PROFILE
Dung Pham - Jeff
Over a two-month period, contributed to LifeSG/web-frontend-engine by enhancing phone number parsing and stabilizing form submissions. Improved the getParsedPhoneNumber function to handle space-free inputs using libphonenumber-js, adding unit tests to ensure formatting-agnostic parsing and reduce user input errors in booking workflows. Later, addressed a bug in MultiSelect and NestedMultiSelect components by defaulting empty options arrays and optimizing value updates with a deep compare effect hook, which reduced submission failures. Demonstrated proficiency in JavaScript, TypeScript, and React, applying test-driven development and defensive coding practices to improve data integrity and user experience in complex frontend flows.
