At Digital University UA, I build Yii2 HR and university-management modules that digitize paper-based workflows for more than 15,000 users. I optimized critical database-heavy pages from approximately seven seconds to under 900ms and replaced manual statistical tracking with automated analytics and reporting.
I've also built Symfony backend functionality for an e-commerce platform, including XML supplier-feed synchronization for around 60,000 products, RESTful dropshipping workflows, Redis caching, and MySQL schema design. Through EPAM PHP Laboratory, I strengthened my experience with Symfony, Doctrine, Twig, Prometheus, Grafana, and load testing with Grafana k6.
