I quit my job and became self-employed ~6 months ago. I work as a freelance developer and I focus on 3D graphics and computer-vision, but I occasionally take on other projects if they are interesting.

I find jobs on Upwork and I do cold reach out on LinkedIn and via email. So far, I managed to keep myself pretty busy and I landed a few pretty good projects. I consider that a success since I went into the freelancing world not knowing much about it.

It's hard, especially with the uncertainty of where the next project/money is coming from, but I can't imagine going back to a full-time employment anytime soon.
