I work on various projects that are under the KDE umbrella.
The Kate editor, a full-featured text editor
The KTextEditor framework, a versatile text editor component
The Syntax-Highlighting framework, > 300 languages supported
Random other stuff
Other KDE related contributions can be found on my invent.kde.org profile.
Contributors to these projects are welcome.
If you wish to sponsor the work done by KDE in non-technical ways, please think about donating.
