January 2025: Delivered two high-impact updates across repositories, strengthening environment reliability and test stability. Upgraded Ruby to 3.4.1 in lockers and study spaces configuration to ensure consistent runtime environments and reduce deployment risk. Refactored the Barcode API endpoint and stabilized tests by removing the index action, updating routing, and using stubbed Alma API calls, resulting in more reliable CI and faster feedback on barcode functionality. These changes improve operational stability, enable faster feature iteration, and demonstrate growing proficiency in Ruby/Rails tooling and test automation across teams.
