I saw that you are looking for help with building Open Office from source and I think my current set of skills could be put to good use with this task.
I have been working as Build admin/DevOps for the past 7 years, mostly on Windows envs but recently (about 1 year now) I have switched to Linux. During this period I have worked on tools and scripts used to automate the build process and also by developers in their day to day job. Some of the languages I’ve worked with are C++, C#, a bit of Python and a bit of Perl. I have written scripts mostly in batch (as I said, most of my experience was acquired on Windows envs) but now I started working more in bash. When it comes to VCS, I have worked mostly with Mercurial and Gitlab, but I am also familiar with SVN and CVS (from way back in the days).
I like working on automation and have a keen eye for spotting patterns and doing detective work. I am not a developer when it comes to writing complex code, but even so, given a task, I don’t ever back away from the challenge.
If you are interested in collaborating let me know and we can discuss more.
