Need a backend that doesn't break when traffic arrives?

FAQ
I only have a frontend. Can you build the backend to match?
Yes, that's one of my most common projects. Send me your frontend (even screenshots work) and I'll map out the API contract
Can you work with my existing codebase?
Yes, if it's Node.js-based. I can refactor, extend, or fix what's already there. Please share the repo before ordering.
Do you write tests?
Basic unit/integration tests are included in the Premium package. For full test coverage, we can scope it as a separate order.
What happens after delivery if something breaks?
Standard and Premium include revisions. Premium includes 7 days of post-launch bug fixes on my code at no extra cost.
