• Development and architecture: developing and maintaining a large-scale building and structure technical inspection system on Yii2 + PostgreSQL. Performing deep legacy refactoring and performance optimization of key modules.
• Platform modernization: successfully migrated the platform from PHP 7.3 to PHP 8.1. Implemented Redis caching and a RabbitMQ-based queue system for asynchronous processing of heavy tasks. Designed and rolled out a feature toggle system, enabling the move away from long-lived branches, eliminating complex merge conflicts, and adopting trunk-based development.
• Code quality: introduced automated testing with Codeception, substantially improving release stability and reducing regression errors as the legacy system evolved.
