Hello 👋
Part-time CTO & Software Architect
I help companies structure, secure, and scale their digital products — from strategic planning to production.
As a transition CTO, solutions architect, and senior developer by training, I work withSMEs, scale-ups, large corporations, and technical teamswho need to:
- make good technical decisions,
- make an existing platform reliable or refactor it,
- accelerate without creating technical debt,
- structure or strengthen a tech team.
My background as a developer (primarily back-end, with a strong front-end culture) allows me to **remain very practical**, close to the code and the business objectives.
- Part-time CTO / interim management
- Technical & strategic audit, with actionable recommendations
- Software & API Architecture
- Taking over, migrating, or refactoring legacy code
- Developing complex web applications
- Strengthening or building technical teams (recruitment, profile selection, coaching)
- Coaching leaders on technical and strategic choices
I make it a point of honor to **anticipate risks**, simplify complex topics, and propose pragmatic solutions adapted to your real context.
As a developer since my teenage years, I have been designing and developing web applications since 2005.
My career has led me to work on:
- business software (point of sale, invoicing, inventory, ERP, CRM),
- complex websites and e-commerce platforms,
- high-growth startups, including an e-commerce project generating tens of millions of euros in revenue,
before fully dedicating myself to a CTO role since 2020.
