While initially hired as the sole developer in the company's website, I took initiative to contribute to their main products. Here's a quick list of my impact across their whole tech stack.

Improved the Largest Contentful Paint (LCP) across all pages of the app by up to 50% in Lighthouse by resolving an issue with eager loading and optimizing the image file sizes through .webp conversion

Optimized the load time of the app's search results in the app by up to 10% by identifying and refactoring compute-heavy redundant operations

Created a passwordless authentication flow to automatically log in users with a link alone using AWS Cognito

Maintains at least 60% unit test coverage in new code across all contributions in the app and API

Implemented email notifications through AWS SES and in-app notifications through GraphQL on flight updates

Created an admin feature to modify the app's configuration in multiple development environments in realtime
