You will get a production-ready REST API in Node.js, Express and MongoDB
Project details
I build the backend of a learning platform serving 4,227 students in production right now - Node.js, Express, MongoDB, deployed and monitored. This project gets you the same standard: a clean, documented REST API, not a proof-of-concept that breaks under real traffic.
Four years of full-stack work, 20+ delivered projects. I write validated inputs, proper error handling, and endpoints you can actually hand to a frontend team the same day. Every tier includes source code, and I'm available for questions throughout - no waiting days for a reply.

HOW I WORK
I reply fast, ask questions before writing code, and ship working increments instead of one large drop at the end. I document as I build - my public repositories show exactly how I think about architecture, failure handling and trade-offs.
Tell me what you're building and I'll tell you honestly whether I'm the right person for it.
