Dear Hiring Manager,
After several years in an adjacent role, I am moving deliberately into frontend engineer work because the strongest part of my recent job has been component architecture, browser performance, testing, and close design partnership. Over the last year I have built hands-on evidence with React, TypeScript, Next.js, Playwright, Storybook, and WCAG AA patterns, so this is a planned move rather than a loose interest.
I am not asking you to infer the connection between my old title and this role. Your team needs accessible interfaces, performance work, design-system discipline, and release confidence, and my strongest examples sit in that exact area. I would use this letter to show the connection with one specific project, the constraints I worked under, and the judgement I brought to the decision points.
A recent example is that I rebuilt a customer onboarding flow, removed 31% of client JavaScript, and improved LCP from 3.2 seconds to 1.9 seconds. That work required React, TypeScript, Next.js, Playwright, Storybook, and WCAG AA patterns, but the more important point is how I made decisions, explained tradeoffs, and followed the result through after release.
I would welcome the chance to talk through how this transition maps to your team needs. frontend hiring managers look for product polish as well as JavaScript depth, so I would keep the letter concise, evidence-led, and tied to the outcomes the hiring team is likely to care about.
Yours sincerely, Alex Morgan
