About Philippe

The right fit?

Lean CTO, results-oriented, I intervene in contexts where technical debt, instability, slow delivery, or security risks hinder team growth and performance.

My leadership style is based on empowerment, clear priorities, and teamwork. I quickly help teams regain control of their system: less chaos, more flow, more value delivered.

CTO and co-founder of several startups, former developer then Product Manager, I have a deep understanding of business, product, and technical challenges, and I systematically align technology with strategic objectives.

My added value

My role is to transform fragile or underperforming technical organizations into reliable, secure, and predictable systems capable of delivering quickly without sacrificing quality.

I bring a Lean Tech approach:
waste reduction, continuous improvement, clear standards, flow and data-driven management.


I intervene on:
  • Clarifying business, product, and tech vision
  • Massive reduction of technical debt (structural, organizational, cognitive)
  • Accelerating delivery (time-to-market, throughput, reliability of production releases)
  • Implementing robust standards: quality, security, architecture, engineering practices
  • Securing systems (processes, governance, security debt)
  • Continuous improvement and waste reduction
  • Aligning multi-disciplinary teams (tech, product, design, data, CRM)
  • Recruitment, skill development, and talent retention
  • Implementing structured continuous improvement (Lean, Kanban, flow indicators)
  • Communication within and outside the team
  • Building and deploying pragmatic Product & Tech strategies
  • French

This collaboration with Philippe has been very satisfying at all levels. Philippe came to our aid, at short notice, during a busy period for us on critical payment issues. He quickly immersed himself in the code and our organization. He then worked on related topics concerning our booking and visit management. We worked together in a perfectly fluid, transparent, and efficient manner. It was a pleasure!
