Freelancer profile translated to English.

Description

20 years in the software industry. CTO at Lemon Learning (4→15 people), Harvy (from scratch). SRE consultant at Chanel. Senior Dev at Etsy.

Today I do one thing: Fractional CTO. I join startups and scale-ups for 3 to 12 months, 3 to 4 days a week.

Not audit, or not only. Not consulting from a slide. I read the code, I recruit with you, I make the decisions that no one else has the mandate to make.

Two typical situations where I can intervene:

→ No CTO yet: I lay the foundations (stack, team, culture, process)

→ Junior CTO or solo founder: I support them long-term.

In parallel, I'm building AFK.live — an AI-enriched press aggregator, the best monitoring platform. Because good decisions are made with an enlightened mind.

I designed and built AFK.live from scratch: a press aggregator that analyzes headlines from 250+ sources in real-time using NLP models (BERTopic, SetFit). The product generates AI-enriched thematic dossiers, topic tracking over time, and an emergence score per topic. Full stack: Astro, FastAPI, Docker, Scaleway, Mistral, Qdrant. AFK is both an impact project (fighting filter bubbles) and my production ML experimentation ground.
