About this gig

Want an AI chatbot that answers from your own documents, or automations that save hours of manual work? I build practical AI solutions with the OpenAI and Claude APIs.


What I can build:

- AI chatbots for websites and customer support

- Document Q&A chatbots (RAG) using your PDFs, docs or website content

- AI assistants inside your existing web app

- Workflow automation with n8n, Make and Zapier

- Connecting AI to forms, sheets, email and databases


Tools I use:

- OpenAI API, Claude API, LangChain

- Python (FastAPI) and Node.js

- n8n, Make, Zapier

- Firebase, React, Next.js


Why work with me:

- MPhil in Computer Science with published deep learning research

- Clear explanation of costs, limits and API usage

- Clean, documented code that you fully own
