Summary
Gerry Vandermaesen is an all-round PHP/Symfony consultant with over 20 years of hands-on experience and a track record of owning end-to-end delivery from requirements and UX to architecture and full-stack implementation. A certified Symfony expert and Zend Certified PHP Engineer, he excels at rebuilding legacy platforms, designing complex workflow engines, and shipping secure, auditable systems with PHP 8, Symfony, API Platform, and containerized deployments. He has led major migrations and productivity improvements for large clients like Proximus and designed travel and expense management platforms at Enabel featuring Azure AD SSO, async processing, fine-grained authorization and multi-language support. Comfortable as a sole developer or technical lead, Gerry combines product-minded UX redesigns with pragmatic engineering — for example transforming an outdated credit management interface into an efficient, modern platform. He actively experiments with AI-assisted development (Claude Code) to accelerate delivery and often integrates automation and CI/CD to raise team velocity. Based in Brussels, he brings rare continuity across consulting, product development and operational delivery.
