Web Developer Cover Letter Example
Web developer letters fail in a predictable way: they list technologies without evidence. Hiring managers assume anyone can type a framework name into a skills list, so the letter's job is to attach each claim to something that shipped, with a number attached (load time, conversion, traffic, error rate) and ideally a URL they can open.
Use the example below as scaffolding and replace the projects with yours, consistent with your web developer resume example.
The example letter
Dear Ms. Iwamoto,
I'm applying for the Web Developer position at Brightwater Studio. For the past three years I've built marketing sites and e-commerce fronts at a 12-person agency, most recently rebuilding a specialty retailer's storefront in Next.js and Shopify's Storefront API. That rebuild took Largest Contentful Paint from 4.1s to 1.6s on mobile and lifted checkout conversion 14% quarter over quarter.
Your posting lists React, TypeScript, and headless CMS work, which is my daily stack: I've shipped eight production sites on Sanity and Contentful, write TypeScript strictly enough that two of our juniors use my configs, and hold every site I ship to WCAG 2.1 AA, verified with axe and a screen reader rather than a badge widget.
Agency pace is the part of this job I actually like. I've run three client launches in a single month, handled the DNS cutovers myself, and kept a post-launch defect list short enough to fit in one standup.
My portfolio with live links and case notes is at the URL on my resume. I'd welcome the chance to walk through the storefront rebuild in detail. Thank you for your consideration.
Best regards,
Theo Vandenberg
Writing tips for Web Developer cover letters
- Anchor paragraph one to a single shipped project with a performance or business number. "LCP from 4.1s to 1.6s" outweighs a paragraph of framework names.
- Match the posting's stack exactly and honestly, and skip technologies you'd need to relearn; a precise 80% match reads stronger than a vague 100% one.
- Treat accessibility as a differentiator: name the standard (WCAG 2.1 AA) and how you verify it. Few applicants do, and many clients now require it contractually.
- Reference your portfolio and make sure every link opens: managers do click, and a dead link in a web developer's application is a self-review.
- Show comfort with the employer's delivery context (agency launch pace, in-house product cycles, or freelance handoffs). The work rhythm differs more than the code does.
