FAQ
Can you work on my existing codebase?
Yes. I can extend, fix or refactor an existing Node.js, NestJS or Express backend. Share the details and I'll review it first.
Will I get the full source code?
Yes. Every package includes the complete source code and setup instructions, delivered through Fiverr or a private GitHub repo.
Which package should I choose?
Basic is for small APIs of up to 5 endpoints, Standard adds authentication and documentation, and Premium is a full production backend with deployment. Message me if you're unsure and I'll recommend one.
Can you deploy the backend for me?
Yes. Deployment on AWS with Docker is included in Premium and can be added to other packages on request.
