// Profile
I build the screens that sit between a live signal and the person responsible for it. Ground stations, playout suites, internal dashboards — places where the data never stops arriving and being wrong for two seconds is a real problem.
That work started at a regional broadcaster in 2018, maintaining a playout scheduler older than I was. It taught me the thing I still design around: operators do not read charts, they scan for the one value that has gone out of range.
Since 2022 I have worked independently from Bordeaux, mostly with broadcast and telemetry teams across Europe. Six clients, forty-odd shipped systems, and a standing preference for interfaces that survive being stared at for eight hours.
