Senior Backend Developer · PHP, APIs and e-commerce
I'm a backend developer with more than 20 years of experience building and maintaining web applications. I specialize in PHP, Symfony, Laravel, APIs and high-traffic e-commerce platforms, particularly PrestaShop.
My work covers the full software lifecycle, from architecture and implementation to testing, deployment and long-term maintenance. I value clear solutions, reliable delivery and codebases that remain easy to evolve.
