About this gig

Get an app your team can actually use, not a notebook. I design, build and deploy web apps in R Shiny, Streamlit or Python with AI built in: users can ask questions of their data, summarize documents, and run forecasts or scenarios.


WHAT I DELIVER

  • Interactive apps with filters, charts, uploads and downloads
  • - AI features using OpenAI or Claude APIs: chat with your data, document Q&A, automatic insights
  • - Built-in models: forecasting, scenarios, scoring
  • - Connections to Excel, PostgreSQL, ClickHouse, Databricks or APIs
  • - Cloud deployment, with clean, documented code

WHY ME

  • Built a production emissions forecasting and portfolio app in R Shiny for a US climate company
  • - Data pipelines on Databricks and AWS for European and US clients
  • - Senior Data Scientist and econometrician; Upwork Top 3%, 120+ projects

Send me what your users need to see or ask, and I'll scope it before you order.
