Choose a useful problem, finish a small project and present your contribution clearly.

Choose a problem you can finish

A useful first project solves one clear problem for a specific user. Examples include a college event organiser, a personal budget dashboard or a recruitment tracker. Keep the first version small enough to complete and test.

Define the scope

Write who the user is, what task they need to complete and how you will recognise success. List three essential features and put optional features in a later-work section.

Design the data and flow

Sketch the main screens and the information each needs. Decide which fields are required and what should happen when data is missing. For an analytics project, document the dataset, column meanings and cleaning decisions.

Build incrementally

Finish one usable flow before adding another. Save progress in Git, check your work and write down important decisions. Ask a friend to try the project without your explanation.

Handle the difficult cases

Test failed requests, duplicate submissions, long text, empty lists and mobile layouts where applicable. Never use real sensitive information in a public demonstration.

Present your contribution

Write a README with the problem, approach, setup, screenshots and limitations. Describe what you built yourself and which libraries or resources helped. Explain one bug you fixed and one trade-off you made.

Suggested completion criteria

1. A working core user flow or reproducible analysis.
2. Clear setup instructions and sample data.
3. Evidence of meaningful checks.
4. A short demonstration and honest limitations.

Use feedback for the next version

Collect specific observations rather than asking whether the project looks good. Improve the most important usability issue first. A completed, understandable project is a stronger learning outcome than an ambitious unfinished one.
