Back to original languageAbout Clément
I ensure the development, maintenance, takeover, and evolution ofSymfonyapplications andSyliusstores.
My specialty: application maintenance (TMA) forSymfonyandSyliusprojects — transforming an unstable app into one that can be evolved serenely.
How I work:
→ Audit first. I don't touch anything until I understand. You'll leave with a quantified roadmap, even if we don't work together.
→ Stabilization through tests + CI. On my latest assignments (custom Symfony platform, high-volume Sylius stores), it was the automated test coverage that allowed new features to be added in record time while stabilizing the platform.
→ Serene maintenance. Corrective and evolutionary maintenance, firm quotes, requests studied before commitment, direct communication.
🎯 My expertise
- Application maintenance (TMA) · Business application · E-commerce

What I work on:
- Third-party application maintenance (TMA): corrective + evolutionary
- Takeover of existing Symfony / Sylius code and applications
- Symfony version upgrades and migration
- Implementation of automated tests and CI
- B2C, B2B, marketplace stores (Stripe Connect)

Why my clients return: 80% of them had a bad experience with a provider before me.
With me: firm quotes, quality of production maintained, and a senior contact who assumes technical responsibility.
