I'm paid to do a mix of open and closed source coding. Rather, I manage a team who do, and I still code because I'm a stubborn bastard.

I've been at this for decades, and had to carefully and willfully craft a space to open-source work from my team that makes sense to share.

I did a lot of closed source coding on the way to this point in my career.

At the end of the day, my open source commits will outlive me, but my closed source commits put food on the table.
