I've seen too many freelancers, founders, and office managers lose sleep over unpaid invoices. Or worse, damage client relationships just trying to get paid. After 10+ years building software for others, I decided to tackle this one myself.
That's why I'm building Yetty.
An invoice follow-up tool that's smart, human, and kind. It reduces payment delays by 40%, saves 80% of follow-up time, and prevents 90% of disputes. No debt collectors, no awkward emails. Just the right message, at the right time, with the right tone.
I was a core team member of Storybook from 2019 to 2022. I shipped features, improved CI/CD pipelines, and helped shape the roadmap of a tool used by thousands of teams. That's where I learned what it takes to build something people actually rely on.
I spent 3 years at Gravitee, working on their core API Management platform. I shipped new features, merged tightly coupled repositories into a monorepo, set up visual regression testing with Chromatic, and reworked the release process to go from 1 day to 20 minutes. I also revamped CI pipelines to integrate all automated tests across projects.
I'm a part-time teacher at my alma mater, Mines Saint-Etienne (cycle ISMIN). I run two courses for Master's students:
| Course | What we cover | |
|---|---|---|
| 🌐 | Web Development | TypeScript, NestJS, MongoDB, Cloud Deployment |
| 📱 | Mobile App Design | Kotlin, Android development |
Building the next generation of engineers is just as important as building products.
