About Virgile

Firefighter or captain: depending on what you need.

Accustomed to navigating the storm, I arrive quickly, understand the stakes, and free up your time and mental load on one or more projects. Alone or alongside your CTO, I adapt to what is already in place. Efficient and direct: I bring the project to a successful conclusion.

What I've already done

Several dozen digital products designed, delivered, and put into production, from MVP to complete SaaS portal, on projects up to €350k and multidisciplinary teams of 14 people. As a freelance CTO, I transform an idea into a concrete product: internal tool, web platform, mobile application, or prototype to validate a concept before investing further.

How I work

Product vision, technical understanding, and rapid execution. I design and evolve solutions in a few days where others take months if the goal is to move fast.
If the idea is to build a product very quickly, I design and build your solution very quickly using modern tools (extensive experience with agentic systems and AI for development).
If I need to lead your teams, prioritize, and make decisions, no problem, I adapt and act.

What I manage end-to-end

  • Strategic framing and prioritization
  • Technical architecture and product choices
  • Team/supplier coordination and budget control
  • Operational delivery and post-launch monitoring

An idea to validate quickly? A product to launch? A project that's going off track and needs to be secured? Let's talk, average response time **under 1 hour**.
