Senior PHP Backend Developer · 20+ years shipping scalable, maintainable software.
Senior PHP backend developer specialized in Symfony, Laravel, REST APIs, microservices, and high-traffic e-commerce platforms (PrestaShop).
I cover the full development cycle: architecture, development, testing, deployment, and maintenance. I care about code quality, best practices (SOLID, unit testing, code review), and application performance. My focus: things that ship, perform, and keep working years later.
