Project details

Need a clean, documented, production-ready REST API, not spaghetti code that breaks in production?

I'm a full-stack developer with real production API experience. I built and deployed FIMS, a full-stack ERP system with 40+ REST APIs actively used by 3 real manufacturing units daily. Every endpoint is tested with Jest, documented with Postman, and secured with JWT authentication and Role-Based Access Control.

What you get with every API:

• Clean RESTful design with proper HTTP methods and status codes
• JWT authentication and role-based access control
• PostgreSQL database design with optimized indexing
• Input validation and proper error handling
• Full Postman collection documenting every endpoint
• 80%+ test coverage using Jest
• Docker-ready setup for easy deployment
• Clean, documented source code via GitHub

I've reduced query latency by 30% using B-Tree indexing in production. I don't just build APIs, I build APIs that scale.
Message me with your requirements and I'll tell you exactly how I can help.

About Smit

Full-Stack Engineer | Production SaaS & Real-Time Systems

Most developers hand you working code and disappear. I hand you a system that runs in production, doesn't break at 2am, and that you actually understand when it's delivered.

My flagship build is FIMS (Factory Inventory Management System), is actively used by 3 manufacturing facilities every day. It handles real-time inventory sync via SocketIO, 40+ REST APIs with JWT authentication, Docker-based deployments, and role-based access control. It's not a demo. It's running right now.

Here's what you get when you work with me:

→ Full-stack systems built with React 18, Node.js, Express, PostgreSQL

→ Real-time features using SocketIO (live dashboards, notifications, sync)

→ REST APIs with proper auth, error handling, and documentation

→ Docker deployments you can actually maintain

→ 80%+ test coverage so bugs get caught before your users do

→ CI/CD pipelines via GitHub Actions — push to deploy, no babysitting required

I have time, energy, and hunger that senior developers charging 5x my rate simply don't. I treat every project like it's going on my permanent record, because on Upwork, it is.

If you want clean code, honest timelines, and someone who communicates before problems happen, let's talk.
