Front to back, and the architecture in between.

Risk software, mostly, used every day by risk and portfolio managers. Equity factor analysis, backtesting, portfolio optimisation and PnL attribution, with scenarios and limits across VaR, Greeks and stop-losses.

Python and FastAPI, Java and SQL underneath, with Kafka, Redis and ArcticDB moving and holding the data, and Angular and React on the surface. Claude sits alongside, with agentic coding speeding up design, migration and review.

Outside of work, a side project on the UK housing market: a scorer that rates any location for a buyer, much like a credit score.

Places and pages

Travel tends to follow vistas, sunsets and open horizons, with a museum or gallery for the culture. A diploma in photography, and a shelf of art books brought home along the way.
