I will integrate fedex ups usps shipping api and automate order fulfillment
Mohsin Javed
À propos de ce service
Your store or ops team is manually creating shipping labels, copy-pasting tracking numbers, or paying for a bloated all-in-one shipping platform you don't need. I build direct, production-grade integrations with FedEx, UPS, USPS, and DHL APIs - rate calculation, label generation, and tracking - wired straight into your existing app or a new one I build for you.
This isn't a quick REST call bolted onto a form. I recently built a production fulfillment platform for a multi-vendor operation: FedEx API integration generating and caching shipping labels as PDFs, a background job queue so bulk label generation for hundreds of orders doesn't block the app, and a full order/batch management system on top. That's the standard I build to - see my portfolio for the real thing.
What you get: real carrier rate shopping, PDF (or ZPL for thermal printers) label generation, tracking capture and status updates, and - if you need it - the background processing to handle real order volume without timing out. Built on Node.js/TypeScript; other stacks on request.
Message me with your carrier(s), current stack, and order volume - I'll tell you honestly if Basic covers it or you need more.

I'm Mohsin, a Software Engineer specializing in React, Next.js, Node.js, Express, TypeScript, PostgreSQL, and Docker. My work centers on two things: building and integrating shipping/carrier APIs (FedEx, UPS, USPS) for rate calculation, label generation, and order tracking — and building custom POS and inventory systems, like xPOS, an offline-first system with real-time multi-register sync, reporting, and AI-driven insights. I also build REST APIs, design databases, fix bugs, and maintain existing applications with clean, reliable code.

FAQ
Which carriers do you support?
I currently integrate FedEx, UPS, and USPS APIs — rate calculation, label generation, and tracking. If you need a different carrier, message me first so I can confirm their API supports what you need before you order.
Do I need my own carrier API account?
Yes — you'll need active developer/API credentials from your carrier (FedEx, UPS, or USPS). I don't provide carrier accounts myself, but I can walk you through registration if you're not sure where to start.
Can this integrate with my existing backend or order system?
Yes. My primary stack is Node.js/Express, so I can plug directly into a Node backend. For other stacks, I connect through your existing REST API or database — share your setup when we start and I'll confirm the approach before beginning work.
Do you support thermal-printer (ZPL) labels, or only PDF?
All packages include standard PDF labels. ZPL/thermal-printer output can be added if you need it — just mention it in your requirements when you order so I scope it correctly from the start.
Which package should I choose for my order volume?
Basic suits a single carrier and low order volume. Standard fits stores using 2+ carriers with rate shopping and tracking. Premium is for higher-volume sellers who need bulk labels and batch background processing. Tell me your approximate daily order count and I'll confirm the right fit.
