Secure .NET API Development with JWT & AILucas Aguilera
I build robust REST APIs and backend systems using C# and ASP.NET Core, from simple CRUD APIs to full solutions with JWT authentication and database integration (SQL Server, Entity Framework Core).
I also specialize in AI chatbot integration connected directly to your database using function calling (Google Gemini). Instead of generic AI responses, your chatbot answers real, specific questions about your own data.
What's included:
1 ASP.NET Core API module or small feature set
Up to 3 endpoints
JWT authentication setup for 1 user role
Basic Entity Framework data access
1 external AI API integration, if included
API documentation (Swagger)
Source code and setup notes
Not included:
Full application architecture
Frontend work
Payment systems
Deployment and cloud infrastructure
Complex role and permission systems
Large database design or migrations
Multi-agent AI workflows, dashboards, or ongoing AI tuning
Starting at $150 for the scope above (up to 3 endpoints, 1 user role, 5-day delivery). Larger projects or expanded AI features are quoted separately based on scope.
