Professional Experience
Software Engineer @ Doordash2021 - 2022
DoorDash is a global online food ordering and food delivery platform
- When joining, the login and sign up page was minimally maintained, poorly tested, and lead to convoluted development.
- Took over the login and sign up web app and redesigned the internal code base to increase developer velocity by 60% and increase site speed by 5% using React JS and Typescript
- Added E2E testing to improve trust of the project / code / deployments
- Added experimental features that lead to over $1,000,000 in annual revenue
- In order to alleviate the frustrations of legitimate customers who are having trouble logging in, we implemented a Bypass Login feature that lead to a $700k annual lift in orders.
- Created a guided sign up and login flow to guide users attempting to log in with unknown accounts and users attempting to sign up with known accounts down the right path. This lead to a 2.7% lift in user logins and signups.
