About this gig
Need a reliable backend for your web or mobile app? I build secure, well-documented REST APIs with Node.js and TypeScript.
What you get:
- Clean REST endpoints (Express or NestJS)
- PostgreSQL or MongoDB database design
- JWT authentication and role-based permissions
- Input validation and error handling
- Swagger/OpenAPI documentation
- Docker setup (Premium)
I have 3+ years building production backends for fintech, ERP and SaaS platforms: loan management, e-invoicing, payments and multi-tenant systems.
How we work:
- You tell me what your app needs
- I confirm the scope and timeline before starting
- You get progress updates and the full source code
Please message me before ordering so we can confirm the scope together.
