance Overhaul Diagnosed and resolved bottlenecks across a production API layer — cutting response times by 45% through query restructuring, caching strategy, and connection pool tuning on PostgreSQL. 🗄️ Database Migration & Stability Migrated a live MySQL database on an active PWA to Supabase PostgreSQL — eliminating data corruption bugs wiping user progress and financial records on every deploy, with Row Level Security and schema versioning built in. ☁️ Zero-Downtime MongoDB to PostgreSQL Migration Migrated a live MongoDB database to PostgreSQL across a 50+ user production system with zero downtime and zero data loss — then rebuilt the backend logic to handle PostgreSQL natively from the ground up. If you need a backend that handles load, protects your data, and gives your product a solid foundation that lasts — let's talk to a Node.js backend developer who has done it in production.

One of my clients just closed $1M in seed funding on a SaaS platform I built. Another is running a live AI agent inside medical practices, fully HIPAA compliant. I am a Full Stack AI Engineer with 8 years of experience and 20+ AI and SaaS products shipped. If that is what you need, keep reading. Most AI projects fail between the demo and production. The agent works in a sandbox, the RAG pipeline pulls wrong context in the real environment, and the SaaS MVP that looked perfect in staging cannot handle actual users. That gap is what I close. IBM and Meta certified |Top Rated. FinTech, MedTech, and EdTech. Here is what I build and what it actually does for your business: AI Agents and Multi-Agent Systems using LangGraph, LangChain, and CrewAI that execute real business workflows so your team stops doing manually what a system should handle automatically. 2. RAG systems that stop your AI from giving wrong answers to paying customers. Hybrid retrieval, re-ranking, and evaluation pipelines built on Pinecone, pgvector, and ChromaDB. 3. SaaS MVPs and multi-tenant SaaS platforms with auth, Stripe billing, role-based access, and admin dashboards that go live in weeks, not quarters. 4. AI workflow automation connecting n8n, Make, and Zapier to LLM backends that permanently replace manual processes across your operations 5. Production deployments on AWS, GCP, and Supabase with Docker, CI/CD, and observability built in from day one, not patched in after something breaks. Two products I shipped recently: Dandalee is a procurement SaaS platform for the Architecture, Engineering, and Construction industry. Built end-to-end on Next.js, Express.js, and n8n automation. It onboarded 2,000+ sellers, closed a $50K bridge round, and secured $1M in seed funding in Q1. Doclatch is a HIPAA-compliant AI healthcare assistant built on LangChain and FastAPI. It parses unstructured medical documents, extracts clinical context, and generates structured staff task cards with source-level citations so every AI output is liability-proof for the practice.
