What about a few small contributions to open source?

[reposting an old comment]

Which open source projects are you using and you like? Try to contribute to them.

Start sending bug reports that are very useful and sometimes underestimated. Look how/where they fix them and the next time try to send a pull request (or another bug report).

Fixing typos in docs is also a good starting point.

If you want to send a new feature, start with something small, like a weekend project. You never know if the maintainer will like it, or if they are morons or if they have very weird code rules.
