Pages using CMS or whatever need, it depends on a project.
I often contribute to the open source community.
And I've translated many projects and even mobile applications into Slovak (Czech too) as well.
Some of the open source projects I've worked on:
A web dashboard for your favorite caching system.
Create a unique avatar for each user based on their name.
A toolkit for developing universal web interfaces with support for multiple CSS frameworks.
Simple but powerful Markdown documentation.
Simple cache for PHP with support for Redis, Memcached, APCu and Files.
A theme for the elFinder web file manager inspired by Google Material design.
