About this gig

AI Chatbots & Voice AI Built on Real Production Experience

I build AI powered chatbots and voice assistants using RAG (Retrieval Augmented Generation), OpenAI, Azure AI, and vector databases like Pinecone. As a Senior .NET Developer with 8+ years of experience, I integrate AI directly into real production applications, not just prototypes.


What makes my chatbots different:

Answers are grounded in your own documents (PDF, Word, or text), with source citations on every response, so your bot never makes things up. Each client's data stays fully separated and private.

What you get:

  • Document upload and processing
  • Vector database setup for accurate retrieval
  • Chat widget with source citations
  • Multi agent workflows using LangGraph and Semantic Kernel
  • Optional voice AI pipeline (speech to text, RAG, text to speech)
  • Clean, production ready dotnet backend


I currently lead AI orchestration for a live Voice AI product, so this is proven in production, not just theory. I also bring 8+ years of full stack dotnet, React, and Azure experience to build reliable, maintainable solutions.

Let's discuss your project I'll help you figure out the right approach.
