Data Analytics & Applied AI

I build data products and AI tools — from ML classification models and trading bots to RAG pipelines with LangChain and OpenAI.

Current focus:

  • Building projects in analytics and applied AI — ML models, trading systems, and RAG pipelines.
  • Packaging them into usable tools — deployed on Streamlit with live demos anyone can try.
  • Documenting the process through GitHub and technical writing on Medium.
