I've worked across eight SaaS products at Icarus, product owner on one of them. Some are still looking for their market, others have millions of users, and each runs its own stack. AI is a big part of what I do there: I integrate LLM APIs and build automated content pipelines, and I brought down the cost and usage of the models across the company's tools. I don't only ship tickets. I weigh in on the product, dig through the A/B tests, and sometimes say a spec doesn't hold up.

A year of frontend work at Luvi (formerly Club), a social network for creators. Short cycles, continuous integration, near-daily releases. I ran the A/B tests and argued the results out with the product team. That's where I started folding AI into the way I work.

I co-founded Sheeriz and coded it from scratch: an app for women to make new friends. Real-time chat, voice messages, media sharing, events. We reached 180,000 registered users, hit #1 in Lifestyle on the App Store within 48 hours, and #22 overall.

I brought Moha in-house, a health and wellness app an agency had been building until then. Refactoring, a new design system, a rewards system, a dashboard. It's a medical product, with the quality and compliance constraints that come with one.

I built Storylation from scratch, a social network in Expo: feed, groups, private messaging, notifications, and text, voice and video posts. Redux and Redux-Saga to hold the async state, Pusher for real time.

Petit Agneau tells audio stories to children aged 6 to 10: audio books, matching text, a quiz per story. I built the AI pipeline that writes the stories, wired up the subscription, and handled the compliance a platform for children demands.

A book club needs a shared reading calendar, group discussions and progress tracking. That's what Shelfmate does, with threads split by chapter so nobody gets spoiled.

I learned to code at Epitech, in Lille. Three years of C and C++: games, a shell, low-level things. I specialised in web and mobile after that. Bachelor in Information Technology.
