Stéphane de Barbanson · founder● The studio
A one-person studio that ships like a team.
Twenty years turning messy data into clear decisions, first as an analyst and BI specialist, now as someone who builds the tools themselves.
As a PL-300 certified Power BI trainer I create dashboards, Power Apps and automated workflows. But I also build full web applications and native apps with React, Next.js and modern AI tools, a combination you won't find often.
I work best taking an idea from whiteboard to working product. No bloated teams, no endless meetings, just fast, focused delivery.
