About Bastien

Looking for a developer who can handle your web project from start to finish, from design to deployment? I design custom websites and applications in PHP/MySQL and JavaScript, with a back-office adapted to your business needs without dependence on heavy frameworks, for code that you can easily evolve over time.

What sets me apart: a rare dual expertise, between web development and hardware diagnostics/repair, which allows me to intervene on your application projects as well as your infrastructure issues. I also master AI content production workflows (video generation, voice-over), for innovative deliverables like training modules.

Autonomous, rigorous, used to managing a project as a whole (scoping, planning, client progress updates), I adapt to one-off missions as well as long-term collaborations.
