AI & software engineering
LLM-assisted workflows, multi-model systems, and production software, from Python data tooling to C#/.NET systems.
Data pipelines & research tooling
PySpark and Parquet pipelines, and browser-operated research instruments used by researchers at 8+ European universities.
Digital transformation for organisations
Consulting for SMEs and non-profits: automated business-intelligence reporting, data-capture tooling, and internal pipelines that cut manual work.

MAGI: a deliberative multi-LLM councilThree LLMs answer in parallel, then, optionally, review each other's anonymised responses and revise. A rapporteur writes the synthesis; the lowest-confidence model writes the minority report. Open-source Python, eight decision methods, live at magi-council.org. -
UK local elections 2026: a forecast comparatorA static, interactive site comparing eight published forecasts of the 7 May 2026 UK local-election seat outcomes against the actual result. Four ways to read the same data, transparent dated provenance, recomputes three of the eight from current polling against a 2022 baseline. Live. -
