Hi,
I’ve been in a similar situation. Two important things to keep in mind: first, separate your work from personal projects. Definitely don’t share your employer’s intellectual property.
Second, and more importantly, be clear about why you want to share your work with the community. I thought about this a lot and realized it matters more to me that my work is useful, helps, or inspires others, rather than keeping things as “black boxes” and hoping to profit someday.
For me, the main goal of side projects is to learn something new. If they help someone, great. If not, they still served their purpose: I learned something new.
So if your goal is to learn, help, or inspire, go for open source. You don’t have to share everything—that’s up to you.
That’s just my perspective on open source and evening side projects. You might find a different (maybe better) path. Hope this was at least a bit inspiring 🙂
