The problem

Research on hundreds of equities depended on data that arrived from many sources at different times. Analysts needed it collected, aligned and ready for modelling without manual work.

What I did

  • Acquisition and integration

    Built and automated a pipeline for real-time acquisition and integration of fundamental, strategic and price data.

  • Models and backtesting

    Developed Python statistical models for price-movement forecasts and systematically backtested strategies across market conditions.

Stack

  • Python
  • Statistical modelling
  • Backtesting
