Lead developer, Sylius architect and founder: fifteen years of real-world systems.
From SFR to Edenred, through Vallourec and Capgemini — a coherent technical trajectory that underpins Keyson's practice.
Moustakime Kifia
I started my career automating network equipment monitoring at SFR, before progressing toward increasingly complex architectures in energy, telecoms, finance and heavy industry. Fifteen years of real projects — not just theory.
My specialty crystallized around Symfony and Sylius: I designed and delivered a B2B e-commerce platform at Vallourec (world leader in industrial tubes) and currently coordinate the redesign of a Sylius platform at Edenred with a NestJS BFF and a Next.js frontend.
Keyson extends this practice: defensible architecture, readable code, direct collaboration with your teams. First conversations happen with me — no intermediary.
