Cornel Andreev

PHP Backend Engineer & System Architect

I build robust backend systems and APIs with PHP, specializing in Symfony, Drupal, and enterprise content platforms. I turn complex business requirements into maintainable, scalable code—from high-traffic web applications to serverless architectures on AWS and Cloudflare.

My expertise spans RESTful API design, system integrations (CRMs, SSO/OAuth, payment gateways), and modernizing legacy applications. I have extensive experience with user-heavy and data-intensive web applications, including background processing with queues and cron systems. I'm well-versed in architectural patterns like DDD, CQRS, and TDD.

I've delivered projects for universities, healthcare organizations, and e-commerce platforms across Europe and the US—working on LMS platforms, complex data migrations, and leading full-stack development teams.
