About Damien

Audit, modernization, and security of critical Drupal and PHP applications. Methodical diagnosis, progressive migration plan, refactoring under test coverage, without service interruption.

With over 15 years of experience on complex PHP architectures (Drupal, WordPress, Symfony, Laravel), I have supported projects for clients such as BNP Paribas, RATP, Mercedes-Benz, and the French Academy of Sciences.

My approach: a methodical audit (static analysis, architecture review, migration plan) followed by progressive, brick-by-brick modernization.

My added value:
  • Audit & Diagnosis: precise identification of security vulnerabilities, performance bottlenecks, and technical debt. Clear, decision-oriented deliverables.
  • Progressive Modernization: Drupal migration (D7/D8 > D10/11), PHP version upgrades, architecture refactoring, decoupling monoliths. Each intervention is secured by test coverage guaranteeing zero regressions.
  • Performance & Security: reduction of server costs, acceleration of response times, hardening of production security.
  • Consulting Posture: ability to translate technical challenges into business risks and opportunities for your decision-makers.

Technical Stack: PHP 8+, Drupal 10/11, WordPress, Symfony, Laravel, hexagonal architecture, Docker, AWS, CI/CD.

Artificial Intelligence: design and deployment of LLM agents in production. RAG integration, orchestration of multi-tool AI workflows - Claude Code, OpenAI, Supabase, Pinecone, LangChain, n8n.
