Dear Hiring Manager,

Your Web Developer opening caught my attention because of the product itself: I have used it, and I can see the engineering choices behind it. I have spent four years in marketing sites and web apps for agency clients, and I would like to bring that experience to Brightline Software.

Most recently, I rebuilt a client's site in Next.js, lifting Lighthouse performance from 41 to 96 and organic sign-ups by 23%. I write accessible, semantic front-ends and am comfortable with REST APIs and headless CMSs.

Your posting asks for JavaScript, React and HTML/CSS, which is the part of the work I do best, and I would bring the same care to accessibility and performance. I want to build fast, accessible websites for your clients, and I would welcome the chance to talk about how my experience fits your plans for the team.

Thank you for your time and consideration.

Sincerely,
Alex Morgan

Why this web developer cover letter works

The opening gives a reason. It names the role and says why this employer, instead of "I am writing to apply".
One result carries the middle. A specific, measurable achievement does more than a list of duties.
It reuses the posting's words. Skills like JavaScript, React, HTML/CSS appear the way an employer would write them, which helps both applicant tracking systems and a skimming recruiter.
It ends with a next step, politely, in two lines.

What technology employers look for

Name your stack precisely, link to a portfolio or GitHub if relevant, and quantify impact (latency, uptime, users, revenue) instead of listing technologies.

The company name, the candidate and the numbers in this example are illustrative. Replace them with your own.
