What I'm looking for

I seek remote-first roles building Laravel+React apps or enterprise ecommerce systems where I can modernize legacy platforms, apply TDD, and contribute to cross-functional teams with autonomy and reliable delivery.

I am a senior full-stack developer with over a decade of PHP and JavaScript experience, focused on ecommerce platforms, CMS systems, and backend infrastructure. I have recent enterprise experience extending Adobe Commerce (Magento 2) with custom modules and scalable architecture.

My background includes building custom CMS platforms, automation systems, and third-party API integrations; operating a multi-tenant affiliate and email platform at scale; and managing large server fleets and security administration for hundreds of white-label sites. At the enterprise level I supported multi-store Adobe Commerce builds, REST microservices, asynchronous queues, and CI/CD pipelines.

Currently I focus on modern Laravel + React applications, test-driven development, and legacy modernization while delivering reliably in remote-first, cross-functional teams.
