Over a two-month period, contributed to the telus_online_test_system repository by delivering three frontend features focused on user experience and workflow efficiency. Developed a dedicated testing route with timer-enabled UI, section navigation, and question display supporting code snippets and multiple-choice options, as well as a candidate management interface with CRUD operations, sortable tables, and modal dialogs. Enhanced the user invitation flow by adding loading indicators and confirmation dialogs to prevent duplicate submissions and improve onboarding reliability. Emphasized modular component design, consistent feedback mechanisms, and atomic commit practices using React, Material-UI, JavaScript, and CSS to ensure maintainable and traceable code.
