I will build or fix a nodejs rest API with typescript
Oliver Drewing
About this gig
Are you looking for help with a NodeJS/TypeScript backend or REST API? I can help you build, fix or improve clean, maintainable backend code for your app, SaaS prototype or internal tool.
I work with NodeJS, TypeScript, Express.js, REST APIs, databases and API integrations. Depending on the package, I can fix one backend issue, build new API endpoints, connect your API to a database, improve error handling, validate request data or structure a small backend module.
Typical tasks:
- Fix backend bugs
- Create REST API endpoints
- Add database integration
- Improve TypeScript code structure
- Connect an app or frontend to an API
- Review and clean up existing backend logic
Please contact me before ordering if your project includes authentication, payments, complex business logic, external APIs or an existing codebase. This helps me understand the scope and avoid unrealistic delivery times.
You will receive clean source code, practical communication and a solution focused on maintainability, not unnecessary complexity.

I care about clear communication, practical decisions and production-ready software without unnecessary complexity.
FAQ
Can you work with an existing codebase?
Yes. Please send a short description of the issue or feature and, if possible, relevant code details before ordering. I will review the scope and tell you what is realistic.
Do you build complete SaaS platforms?
This Gig is focused on backend tasks, REST API endpoints, bug fixes and small backend modules. Larger SaaS projects need to be discussed first and may require a custom offer.
Can you add database integration?
Yes. Database integration is included in the Standard and Premium packages. For the Basic package, it can be added as an extra if the scope is small enough.
Can you connect my frontend or mobile app to an API?
Yes. I can help connect an app or frontend to a REST API, adjust endpoints, fix response handling or improve the backend structure needed for the integration.
What do you need before starting?
I need a clear description of the task, existing API routes if available, expected behavior, error messages, database details if relevant and access to the code or repository when needed.
