I build production data science systems for shared mobility, delivery, banking, and finance.

At Yulu, I build the production models and operational systems that place bikes and batteries across cities, forecast real-time demand, and measure whether fleet decisions worked.

I also develop optimisation systems that guide field staff on which bikes to attend to, how to sequence work, and how vans should be loaded and routed. My work includes predicting part failures, planning spare inventory, and identifying repairs that last.

Previously at Experian, I developed credit scorecards that improved Gini by 10–15 percentage points, migrated credit-report generation from SAS to Python for a tenfold speed improvement, and built OCR for identity-document processing.

My earlier work spans banking and finance modelling, image and text analytics, and six years of condensed-matter theory research using advanced mathematics and Monte-Carlo simulation.

Senior Data Scientist

Jan 2020 - Present (6 years 8 months)

- Fleet demand and allocation: Responsible for the models that decide where bikes and
batteries are placed in each city, including a real-time demand forecast in production since
2021, and for the measures used to judge whether those decisions worked.

- Optimisation of field operations: Responsible for the systems that tell field staff what to do
next – which bikes to attend to, in what order, an

Data Scientist

Nov 2018 - Dec 2019 (1 year 1 month)

- Credit scorecards were developed to identify customers likely to take a personal loan or credit
card, improving on the models then in use by 10–15 percentage points of Gini.

- Credit-report generation was migrated from legacy SAS to Python, and made ten times faster.

- Optical character recognition was developed to read identity documents and fill in online
