About

I'm a data engineer and analyst with a PhD in mathematics. I drive data-focused decision making, build analytics pipelines and tooling for Amberside Management Solutions - a renewable energy asset management company. On the side I make interactive visualisations of maths and physics, build simulations and work on AI/ML side projects.

Based in London, UK · Open to conversations about data, analytics, and mathematically-flavoured problems.

Career transition — academia to data

2020 – 2023

Retrained from pure mathematics into CS, Data and ML/AI topics through structured courses, self-study and hands-on portfolio work.
- Worked through the IBM Data Science Professional Certificate (Coursera), MIT's Introduction to Computer Science (OCW), and Stanford's Machine Learning course — lectures paired with the accompanying problem sets.
- Built a self-taught stack in Python, SQL, JavaScript, pandas and D3.js, applied throughout the interactive simulations and visualisations on this site.
- Sustained algorithms and data-structures practice via AlgoExpert.
- Continued teaching alongside retraining: ACT/SAT tutoring at Huntington Learning Center (2021) and freelance maths tutoring.
Lecturer — UC San Diego

2019 – 2020

Taught multivariable and vector calculus to undergraduate cohorts; some of the interactive visualisations on this site originated as teaching aids for those classes.
