I will integrate a gemini ai chatbot into your net API
Lucas Aguilera
About this gig
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). Clean, well-documented code you can actually maintain.
I also specialize in AI chatbot integration connected directly to your database using function calling (Google Gemini / OpenAI). Instead of generic AI responses, your chatbot answers real, specific questions about your own data like stock levels, availability, or order status pulled live from your database.
What I offer:
- REST API development in C# / ASP.NET Core
- JWT authentication & secure endpoints
- Database design and integration (SQL Server, EF Core)
- AI chatbot with function calling connected to your data
- Clean, documented, production-ready code
(Note: the AI chatbot feature requires your own Gemini or OpenAI API key for production use I'll guide you through getting one.)
Message me with your project details and I'll get back to you with a clear plan and timeline.

I'm a Higher Technician in Software Development specializing in .NET backend technologies, including ASP.NET Core and Entity Framework Core — demonstrated through personal projects like a REST API for inventory management with JWT authentication. I also have hands-on experience in AI prompt engineering and chatbot design from a professional internship, including sentiment detection logic and escalation flows. I'm currently seeking my first professional opportunity to apply these skills in backend development and AI integration.

FAQ
Do I need my own Gemini or OpenAI API key?
Yes, you'll need your own API key for production use. It's simple to get and I'll guide you through the process — it's free to start and only costs based on usage
Can the chatbot connect to my existing database?
Yes, I can connect it to your existing SQL Server database, or help design a new schema if you don't have one yet.
What can the chatbot actually answer?
It depends on the package — from a single type of query (like stock levels) to multiple functions and even simple actions, using function calling to pull real data from your system in real time.
Do you provide the source code?
Yes, full source code is included with all packages.
