Full Stack Developer to Build an AI Feature for SaaS MVP using C#/.NET, Python, React, OpenAI & RAG

Hi, I'm looking for a Full Stack Developer to add one AI-powered feature to an existing SaaS MVP. The idea is simple: users provide a document or business data, and the application uses AI to extract and structure the information, then trigger the next step in the workflow. The work includes: - Building the feature with C#/.NET, Python/FastAPI, and React - Integrating OpenAI API and implementing a focused RAG flow - Connecting the AI functionality to PostgreSQL and existing REST APIs - Adding basic workflow automation, validation, and error handling - Dockerizing the feature and deploying it to AWS or Azure AI The stack includes C#, .NET, ASP.NET Core, Python, FastAPI, React, TypeScript, PostgreSQL, REST APIs, Docker, AWS, Azure AI, OpenAI, RAG, LangChain, vector databases, and Pinecone. I'm looking for someone with hands-on experience in AI SaaS, Full Stack Development, MVP development, AI integration, and workflow automation who can take this feature from idea to a working implementation without over-engineering it. Please share a couple of relevant AI SaaS, RAG, OpenAI, or Full Stack projects you've built.
