Android Staff Engineer @ Qonto
I build the banking app European SMEs & freelancers rely on every day. These days I obsess over Jetpack Compose and bringing AI into the Android team. For over a decade I also helped grow the Paris Android community.
Bringing AI into how Qonto's Android engineers work: agents, tooling and workflows that make the whole team faster and ship with more confidence.
Driving the migration of Qonto's 100+ remaining XML screens to Jetpack Compose, modernising a large, real-world codebase without slowing delivery.
✍️ Article coming soonEight years on one Android app, from the first Compose screen to leading the migrations, tooling and AI that move the whole team forward.
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.
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.
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.
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.
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.
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.
From accelerometer games on early phones to a banking app trusted across Europe.
Building the banking experience for European SMEs and freelancers. I shape Android architecture, lead the move to Jetpack Compose, and bring AI into the team's day-to-day engineering.
Built Android apps for major clients and led Scrum & Kanban teams. Deep dives into the Android platform, AOSP and device-level quirks, plus the agile craft of helping teams ship.
Co-organized the Paris Android User Group, Droidcon Paris and AndroidMakers for over a decade, helping grow one of Europe's most active Android communities.
Engineering degree from the Institut Supérieur d'Électronique et du Numérique, where the first side projects (and the AcceSnake obsession) began.
Side projects and apps across phones, presentations and playful weather.
A fun, educational weather app for children and families. Playful, safe, and privacy-first by design.
Show your slides on an external display over Miracast/WiDi while you control the deck privately from your phone.
Accelerometer-controlled Snake for the Nokia N95: tilt to steer. Grew to 200,000+ downloads in its heyday.
Share information across Android devices on the same network using Network Service Discovery and pseudo-intents.
Libraries, experiments and conference projects, from sliding menus to AndroidMakers tooling.
