Scorpion
https://www.scorpion.coAn Angular enterprise application that hosts a suite of marketing tools for business clients. I was a front-end engineer on the shared team in charge of building foundational UI modules utilized by developers on other teams. For each component, I regularly wrote E2E tests in Cypress.io and unit tests in Jest. I also documented the usage of modules with Storybooks. That job was UI-focused, so advanced styling concepts such as mixins and variables in Sass and Angular animations were implemented extensively.
Cerebro Web Application at Everyday Labs
https://www.everydaylabs.com/A React-based edtech web application that delivers dashboards for school district managers to monitor key metrics of schools. I was the senior React engineer in charge of architecting and building the platform from scratch. I used functional components, Tailwind CSS, and hooks to build the UI of the application. GraphQL was incorporated to communicate with the API, and I also added storybooks for documentation and Cypress.io for E2E tests.
NFT App on the Solana Blockchain
Built an application that allows users with NFTs in their wallets to interact with other users on a social messaging platform. NFTs in wallets can be seen by any user who is a friend, NFT activity is fetched in real-time for each wallet to observe, and NFTs can be shared in messages with animations.
