About Jean-François

With 20 years of PHP/Symfony experience, I intervene where it truly matters: technical architecture, legacy migration, critical project management, and AI integration into your development processes.
I work as an outsourced CTO — I take charge of the technical vision, architectural choices, and team management, without the commitment of a full-time hire.
My areas of intervention:

Migration and modernization of legacy PHP applications to Symfony 7
SaaS architecture and complex business applications
AI integration into development workflows (Claude Code, LLM, automation)
Technical audits and CTPO support

Available for full remote. Short or long-term assignments.
