The standard has changed: teams that know how to build with AI are no longer working at the same pace as others. 🧠
I intervene precisely at this point: proven React / TypeScript / Python stack, solid technical foundation, targeted automation, and senior supervision to move faster without degrading the product.
I work on SaaS, business tools, dashboards, investment platforms, redesigns, V2, and custom products.
Recent references:
→ Fraktion: multi-product SaaS framework, white label, 35+ component design system, reusable architecture across 15+ platforms
→ Byyourside: CTO / Technical Lead, -40% AWS costs, 10,000+ simultaneous users, AI pipeline in production
→ Qonto: redesign of the web platform and onboarding process, high traffic
→ Mediapart: -40% on LCP, WCAG AA accessibility, high traffic
→ Assurmax: business platform from scratch, -50% processing time
→ Kaokeb: co-founded agency, 50+ projects for Allianz, Yamaha, France 2, Ministry of Education
Main stack: React, TypeScript, Next.js, Python (FastAPI, Django), Node.js, PostgreSQL, Docker, AWS.
I am particularly useful when it is necessary to:
- quickly launch a serious product
- take over an existing codebase and clean it up
- build a custom SaaS or business tool
- accelerate a team without degrading quality
- integrate AI in a useful way into a real product
