About this gig

Need an AI chatbot that actually knows your business? I build custom RAG chatbots trained on your documents, so customers and staff get accurate answers instead of generic AI guesses.

I'm a principal data scientist who builds production AI systems for a living. I work with frontier models, local models, and Azure OpenAI, and deploy on Azure and AWS. I've shipped retrieval and recommendation systems in regulated fields like healthcare and legal.

What you get: a deployed RAG chatbot for your PDFs, docs, or knowledge base. Basic is a quick bot on a small doc set. Standard adds a branded interface, a bigger knowledge base, and deployment to your cloud. Premium adds a React/Vue frontend, CRM/database integration, user login, and multi-language support.

Want a custom, state-of-the-art build? I follow the latest retrieval research and use techniques like graph and hierarchical RAG, reranking, and prompt optimization (DSPy) for tailored solutions. Message me if an off-the-shelf bot won't cut it.

Note: every package delivers a deployed, working chatbot. Source code is included with Premium, and an add-on for Basic and Standard.

I'm a Principal Data Scientist with 7+ years of experience building production AI. I focus on RAG and LLM pipelines for regulated, high-accuracy work in healthcare and legal settings. I deploy across AWS (EKS, infrastructure) and Azure (Azure OpenAI, Azure AI Search), and build the full app around it with React or Vue frontends and Python backends. I also build agentic workflows with LangChain and LangGraph. My background is in applied mathematics, and I build things other people can maintain. Tell me what you're working on and I'll help get it running.
