Worked on targeted documentation enhancements for the margelo/expensify-app-fork repository, focusing on improving onboarding and transaction processes for users. Leveraged technical writing and content development skills to clarify Canadian EFT routing number requirements, streamline mobile-first onboarding documentation, and update 2FA and account recovery links. Used Markdown to ensure clear, accessible documentation and collaborated across teams to align with evolving product strategies. The updates removed outdated desktop references, provided step-by-step guidance for American Express production file submissions, and reduced user confusion. This work contributed to a smoother user experience, minimized support requests, and accelerated processing cycles without introducing new bugs.
