I will develop a rest API in net 8 with c and entity framework
Vitor Nunes
About this gig
Looking for a developer who builds REST APIs you can actually deploy in production, not just demo on localhost? Read on.
I'm a Brazilian full stack dev focused on .NET 8 and Angular. My main project right now is connectveiculos.dev.br, a multi-tenant SaaS for vehicle dealerships that handles authentication, separate databases per tenant, and integrations with Mercado Livre and WhatsApp Business.
So I know what breaks when APIs hit real traffic - not just textbook scenarios.
Here is what comes in each package:
Basic - 3 CRUD endpoints, SQLite, source code on GitHub
Standard - 6 endpoints, JWT auth, Swagger docs, PostgreSQL or SQLite
Premium - 10+ endpoints, JWT with role-based access, Swagger, xUnit tests, Docker, deploy guide. Stack I work with: C#, .NET 8, ASP.NET Core, EF Core, SQLite, PostgreSQL, SQL Server, JWT, FluentValidation, xUnit, Docker.
Things I will not do:
- Frontend or mobile (Angular dashboard can be added as an extra)
- Skip tests on Premium just to deliver faster
- Reverse-engineer or scrape third-party systems
If you want to align expectations before ordering, send me a message describing your project. I reply within a few hours during business

FAQ
Will I receive the source code?
Yes, every order includes the full source code delivered via a private GitHub repository (or .zip), with a README explaining how to run it locally.
Can you work with my existing database?
Yes, I can connect to an existing SQL Server, PostgreSQL, MySQL, or SQLite database. Send me the connection string and schema before ordering so I can confirm compatibility.
What if I also need a frontend?
I can build an Angular admin dashboard as an extra (see the Angular dashboard extra). It includes login, CRUD pages for your endpoints, and Tailwind CSS styling.
Do you use AI to write the code?
I use tools like Copilot for productivity, but every API is architected, reviewed, and tested by me. No raw AI output gets shipped.
Can you deploy the API to a cloud server?
Yes, I offer cloud deployment (Docker, Nginx, HTTPS via Lets Encrypt) as an extra. I have already done this for my own ConnectVeiculos project on Oracle Cloud Always Free.
