This is Kai Torben Ohlhus (a.k.a. siko1056 on Discourse and alike). I started contributing to GNU Octave during GSoC 2013 as student and worked on incomplete factorizations (read my blog). The project was completed in GSoC 2014 by Eduardo.
Since 2013, I continuously support the development of "core" Octave and maintain parts of the Octave Project Infrastructure:
- Several code contributions to GNU Octave itself.
- Triage the bug tracker (review, comment, and push patches).
- Support the release process (create and upload [interpreter] and Doxygen documentation).
- Co-maintainer and caring for updates of
- this Octave wiki (all contributions).
- the official GNU Octave website https://www.octave.org (page source).
- the Octave Discourse forum.
- several Octave packages.
- GSoC mentor in 2014, 2018, and 2020-2022, co-mentor in 2017.
