Back to original languageAbout Guillaume
Freelance back-end developer, I strengthen the technical teams of web agencies on e-commerce projects and business applications.
My specialty: Prestashop, Symfony, Laravel. I work on custom modules, API integrations, performance optimization, maintenance, and evolutions.
In concrete terms:
Independent since the end of 2019, 3 years of active collaborations with several partners
Dailies, sprints, code reviews, Git flow: I adapt to your workflow
French business hours (9 a.m. to 6 p.m.), no time difference to manage
Recurring subcontracting, NDA and confidentiality without issues
I appreciate long-term collaborations, but I also intervene on a case-by-case basis when the need is clear.
Currently available for new missions, remote anywhere in France from Haute-Savoie.
