Konstantin Gorin developed a comprehensive automated regression testing suite for the Insomnia-IT/feed repository, focusing on core features such as pagination, meal operations, badge management, custom field operations, user management, and QR code scanning. He established a robust CI/CD pipeline using GitHub Actions and Docker, ensuring consistent and reliable test execution across environments. Leveraging Python, Pytest, and Selenium, Konstantin created a Dockerized testing framework that supports scalable development and safer releases. His work laid the groundwork for faster feedback loops and improved release reliability, demonstrating depth in test automation and infrastructure within a focused, high-impact engineering effort over one month.
