HelloHealth is an Electronic Health Record (EHR) application that I work on as part of the Myca Health development team in Québec City.
I have contributed to addressing the technical debt of a 200,000+ SLOC legacy code base, including rebuilding large parts of the frontend from Flex to Backbone/HTML and making components that were previously US-only functional in other markets as our business expands. This included things like different postal code and phone number formats and validation, as well as constructing certain views to include or remove fields and options based on what is required in a particular country.

Example of zip code validation. The component was built so that the validator updates if the user selects a different country. This change is effectuated without needed to refresh the page
