I will be your backend developer for node js apis and typescript


About this gig
Your app needs a backend that does the job - and code your next developer can understand.
I will build a focused Node.js and TypeScript backend module for your product, with a clear API contract, input validation, useful error handling, and proof that the agreed workflow works.
I build Web2Labs, my own creator software, including its APIs, database workflows, and billing integrations. You work directly with the developer.
Choose your next step:
BASIC: a written implementation plan for one workflow. No code included.
STANDARD: one agreed API endpoint in a runnable project.
PREMIUM: one bounded backend module, up to 3 related endpoints.
Implementation includes source code, relevant tests, a test-environment walkthrough, and setup notes. We agree on the inputs, outputs, and acceptance checks before work starts.
Best for founders who have a clear next step and want it built carefully. Send me your stack, current setup, and the one workflow you need. I will confirm the right scope before you order.

FAQ
What does the Basic package deliver?
A written implementation plan for one workflow: API inputs/outputs, data needs, risks and acceptance checks. It does not include code. It is useful when the idea is clear but the build scope is not.
Is this a complete SaaS or app build?
No. This gig delivers one new backend module. A frontend, full authentication system, billing setup, multiple services or a complete SaaS is a larger project and needs its own agreed scope.
Which stack do you work with?
Node.js and TypeScript are the focus. My own product uses Express, Fastify, MySQL and TypeORM. Send your actual repository and versions first; I will confirm compatibility instead of assuming every framework is interchangeable.
What do you need before starting?
A runnable repository, setup steps and a safe test environment. Share redacted examples first. Do not paste passwords, production tokens or customer data into requirements; we will agree authorised, limited access.
How will I know the backend works?
We define acceptance checks before coding. Implementation delivery includes the source, relevant tests and a test-environment walkthrough showing the agreed requests, responses and failure handling.
Can you deploy it for me?
Source changes, test evidence and setup notes are included in implementation packages. Hosting and paid services are not. Deployment to an existing environment can be quoted after review; production changes require your approval.
What does one revision cover?
One consolidated revision covers changes within the agreed scope. A new feature, provider or workflow needs a separate quote. If my delivery misses an agreed acceptance check, I will correct that as part of the order.
Do you use AI-assisted tools?
I may use AI-assisted coding and analysis tools. I review the changes and test the agreed workflow. Tell me any code, data or tool restrictions before sharing files; we will agree the working method first.
