What I'm looking for

I am seeking backend or full‑stack roles where I can build scalable systems, mentor teammates, work in collaborative teams, and continue improving performance and CI/CD practices.

I am a PHP web developer with over six years of experience building and maintaining scalable web applications, specializing in backend development, API integration, and performance optimization.

I have worked across academia, e‑commerce, and enterprise projects, contributing to Magento 1.9 stores, university systems, and large real‑estate CRM platforms while mentoring junior developers and introducing code review practices.

My technical toolkit includes PHP, Laravel, Symfony, MySQL/PostgreSQL, Docker, CI/CD, and cloud platforms (AWS, Google Cloud), and I consistently focus on improving application efficiency and reliability.

I am passionate about continuous learning, delivering high‑quality solutions, and collaborating with cross‑functional teams to solve complex problems and drive product improvements.
