Worked on stabilizing the manual transaction workflow in the callstack-internal/Expensify-App repository, focusing on reducing user friction during data entry. Addressed a bug by reverting a previous change that required merchant information after the amount input, thereby removing the merchant step and streamlining the manual transaction process. Utilized React and TypeScript to implement the targeted fix, ensuring that the adjustment preserved data integrity and did not introduce regressions. Conducted quick validation to maintain existing validations and overall workflow stability. The work demonstrated attention to user experience and careful regression management, leveraging strong front end development skills with JavaScript and TypeScript.
