Rigor and quality
I favor clean, robust, and maintainable solutions. The goal: to avoid quick fixes, recurring bugs, and hidden extra costs.
Advice and honesty
I help you make the right technical choices: what is relevant, what can wait, and what truly deserves your budget.
WordPress and PrestaShop Experience
I regularly work on existing sites, sometimes complex ones, to fix, evolve, or stabilize them without starting from scratch.
Smooth Collaboration
I work with seriousness, responsiveness, and transparency. You know the project's status, what has been done, what is blocked, and what the next steps are.
I can assist you in creating a website, evolving an online store, developing a specific feature, fixing a bug, or providing technical support as a subcontractor.
Looking forward to discussing your project.
