Back to original languageAbout Quentin
Tech Lead / Architect evolving towards a CTO role, I build complex tech products from scratch (0 to 1), with an approach focused on architecture, reliability, and delivery.
My background was forged in demanding environments — SaaS, healthcare, public sector, critical systems — where software quality, security, and maintainability are not optional.
What I bring:
• Think architecture before implementation, build solid foundations to prepare for scaling.
• Transform business complexity into concrete and maintainable solutions.
• Reduce technical debt rather than accumulate it.
• Support and upskill the technical team.
• Align product roadmap, architectural choices, and delivery.
My interventions go beyond code: architectural choices (back-end, front-end, microservices, data), technical debt audit and reduction, delivery process structuring, recruitment, and tech coaching.
I aim for an early-stage CTO role or a tech co-founder position, in a B2B SaaS startup or a complex business product to build and scale. In the meantime, I freelance on high-stakes technical missions: structuring a product from scratch, architecture redesign, team support, or legacy system takeover.
