Market risk, derivatives and energy trading, in Python · London

Website LinkedIn Photography

I was a trading assistant on ENN's LNG derivatives desk and then did an MSc at the University of Edinburgh. My open-source work is mostly risk and pricing tooling of the kind a desk runs every day. Each project is built end to end, runs on synthetic or public data, and is tested.

Risk and pricing

Project What it does
derivatives-risk-engine Daily market-risk batch for a multi-asset book: pricing, Greeks, full-revaluation VaR/ES, P&L explain, FRTB PLA and SA capital, loaded into Atoti cubes
otc-valuation-desk Independent price verification for GBP/USD rates and FX: OIS curves, own pricers checked against QuantLib, dealer-mark attribution
creditlab Corporate credit risk from SEC EDGAR filings: PD scorecard, ML and Merton models, portfolio loss, IFRS 9 ECL, Streamlit dashboard

Energy markets

Project What it does
energy-forecasting-to-dispatch Day-ahead price and probabilistic load forecasting fed into battery bidding, to measure what a better forecast is actually worth
power-fundamentals Solar and wind capture rates, negative prices, merit order and clean spark spreads for DE, ES and FR (2023–2026)

Tools

Project What it does
claude-skills Custom Claude Code skills: Typst documents, image generation, web image search, mind maps
qk-plot One plotting theme across matplotlib, seaborn, plotnine and cetz-plot, on the Tailwind palette
typst-component-library Typst component library: callouts, design tokens, theming and document presets
