About Benjamin

Freelance web developer for 8 years, specializing in PHP/Symfony and web security audits.
I undertake two types of missions:
  • Custom Web Development
Creation and maintenance of business applications (Symfony, API Platform, React, PostgreSQL). My specialties: refactoring legacy code, integrating third-party systems (ERP, CRM, payment), custom e-commerce platforms.
  • Security Audit
OWASP analyses, configuration reviews, prioritized recommendations. My clients are mainly SMEs and mid-sized companies that do not have an internal CISO and want a clear, actionable, jargon-free assessment.

Typical Interventions :

Complete refactoring of legacy sites, taking over struggling projects, creating custom REST APIs, web security audits, and GDPR compliance.
Senior full-stack profile with a DevSecOps approach (security integrated from the development stage).

Why Choose Me?

I say no to poorly defined projects and I don't charge for the initial consultation. My deliverables always come with documentation so your teams remain autonomous.

Based 20 minutes from La Rochelle, I work remotely across France and on-site in the La Rochelle / Niort / Bordeaux area.

Available for short missions (audits, team support) or long ones (well-defined projects).

First consultation is free.
