What I'm looking for

I seek back-end roles focused on PHP/Symfony API development, reliable DevOps practices, collaborative teams, and opportunities to improve performance and deliver production-grade systems.

I am a back-end engineer with extensive experience building REST APIs and web applications using PHP, Symfony and related technologies. I have worked full-time, freelance and as a contractor on projects for insurers and varied clients, delivering tested, production-ready back-end code.

My background includes full-stack web development with WordPress, Prestashop, CodeIgniter, MySQL and front-end essentials (HTML, CSS, jQuery, AJAX). I apply DevOps and modern tooling—Docker, Kubernetes, Git, PhpStorm and PHPUnit—to produce maintainable, automated solutions.

I hold a Master's in Applied Engineering Sciences and a Bachelor's in Computer Science, and I bring strong analytical, research and teamwork skills. I look for roles where I can design reliable back-end systems, optimize performance and contribute to cross-functional teams.
