Engineering Manager

Yatrikund Travels

Subject: Application for Front-End Developer

Dear Mr Kulkarni,

On a mid-range phone over 4G, checkout at Thaliport Commerce now loads in 1.8 seconds instead of 4.1, after I rebuilt image loading and code splitting. I want to do that kind of measured speed work next as a Front-End Developer at Yatrikund Travels.

I build and maintain that checkout in React and TypeScript for about 90,000 shoppers a month. When an accessibility audit found keyboard and screen reader problems across 14 screens, I fixed them and tested with NVDA and TalkBack, then built a small accessible form kit that three teams now use. I also rebuilt our payment step with clear retry and pending states for UPI apps, so shoppers stopped paying twice. Component tests I wrote raised coverage from 38% to 72%, which keeps those gains in place when others change the code.

Yatrikund rebuilding its booking site is why I am applying now. A rebuild is the moment speed and accessibility can be designed in rather than patched, and most of your bookers are on phones, as most of our shoppers are. Pilgrimage travelers also include many older people, which is the reason I earned the IAAP Web Accessibility Specialist certification. To review code and mentor junior developers, I already take about 15 pull requests a week and mentor two juniors, and at Sabarwave Digital I introduced a shared component library that every new project used, which is how a small team keeps a rebuild consistent.

Send me the slowest page on your current booking site, and a short profiling write-up of it will come with me to the interview, done the way I approached our checkout. My own question is how you plan to test the new booking flow with screen reader users before launch.

Warm regards,

Kinjal Solanki

A made-up letter. The person, the employers and every number are invented, and any resemblance to a real one is chance. Sending it by email? Put the subject line in the email’s subject box, add your name to it, and attach the letter as a PDF.

Paragraph by paragraph

  1. The opening

    Starts: “On a mid-range phone over 4G, checkout…”

    Names the device, the employer and the result in the first line, so the reader knows the figure was measured where real users are.

  2. Your strongest evidence

    Starts: “I build and maintain that checkout in…”

    Answers the advert's stack, speed and accessibility lines, and shows the gains are protected by tests.

  3. Why this employer

    Starts: “Yatrikund rebuilding its booking site is why…”

    Gives a reason tied to the employer's rebuild and its bookers, and answers the review and mentoring line in the advert's own words.

  4. The close

    Starts: “Send me the slowest page on your…”

    Turns the close into a small work sample built on the employer's own site, which a hiring manager can judge.

Why this letter works

  • The speed figure names the phone and network it was measured on, which matches an employer whose bookers mostly use phones.
  • Speed, accessibility and test coverage each come with a before and after or a scope.
  • The reason for applying is the employer's rebuild and its travelers, linked to the writer's own certification.
  • The close offers to profile the employer's own page, a work sample rather than a request.

How to write your own front-end developer cover letter

  1. Give load time in seconds before and after, and say which phone and network you measured on.
  2. Describe accessibility work by what you fixed, on how many screens, and which screen readers you tested with.
  3. Show that your gains last: mention tests or shared components that keep them in place.
  4. If the employer's customers include older users, say what that means for the screens you would build.
  5. Offer to profile one of the employer's own pages as a short work sample.

Common questions

Should a front-end developer include a portfolio link in the letter?

If you have public work, yes, near the end as one link. Checkout and account work is often private, so a written profile of a public page can stand in.

Does an accessibility certificate matter to front-end hiring managers?

It helps when backed by fixes you have shipped. Mention the certificate once and spend more words on the screens you made usable.

How do I talk about payment screens in a front-end letter?

Say what went wrong for users before, such as double payments or unclear pending states, and what you changed. Leave out payment provider names unless the advert uses them.
