It is trivial that you should show some of your works in your job application/CV/website/reverse-job-application (does not matter for me how you call your pitch).
I think you can further improve this by:
- Providing the source code. You created something technically quite trivial (you have to deal with much more complex beasts even at an entry level job at BigCo), so the fact that you could do this is less interesting than how you solved this. Your coding style speaks a lot about your programming abilities.
- Or creating something technically less trivial (in that case the fact that you could do it is very interesting alone, so the source code is not that important). This may require more effort though.
