Front-End Developer | Accessible UI, TypeScript, component systems · Austin, Texas

Dear Hiring Manager,

I’m applying for the Front-End Developer role at your company. In my current position with a Retail Analytics Platform, I’ve built accessible React dashboards, improved keyboard navigation with ARIA, and refactored UI into a reusable component system to keep development consistent.

Previously, at a multi-location Healthcare Clinic Network, I developed patient portal screens in React and TypeScript. I aligned form validation with intake requirements, built responsive layouts for mobile use, and coordinated with clinical staff to reduce completion errors.

I’d bring a testing and quality mindset from my work at a large Industrial Equipment Manufacturer, where I integrated REST API data into UI views and added unit and integration tests to catch regressions early. I’m particularly interested in teams that prioritize accessibility, maintainability, and measurable performance improvements.

Sincerely
Amara Diallo

What hiring managers check first

Accessibility and UI quality

They check for evidence of ARIA, keyboard support, and semantic HTML in past UI work. They also look for clear outcomes like reduced errors or improved usability.

Modern front-end skills

They expect React and TypeScript listed with practical responsibilities. They also look for CSS layout experience such as Flexbox or CSS Grid.

Testing and reliability

They want to see unit or integration tests mentioned with what changed. They also check how testing reduced regressions during releases.

Performance improvements

They look for specific front-end performance actions like reducing bundle size. They also want a brief description of how the improvement was achieved.

Use the ones that are true of you, in the words the posting uses.

Mistakes to avoid

  1. Vague bullet points

    Applicants often describe responsibilities without stating what changed. Hiring managers look for the before/after impact of a delivered improvement.

  2. Overstuffed tool lists

    Including many unrelated technologies can make experience feel unfocused. Keep skills and tools tied to the work described in bullets.

  3. Cover letter mismatch

    Applicants sometimes repeat the resume instead of addressing posting requirements. A strong letter ties directly to accessibility, testing, and performance from the resume.

Questions

How long should a front-end developer resume be?
For 3 to 8 years of experience, aim for one page if possible, or two pages only if needed for clarity. Focus on recent, relevant projects and keep bullets outcome-focused.
What should go first on a resume?
Start with a short professional summary that matches the role, then list experience in reverse chronological order. Keep skills right after the summary so screening tools and reviewers can quickly verify fit.
What if I’m changing careers or have no direct front-end role experience?
Emphasize related UI work from any setting, such as building interfaces, fixing accessibility issues, or writing tests. Add a brief skills section and education projects that demonstrate React, TypeScript, and testing.
