AI practitioner since 2017, context/harness engineering specialist. 12 years in tech, ex-CTO/VP Engineering, chose to go back hands-on. AI Founding Engineer @ Méthode Aristote (EdTech + AI)
Direct, kind, energetic. Always 8 projects running.
I write about AI-assisted engineering and keep my guides updated, most weeks bring something new.

AI since 2017: NLP and predictive ML in production at Q°emotion and eXplain (semantic search, sentiment scoring, ~30M articles processed). Generative and agentic AI daily since 2025.
12+ years: Developer → Team Lead → EM → VP Engineering → CTO → back to hands-on by choice.
Why hands-on? After a decade leading teams (4-150 people, managed up to 30 engineers), I deliberately stepped back to sharpen my technical edge. Leadership is more effective when grounded in current engineering reality. In the first 3 months of 2026, that bet produced 10+ open-source projects, 5,000+ stars on my own, plus core contributions to RTK (77,000+ stars).
Leadership experience:
- Built and scaled engineering teams from scratch (early-stage → Series A → scale-up)
- Shaped engineering culture, processes, hiring, mentorship
- Led across SaaS, E-commerce, Data, EdTech domains
Tech:
- Stack: TypeScript (Next.js 14+, Nest.js, tRPC), Rust, Ruby (Rails), Python, SQL/NoSQL
- AI: Claude, GPT, MCP server development, agentic workflows. NLP/ML since 2017 (Elasticsearch, spaCy, Gensim)
- Infra: AWS, GCP, Vercel, Docker, Kubernetes, serverless
- Domains: Fullstack (backend preference), product development, technical architecture
Formation: Computer Engineering @ UTT Languages: French, English
