About

PHP Developer with over 10 years of experience, specializing in Symfony. I have built e-commerce systems, VOD platforms, and SEO tools.

I value clean code, thorough testing, and well-structured documentation.

Software Engineer

I'm an experienced PHP Developer with over a decade of hands-on expertise in building scalable web applications, APIs, and backend systems. My core strengths lie in modern PHP (8.x), Symfony, Phalcon, and ecommerce platforms like Sylius. I have a strong background in database design, Elasticsearch optimization, and integrating third-party APIs, including payment gateways and recommendation engines. Known for my clean, testable code and problem-solving skills, I thrive in agile environments and enjoy refining complex logic into maintainable solutions. I'm currently available for freelance or full-time opportunities where I can contribute to high-impact projects.
