I will add ai chat and openai features to your web app


About this gig
Need AI in your app, or a web app someone actually finished? I build both.
I'm a .NET full-stack developer working with C#, ASP.NET Core, SQL Server and Vue/React. Most of my recent work is adding AI to existing products: chatbots, document search, and LLM features that plug into what you already have.
What I can do for you:
- Add an AI feature to your existing web app (OpenAI, Azure OpenAI, Claude, or any LLM API)
- Build a chatbot for support, sales or internal use
- Build or extend a functional web app
- Fix and improve an app someone else left half-done
How I work: we start with a short chat. I'll tell you honestly if it's a good fit and what it costs, then build in small steps and show progress, so nothing is a surprise at the end. You get clean, readable code and the source files.
FAQ
Q: Which AI providers do you use?
A: OpenAI, Azure OpenAI, Anthropic, or open-source models via API. If you already have one, I'll use it.
Q: Do I get the source code?
A: Yes, on Standard and Premium. On Basic it's a small add-on.
