I'm a full-stack PHP developer with 10+ years of professional experience, specializing in Laravel, Symfony, and WordPress on the backend—paired with Vue.js and Tailwind CSS on the frontend to deliver clean, modern, and scalable applications. Throughout my career, I've built and maintained a wide range of systems including custom web apps, CMS-driven sites, and e-commerce platforms. My experience spans across: ✅ Laravel (including Filament, Nova, Queues, API development) ✅ Symfony (Doctrine ORM, modular architecture) ✅ WordPress (custom plugins, theme development, REST API) ✅ Shopware, CodeIgniter, Concrete5, Magento ✅ Frontend with Vue.js and Tailwind CSS ✅ MySQL/PostgreSQL, Git, Docker, Linux servers ✅ API integration (REST/SOAP, Sabre, internal services) I started my career in IT support, but through dedication and continuous learning, I transitioned into a full-time developer—working on high-traffic, business-critical platforms. After a short break from Upwork due to personal commitments, I'm now back and fully available for new long-term or short-term projects. I take pride in writing clean code, communicating clearly, and delivering results that align with business goals. 📅 Open to interviews, test tasks, or code reviews—let's build something great together.
