What I've built at Qonto
Eight years on one Android app, from the first Compose screen to leading the migrations, tooling and AI that move the whole team forward.

Compose pioneer & the QontoUI design system
2020
Long before Compose was anyone's default, I shipped Qonto Android's first Compose component and first Compose screen, about five months ahead of the next one. I also founded QontoUI, the design-system module and demo app the whole team still builds on today.

Android tech lead on flagship features
2020-25
I've been the Android technical lead on much of what Qonto ships day to day: Account Receivables ("Get Paid"), the Cashflow dashboard, e-invoicing across four countries' regulations, and every strong-authentication flow that keeps accounts safe.

Leading the Money migration
2026
Rounding bugs on money are exactly the 0.1% that quietly erodes trust. I led a small team (plus two custom AI agents I wrote) to move the whole app onto a type-safe Money type, across ~100 pull requests. No more cents-rounding incidents.

Killing the last XML screen
2026
I led the team, up to eight engineers, that migrated our last 86 XML screens to Compose across seven teams, in about eight weeks. We'd estimated twenty-nine. The trick: a self-improving orchestrator skill that got a little sharper with every screen it touched.

HTTP error tracking, everywhere
2023-25
Production issues get cheaper the earlier you spot them. I built an error-tracking framework that surfaces HTTP failures in real time, Sentry to Slack, and rolled it out across twelve teams, then spent a good while tuning out the noise.

Tooling & mentoring that scale past me
Ongoing
The work I'm proudest of multiplies other people. I built a copies-automation tool that cut content designers' workflow by 75% (~600 hours a year), and I've mentored around ten engineers, several onto the staff track.
