Ask HN: LinkedIn Profile for a Side Project While Working Full-Time at a Company

I have been working full-time at a media/gaming company. I also have a side project that I'm working on. To bring more users to my side project, I need to create LinkedIn posts to target my potential customers. The problem is, I want to hide this from my company and its employees.

What should I do?

Create a new LinkedIn profile with my real name but an AI-generated photo.

Create a new LinkedIn profile with completely fake identification. This may harm my project if someone finds out.

Or do you have any other recommendations?
