Professional Experience

Software Engineer Cinder2023 - Present

Cinder is dedicated to making the internet safer through advanced Trust and Safety software.

As the sole frontend engineer, I spearheaded the complete redesign of Cinder’s frontend, aligning it with future-ready architectural patterns and improving scalability for evolving Trust and Safety challenges. By implementing Bolt, our new design system, I streamlined our component library and introduced robust design tokens for consistent theming. This overhaul has simplified the development process, minimized potential errors, and enabled faster feature rollouts, empowering our team to build solutions that keep pace with the shifting digital landscape.

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.
