Priya Raman
Senior Frontend Developer, Digital Banking, Woodgrove Bank
Dear Priya Raman,
I'm applying for the Senior Frontend Developer role on Woodgrove Bank's digital banking team. At Northstar Ledger I build customer-facing features in React and TypeScript for a budgeting app used by 400,000 people a month, and your posting's focus on fast, accessible account pages is exactly the work I've been doing.
The project I'd point to first is our move to Next.js. I moved the marketing site and account pages to server rendering, and mobile Largest Contentful Paint fell from 4.1s to 1.8s. Around the same time I led an accessibility pass against WCAG 2.1 AA and fixed 120+ issues found with axe and screen reader testing in NVDA and VoiceOver — the kind of work a bank can't treat as optional.
I also try to make the next feature easier to build. I built a shared component library in Storybook that 4 product teams now use, with Playwright end-to-end tests on every pull request. Before Northstar, at Pixelworth Studio, I built 15+ responsive client sites and raised unit test coverage on a checkout widget from 35% to 80% with Jest and React Testing Library.
I'd welcome the chance to talk about Woodgrove Bank's plans for its web app and where I could help. I'm available for a call most afternoons next week.
Sincerely,
Leah Brennan

/ Tips
Tips for your frontend developer cover letter.
01
Lead with one measurable improvement
A load-time, accessibility or bug result with a before-and-after says more than a list of frameworks.
02
Match their product
If the company is a bank, a store or a media site, pick the result from your resume closest to what their users do.
03
Mention how you help other developers
Component libraries, tests and code review show you think beyond your own tickets.

/ Questions
Cover letter FAQ.
Something else? support@launch-cv.com
Do frontend developers need a cover letter?
It's often optional, but a short letter helps when you're changing industries, applying to a smaller team or writing to a hiring manager directly.
Should I link my GitHub in the letter?
Only to something relevant, like a component library or a project close to their product. Link the specific repository, not just your profile.
