You will get a secure, fully documented REST API backend using .NET or NestJS
Project details
Stop struggling with spaghetti code and undocumented endpoints. Get a backend that is built to scale and easy to consume.
As a developer with a strong Frontend background, I know the pain of integrating with messy APIs. That is why I build Backends differently: I prioritize clear structure, strict typing, and perfect documentation (Swagger) so your frontend team can work without frustration.
In this project, I will build:
RESTful API Architecture: Clean, modular code using .NET Core or NestJS.
Database Integration: Optimized schemas for PostgreSQL or SQL Server using EF Core or TypeORM.
Security: Implementation of JWT Authentication, Password Hashing, and Input Validation.
Documentation: Fully auto-generated Swagger/OpenAPI docs so you know exactly how to test every endpoint.
Why choose me? I don't just write code that "works"; I write code that is maintainable. I use industry-standard patterns (Repository Pattern, Dependency Injection) to ensure your backend is future-proof.
Choose a tier and let's build a solid foundation for your app!

Front End Developer Web3 – UI/UX, Angular & TypeScript (NestJS, REST API)
About David
Senior Full-Stack Developer | C# & TypeScript
Champigny-sur-Marne, France - 2:15 pm local time
Building scalable, enterprise-grade web applications with clean architecture from UI to database.
I design and deliver complete systems: modern Angular frontends paired with reliable, well-documented backends. My core advantage is depth on both sides of the stack. I understand how frontend state, performance, and UX depend on API design—and I build both accordingly.
If you need someone to take ownership of a product end-to-end (or stabilize a critical part of it), I’m a strong fit.
