    TroveInvest

    • Engineered a pipeline that extracts, normalises and standardises logistics-asset data from heterogeneous document formats.
    • Re-engineered the Python analytics pipeline for commercial real-estate leasing comparables: 100× faster through vectorisation, caching and a restructured data model.

  4. May — Jun 20242 mo

    URENCO

    • Simulated transient heat diffusion in industrial storage cylinders with finite differences to find their thermal-stability limits.
    • Modelled constraints on nuclear fuel-cycle components; regression on experimental data lifted electrolytic yield from 70% to 85%.

    CERNLHCb

    • Wrote control software coordinating the vacuum systems for experiments on the LHCb VELO detector.
    • Automated the measurement workflow so detector-level data could be reproduced, and wrote the results up for the collaboration.
