Dear Hiring Manager,
I am excited to apply for the React Developer position at Brightwave Interactive. With 5+ years of experience building accessible, performant interfaces with React and TypeScript, I am interested in helping your team ship polished products that feel fast for every user. Throughout my career I have focused on writing reusable components with hooks and clean state management that stay easy to maintain as products grow.
In my current role at Hearthside Media, I build and maintain React applications, manage state with Context and Redux Toolkit, and improve performance through code splitting and memoization. Recently I led a refactor of our reporting dashboard that improved Largest Contentful Paint from 3.4s to 1.8s and raised our Lighthouse accessibility score to 98, which made the app noticeably faster and more usable. I work closely with designers to deliver pixel-accurate, accessible UI and keep components well covered with Jest and React Testing Library.
What interests me about Brightwave Interactive is the opportunity to work on products where interface quality, accessibility, and Core Web Vitals directly shape the user experience. I would be glad to contribute my experience with React, TypeScript, hooks, state management, and testing to help your team ship features with confidence. I enjoy work where careful frontend decisions make the whole product feel faster and easier to use.
Sincerely,
Liam O’Connor
