Begin with a user journey
Choose a feature someone could complete end to end. What did they need to do, what prevented them, and what happened when something failed? An engineer's account can then connect interface state, accessibility, API behavior and persistence to that need.
For a React interface, describe loading, empty, success and error states rather than only the happy path. Explain how keyboard users and smaller screens could complete the same task. Visual polish matters, but so does not losing a user's work when a request fails.
- Identify what state lived in the browser and what the server owned.
- Explain one accessibility or responsive choice.
- Describe how you verified a completed action after navigation or reload.
Treat the API as part of the product
Node.js can serve many architectures; the practical questions are who may call an endpoint, what input it accepts, what output clients can rely on and how errors appear. TypeScript can clarify a contract, but a type definition alone does not enforce authorization or validate untrusted input.
When you describe an integration, make clear whether you built the service, used a third-party API or worked within an existing platform. That distinction is not a weakness. It lets another engineer understand the part you owned and the failure modes you had to manage.
- Give an example of a rejected or incomplete request.
- Explain where user identity or ownership is checked.
- Describe how client and server agree on data shape without exposing production records.
Show decisions across the life of a feature
A maintained product changes after release. Tests, monitoring and user feedback may reveal a design gap. Explain a trade-off you made, what evidence changed your mind and how you improved the implementation without breaking existing workflows.
Collaboration is part of the story. Product and design colleagues may define the need, QA may expose an edge case and operations may see a production failure. State your decisions clearly without claiming every outcome as your own.
Explain your project in a stronger professional profile
Use a concise structure: the user problem; your responsibilities; key React, Node.js or TypeScript choices; one difficult edge case; and how the team checked the result. A non-confidential architecture sketch or interface example can add evidence if it is yours to share.
Refresh the entry when the work matures. A prototype, a launched feature and a service you operated for a long period show different strengths. Employers can ask better questions when those stages are not collapsed into a single tool list.
