A frontend developer's portfolio should let the reviewer see and try the work. For each project, explain the problem, the technical decisions you made and what improved, then link a live demo and the code. The resume lists your stack; the portfolio proves what you built with it.
For: Frontend developers who want to present projects with live demos, code and measurable performance gains
Give every project a working demo link and, where possible, a public repository. Reviewers often open the demo before reading anything else, so make sure it loads quickly and works on a phone. If the code is private, include a short architecture diagram or a few key snippets instead. Check every link in a private browser window before sending.
Describe why you chose a framework, state management approach, rendering strategy or library, and what you traded off. One or two decisions per project, each with a short reason, show more engineering judgment than a list of technologies. A simple diagram of the component structure or data flow works well. Caption it so it can be understood without the code.
Frontend results can be measured: load time, Core Web Vitals, bundle size, error rate, accessibility score or conversion after a speed fix. Give the before and after values and the tool you used to measure them. State the team size and which parts you owned, such as the design system or the checkout page. Numbers like these turn a demo into evidence.
BeforeBuilt a shopping website using React and Next.js.
AfterRebuilt the product listing page in Next.js with server rendering, cutting largest contentful paint from 4.2 s to 1.8 s on mobile.
The stack becomes meaningful once it is tied to a decision and a measured outcome.
BeforeMade reusable components for the team.
AfterBuilt 32 accessible components in a shared library used by 3 product teams, reducing duplicated UI code by about 40%.
Scale, adoption and the code saved show the impact of the work beyond your own tickets.
BeforeFixed bugs and improved the site's stability.
AfterAdded error tracking and 120 component tests, lowering front-end errors per 1,000 sessions from 14 to 3.
A named practice and a before-and-after rate show that stability improved because of specific actions.
A GitHub profile shows code, but not the problem, your decisions or the result. A short portfolio of two or three projects that links to the repositories gives the reviewer context and saves them from reading code blind. Pin the same projects on your profile.
Describe the problem, your approach and the results without internal names or code, and use ratios for confidential numbers. Rebuild a small, public version of a key technique if you can, and link that instead.
Yes, especially if they solve a real problem and have real users or a live deployment. Treat them like work projects: state the problem, the decisions and at least one measured result, such as load time or number of users.
The button opens a portfolio filled with this example in the editor. You need to sign in; change the text, images and layout of every slide freely and download it as PDF or PPTX. Drop your own work onto the image spots.
