Summary
🤩
Rockstar🎓
Top SchoolRomain Canon is a seasoned software architect with 11 years of experience designing and delivering robust web systems, currently shaping platform architecture at Vattenfall from Lyon. He specializes in PHP backend engineering and CMS-driven architectures, having led strategic reworks for large-scale sites at Total Direct Energie and contributed backend improvements to the TYPO3 core. An active open-source maintainer, he leads Valinor, a library for mapping inputs to strongly-typed PHP value objects, and regularly fixes subtle type-parsing and performance issues in prominent projects. His work combines pragmatic refactoring (e.g., performance-minded use of static::class) with careful handling of data mapping and type safety across complex information systems. Comfortable in both enterprise and agency contexts, he brings a mix of architectural vision and hands-on code hygiene that reduces technical debt while improving runtime behavior. Colleagues would note his attention to edge-case correctness in type handling—a detail that often prevents production surprises.
