A frontend portfolio that explains how you think.

Choose a task that someone can complete

A frontend portfolio becomes more useful when its central task is obvious. Choose a small problem such as organising study sessions, browsing a resource library or tracking applications. Write a short scenario describing who uses it and what they should achieve. Build that journey before adding more pages or visual effects.

A coherent project gives you room to discuss trade-offs. Explain why you chose a component boundary, how state changes and which information is stored. If the project uses sample data, label it as a demonstration. Do not present fictional customers, invented usage numbers or mocked external services as real outcomes.

Make the less glamorous states work

Design what the person sees before data arrives, when there is nothing to show and when a request fails. Add a retry path that does not erase completed work. Check a long title, missing image and small screen. These details help a reviewer understand whether you considered the whole interaction.

Use semantic controls and clear labels. Navigate the main task with a keyboard and verify that focus remains visible. Make form errors specific enough to correct. Read the page at increased zoom and test the layout without assuming a large desktop monitor. Record what you tested and what still needs review.

Use React and TypeScript to clarify the behaviour

React’s official learning material covers components, state and event handling. Use those ideas to keep the interface understandable. Give each part a clear responsibility and avoid adding a library merely to make the technology list longer. A simple implementation that you can explain creates a better discussion than an elaborate one you cannot maintain.

Use TypeScript to describe the data your UI actually handles. Distinguish a loading result from a successful result and a failure. Avoid making every field optional just to silence the compiler. When a server response needs validation, treat a compile-time type as separate from checking data received at runtime.

• Show one important interaction with a meaningful test.
• Keep configuration and private keys outside client code.
• Explain a constraint you deliberately left out of scope.

Present the work as a small case study

A useful README explains the problem, setup, design choices and known limits. Add a short walkthrough of the main user journey and include clear screenshots if they help. Keep the live demo and repository links easy to find. Check both links before sending an application rather than assuming yesterday’s deployment still works.

Prepare one story about a bug and one about a product decision. What did you observe, what did you change and how did you check the outcome? These stories connect your code to practical reasoning. Add the project to your résumé with an accurate statement of your contribution and the behaviours you implemented.
