I will build production ready rest API integrations for saas, and payment systems
About this gig
THE PROBLEM MOST API DEVELOPERS WON'T TELL YOU:
Most freelancers will build what you describe. They'll deliver code that works on their machine, in their test environment, with perfect conditions.
Then you deploy it. And it breaks.
Not because they were bad people because they built a prototype, not a production system. No error handling for edge cases. No rate limit management. No logging. No versioning strategy. No documentation your next developer can actually use.
You're not just buying code. You're buying a system that has to run when your customers are depending on it.
WHAT I BUILD AND HOW I BUILD IT:
I design and develop API integrations that are built for the real world: high-traffic conditions, unexpected inputs, third-party downtime, and the developer who comes after me.
Every delivery includes:
- Full Postman collection for endpoint testing
- API documentation (readable by humans and developers)
- Error handling and response standardization
- Deployment-ready codebase with inline comments
- Handoff call or async video walkthrough
I work with founders, CTOs, and product operators who have real timelines, real users, and real revenue on the line. If that's you let's talk.

FAQ
I'm not technical. Can you help me figure out what I actually need before I buy?
Absolutely, and this is exactly where we should start. Send me a message describing what your tools are, what you want them to do, and where the current breakdown is. I'll translate that into a clear technical scope and tell you which package fits.
How is this different from hiring any other API developer on Fiverr?
Most developers build to spec: You describe it, they build it, they deliver it. I build to outcome. I make sure what you've described will actually solve the underlying problem. I've seen too many clients get "working code" that didn't solve their real bottleneck. That's the gap I close.
Will I actually own the code you deliver?
Yes — full ownership, full source code, no licensing strings attached.
Can you work with my existing codebase or do you need to build from scratch?
Both. I regularly integrate new API layers into existing systems. Share your stack and I'll assess compatibility before the project starts. I won't take a project and discover a blocker two days in.
How do you handle scope changes mid-project?
If your requirements shift after we've agreed on scope, I'll give you a transparent assessment of the impact on timeline and cost before continuing. No surprise invoices. If the change is minor, I often absorb it. If it's substantial, we agree before I build.
What tech stacks do you work in?
Node.js, Python (FastAPI and Django REST Framework), PHP/Laravel on the backend. For automation layers: Zapier, Make, n8n with custom middleware. For databases: PostgreSQL, MySQL, MongoDB. If you're using something else, message me bcz the list of stacks I've touched is long.
What if I'm not satisfied with the final delivery?
I don't close a project until you're genuinely satisfied with what was built. I don't outsource, I don't hand off mid-project, and I don't disappear after delivery. The support window exists precisely because real-world deployment sometimes surfaces things a test environment doesn't.
