A small finished project is the best proof of skill. Pick a real problem, find data, build a simple baseline, then improve it. Measure on test data you kept apart and study the mistakes. Write an honest README. Then turn the project into short stories for interviews.
- Baseline
- The simplest method that could work, used for comparison.
- README
- A page that explains a project and how to run it.
- Portfolio
- A collection of projects that show your skills.
