Miguel González Calvo

Madrid, Spain

I'm a data scientist and AI engineer. I work at Banco de España, Spain's central bank, as an Expert in Data Science.

Before that I led AI engineering at A5 Labs, building systems around language models, after eight years across aerospace, geodesy and retail data — Airbus, Leica, toom, Pascual. I also teach economics, Python and blockchain at three universities, and keep building things on the side — a GNSS calculator, a Renfe train app, and small tools on live OECD data.

Projects

GNSS Calculator Web Time and coordinate conversion across GPS, Galileo and BeiDou, plus RINEX and NMEA inspection Próxima Parada iOS Live Renfe departures, platforms and delays on iPhone, Watch and Mac — an unofficial companion app

Tools
