Mariela Alvarez-Rueda developed two key frontend features for the Soft-Craft-Bol/Py-Academy repository, focusing on both user experience and development workflow. She implemented private routing for student sections and personalized the navigation bar to display each user’s profile information, enhancing security and engagement. To support reliable delivery, she established a continuous integration pipeline using GitHub Actions, automating build validation on feature branches and pull requests. Her work leveraged React, JavaScript, and YAML, demonstrating practical application of CI/CD and frontend development skills. The features addressed navigation security and regression risk, reflecting a focused, foundational contribution within a one-month development period.
