I like to have both, at least for now. I work for a Fortune 500, and do interesting projects, slowly, every line of code has a purpose. There is a lot of compliance around security and data privacy, unlimited AWS spend and limited creativity.

Side-projects are fast-paced, with a lot more creativity and entropy involved. I'm sure having experience in both make me a better maker.

So far people in corporate have been supportive of my side hustle, so I do not separate both on social media.

Email password for me, with a password manager it's convenient, and I don't mix everything in a single Google account.
