Marcus Ellery
Front End Developer, React and TypeScript
Denver, COmarcus.ellery@example.com(303) 555-0161Summary
Front end developer with six years of experience building product interfaces in React and TypeScript for a B2B scheduling platform. Led the move to a shared component library now used by four product teams, and cut the main bundle by 40 percent without dropping a feature. Works closely with designers and treats accessibility as part of done, not a later ticket.
Experience
Front End Developer, Timberline Scheduling
– Present
Denver, CO
- Built and documented a component library of 70 React components in Storybook, adopted by four teams and cutting duplicate UI code across the app.
- Reduced the main JavaScript bundle from 1.2 MB to 720 KB through code splitting and dependency cleanup, improving first load on slow connections.
- Rebuilt the booking flow with the design team; completed bookings rose in the two months after release.
- Brought the app to WCAG 2.1 AA on its five most-used screens and added automated checks so regressions fail the build.
