Subject: Frontend Developer Application — [Your Name] | React + TypeScript
Dear [Hiring Manager],
I'm applying for the Frontend Developer position at [Company]. With 5 years of experience building high-performance web applications used by millions, I'm excited about the opportunity to contribute to [Company]'s mission to [specific goal from job posting].
At [Current Company], I led the frontend rebuild of our e-commerce checkout flow using React and TypeScript. By implementing code-splitting, optimizing bundle size, and improving Core Web Vitals (LCP improved from 4.2s to 1.8s), we increased checkout completion rate by 18%—translating to $2.3M in additional annual revenue.
Beyond performance, I care deeply about accessibility. I championed WCAG 2.1 AA compliance across our product, personally auditing and fixing 200+ accessibility issues. This expanded our addressable market and, more importantly, made our product usable for everyone.
I admire [Company]'s attention to design quality and user experience. I'd love to bring my expertise in [specific technology] to help build [specific feature or improve specific metric].
Best regards, [Your Name] [Portfolio] | [GitHub]

| Mistake | Why It Fails | Fix |
|---|---|---|
| Framework listing only | "I know React" is table stakes | "Built React app serving 500K MAU with 99.9% uptime" |
| Ignoring business metrics | Pretty UIs don't matter if they don't convert | Connect your work to user metrics, revenue, engagement |
| No portfolio/GitHub | Frontend is visual—show your work | Always include links to projects you can demonstrate |
| Only technical focus | Frontend is user-facing | Mention UX collaboration, user research, accessibility |
