During October 2024, Andrey Pryakhin focused on streamlining the otusteamedu/PHP_2024 repository by removing outdated Docker and Nginx development environment configurations along with an auxiliary text file. Leveraging skills in Docker, Nginx, and system configuration, Andrey targeted the elimination of artifacts that contributed to environment drift and maintenance overhead. The cleanup established a more consistent baseline between local and CI environments, reducing onboarding friction and simplifying future changes. All modifications were delivered as a focused, low-risk commit, reflecting a methodical approach to repository hygiene. The work demonstrated depth in environment management and attention to long-term maintainability.
