Yoann AbrielGeneva / Lausanne, Switzerland

From marketing to AI engineer.

I was hired at Orange to do marketing. I taught myself to build, and turned my own role into an AI engineering one: nobody handed it to me.

Now I build production GenAI by day and my own products at night. I care about one thing most: making AI you can actually trust, not AI that just looks good in a demo.

I finish my Master's at Epitech in 2026. Until then, I let the work do the talking.

Right now
Fovea, an iOS speed-reading app (RSVP), under construction.

How I work

I ship end to end

Idea to production, alone if I have to. Frontend, backend, infra, payments: I hold the whole chain.

I evaluate, I don't trust vibes

"It feels good in the demo" is not a number you can ship on. I test my outputs against real cases.

I learn fast and go deep

The Epitech piscine every year. I even trained a small language model from scratch, just to understand how they work inside.

I enable others

RAG workshops for PMs, mentoring interns, reusable patterns. What I build should be useful beyond me.
