Frontend Developer Intern resume writing tips
- Quantify project impact using browser performance metrics like Lighthouse scores or bundle size reductions.
- Highlight experience with collaborative tools like Git to show you can work within an engineering team.
- Showcase a design system or component library project to prove you understand UI consistency and reusability.
Common mistakes
- Listing every course ever taken instead of focusing on the 3-4 most relevant ones like Data Structures or Web Development.
- Describing project tasks ("I wrote code") instead of outcomes ("I built a dashboard that fetches real-time REST API data").
- Neglecting to mention soft skills like code reviews or collaboration which are vital for interns joining established teams.
Frequently asked questions
Is this resume right for someone with zero internships? Yes, if you showcase personal projects or open-source work that proves technical depth beyond basic classroom assignments.
Yes, if you showcase personal projects or open-source work that proves technical depth beyond basic classroom assignments.
Yes, if you have significant personal projects or open-source contributions that demonstrate technical depth. No, if your experience is limited strictly to introductory classroom assignments without any independent application.
What if I am a self-taught developer without a CS degree? Yes, focus on a projects-first layout featuring live portfolio links and GitHub repos to prove your skills match formal education standards.
Yes, focus on a projects-first layout featuring live portfolio links and GitHub repos to prove your skills match formal education standards.
You should replace the education-first layout with a projects-first approach. Focus on showcasing your GitHub repository or a live portfolio link to prove your skills are equivalent to a formal degree.
What if I don't have access to production metrics like bundle size? Use Lighthouse scores or bundle size data from personal projects to demonstrate your awareness of performance and optimization standards.
Use Lighthouse scores or bundle size data from personal projects to demonstrate your awareness of performance and optimization standards.
In this resume, Jennifer uses Lighthouse scores, which you can also generate for your own projects. Reporting a 1.1s page load time for a personal project is a valid way to demonstrate performance awareness.
How much should I change before applying? Retain the core structure but swap specific technologies to match the job description, ensuring project details reflect their specific tech stack.
Retain the core structure but swap specific technologies to match the job description, ensuring project details reflect their specific tech stack.
Keep the structure of the skills and experience bullets, but update the specific technologies to match the job description. If a company uses Vue instead of React, ensure your project descriptions reflect your ability to adapt to that stack.
What do hiring managers focus on at this level? Managers seek signal that you can navigate modern workflows like Jest or Storybook to contribute to a codebase with minimal hand-holding.
Managers seek signal that you can navigate modern workflows like Jest or Storybook to contribute to a codebase with minimal hand-holding.
Recruiters look for signal that you can contribute to a codebase with minimal hand-holding. Demonstrating familiarity with modern workflows—like using Jest for testing or Storybook for components—signals that you are ready for a professional environment.
