- Technical experience: scoping, code review
- Dual PHP/Symfony + Go expertise
- Quality focus: testing, PHPStan, clean architecture
- Strong curiosity for AI applied to development
- Quick integration into agile teams
🚀 Available for team reinforcement, technical lead, or on AI architecture and integration topics.
