Hi, I'm Skyler!

I'm a 19-year-old software engineer, I love writing libre code for software I use.

I've been using LibreOffice for years, so I was excited when I got a job at Collabora Productivity, which gave me an excellent path to contribute! I've worked on various features, including STYLEREF, a WebSocket-based URP Connection, and miscellaneous LibreOffice Kit changes.

In my free time, I like writing software - I'm currently interested in infrastructure and build systems, particularly with Nix; moderating online communities, and offline activities such as reading.

After first working for Sun Microsystems on then-OpenOffice.org, he then went with a number of others founding The Document Foundation and the LibreOffice project.

These days, his day job includes substantial amounts of project management and customer interactions, which does not prevent him from still messing with LibreOffice code. He's recently spun up his own company allotropia to have even more fun with open source all day!
