Contributed to the liatrio/devops-bootcamp repository by developing comprehensive documentation and learning resources focused on design patterns and SOLID principles. Leveraging Python, the work included creating an overview page, detailed explanations with code examples, an interactive quiz, and three hands-on exercises that demonstrated SOLID concepts through complete Python projects. All exercises were validated with behavior-based tests and passed quality gates using pytest, mypy, and ruff. The documentation was enhanced with improved onboarding instructions, updated navigation, and configuration changes to streamline developer setup. This effort strengthened knowledge transfer, onboarding efficiency, and aligned project structure with established software design standards.
