Quentin François

Are you launching or evolving a SaaS product and need someone who doesn't just execute tickets?

I support founders and early-to-mid stage teams in designing, structuring, and delivering their product, from technical architecture to user interface.

I step in when the stakes go beyond simple execution: architectural choices, product prioritization, long-term quality, and delivery speed.

Specifically, I have already taken products from 0 to 1 with teams of 1 to 4 people, supported founders on scalability and architecture issues, and led migrations from legacy code to modern stacks to establish truly sustainable foundations.

My role is to take a high-level view of the product and stack to avoid costly mistakes in the early stages.

I combine advanced frontend expertise (React / Next.js / TypeScript) with a global product vision to build maintainable, scalable technical foundations aligned with business objectives.

· Structuring or taking over the product roadmap

· Frontend architecture choices and technical trade-offs

· Establishing solid foundations (design system, standards, DX)

· Accelerating delivery during critical phases

· Auditing and supporting complex or growing projects

I often act as a part-time CTO or product lead when full-time recruitment is not yet relevant.

I also support founders and teams in skill development, technical decision-making, and product / time-to-market / technical debt trade-offs.

Interested?

Let's discuss your context and see if I'm the right person to support you.
