Dear Ms. Mercer,

A storefront that loads in 1.6 seconds isn't a vanity metric — it's revenue. When I rebuilt Brightline Commerce's storefront in Next.js and TypeScript, mobile Lighthouse performance climbed from 58 to 96 and Largest Contentful Paint dropped from 4.1s to 1.6s. That kind of front-end work — fast, accessible, measurable — is exactly what drew me to the Senior Web Developer role on Tidewater Labs' Web Platform team.

I care about the numbers users feel. At Brightline I led a checkout redesign that lifted conversion 18% and cut cart abandonment 11% by making the flow faster and more accessible, and I built a 60+ component design system in Storybook that four squads adopted, trimming new-feature build time by roughly 40%. Earlier, at Northpeak Media, I shipped 30+ React features for a platform serving 2M monthly visitors while holding every Core Web Vital in the green, and migrated a legacy jQuery UI to Vue 3 — shedding 1.2 MB of page weight.

Accessibility is the part I won't compromise on. I drove WCAG 2.1 AA compliance to 100% of audited pages, resolving 140+ issues and adding keyboard and screen-reader coverage, and I hold the IAAP Web Accessibility Specialist certification to keep that rigor honest. Paired with a testing discipline that raised front-end coverage from 22% to 81% using Jest, React Testing Library, and Playwright, it means the UI I ship stays fast and correct long after launch.

I'd welcome the chance to talk about how I can help Tidewater Labs ship interfaces that are quick, inclusive, and built to scale. My resume is enclosed, and you can see shipped work and source at ethanpark.dev and github.com/ethanpark whenever it's useful. Thank you for your consideration.
