Skills

Strong technical skills serving useful and sustainable systems.

For more than 15 years, I have been working on professional web applications: business platforms, CMSs, APIs, internal tools, existing systems and projects with complex business logic. My approach combines backend expertise, deep system understanding, pragmatism and effective collaboration.

What I Bring in Practice

Backend Development

PHP, Symfony, Drupal, REST APIs, integrations, business logic, maintenance and evolution of existing applications.

Complex System Understanding

Analysis of existing codebases, application architecture, data flows, service dependencies and production constraints.

Incremental Improvement

Targeted refactoring, stabilization, technical debt reduction, testing, code readability and sustainable evolution.

Communication & Support

Clear explanation of technical decisions, team collaboration, mentoring, coaching and knowledge sharing.
