Ask HN: Where do seasoned devs look for short-term work?

In a short form question: If you do, where do you look for a short time projects?

I'd like to put my skill set to use and work on a project, I'm available for 6-9 months. The problem seems to be for me, that I cannot find any way of finding such project.

I'm quite skilled, I have 15 years of experience, first 3 as a system administrator, then I went full on developer - have been full stack for 2 of those years, then switched my focus fully on the backend - and ended up as platform data engineer - optimizing the heck out of systems to be able to process data fast and reliably at larger scale.

I already went through UpWork, Toptal and such and to my disappointment, there was no success to be found.

Do you know of any project boards, or feature bounty platforms, that I could use to find a short time project?

Thank you for your wisdom :)
