Anyone bootstrapped his way to freedom while doing a full time job?

I’m working a full-time job as a product manager, and building a job board in parallel. No revenue yet.

My goal is to indiehack my way to freedom.

Anyone else indiehacked his way to freedom while working full-time?
What are your learnings, what worked, what didn’t?
How long did it take you?
How did you get any sales done?
…

Thanks !
