What I'm looking for

I am seeking backend roles focused on scalable API development, performance and database optimization within collaborative teams that prioritize reliability, clean architecture, and career growth.

I am a PHP backend developer with 5+ years of experience building scalable, secure web applications for high-traffic systems and e-commerce platforms. I specialize in API architecture, backend optimization, and maintainable system design using Laravel and Symfony.

I've delivered backend services and REST APIs across international and local teams, implemented secure authentication including multi-factor authentication, and optimized database performance for transaction-heavy environments. I focus on reliability, performance, and clean, collaborative engineering practices.
