Santiago Guridi developed and enhanced the subject planning workflow for the cedarcode/mi_carrera repository over seven months, focusing on both backend and frontend improvements. He implemented semester-based subject planning, modernized the UI with Tailwind CSS, and introduced a Choices-based subject selector integrated with Stimulus.js. His work included robust database migrations, schema evolution, and data integrity enforcement using Ruby on Rails and SQL, while also refactoring legacy code for maintainability. Santiago streamlined asset management with SVG icon updates and improved test coverage through RSpec and system testing. These efforts resulted in a more reliable, efficient, and user-friendly planning experience.

April 2025: Delivered core UI and test improvements in cedarcode/mi_carrera, focusing on user-facing subject planning enhancements and robust test coverage. Implemented Subject Planning Interface Enhancements to streamline partial rendering, enable two dropdowns for subject selection, and introduced an ordered_by_short_or_full_name scope to support forthcoming ordering features. Modernized the TreePreloader test suite by migrating tests to RSpec to ensure reliable preloading validation for subjects, courses, and prerequisites, including checks for persistence after destruction and name-based filtering. While no major production bugs were reported, these efforts reduce risk, improve user efficiency, and establish a solid foundation for future UX and data-driven improvements. Key technologies include Ruby/Rails, RSpec, and CI-friendly test design.
