What this is
Built to be inspected
I design and ship production web platforms for product teams that need reliability without bureaucracy. Ten years across fintech, logistics and health — now consulting independently through Atelier PEP. Atelier PEP is a portfolio that runs like a product: typed end to end, validated at every boundary, and observable in production. The public pages are the pitch; the client dashboards behind them are the proof.

“Design handoff stopped being an argument. The token package meant the build matched the intent without a review cycle for every spacing value.”
Daniel Weiss · Product Design LeadMeridian Digital
“We stopped losing telemetry and, more importantly, we could finally see when something failed. That visibility paid for the project twice over.”

“The fleet dashboard changed how our dispatch team works — issues are visible, reports are automatic, and the mobile experience finally works.”
