As someone looking for part-time Clojure work, I’d be interested for some tips and tricks as well 😄
FWIW I had no issues making offers to part-time applicants provided they matched category (a) of what I said above - i.e. one job that has your full attention but not within the traditional 40h week. Could be 5h/day (common for new parents) or 4 days a week etc.
The tricky bit is to convince businesses that you will feel like a “real” employee when it comes to communications. I’ve worked with freelancers in the past and they would “go dark”, have spotty availability for meetings, miss context etc which made it frustrating.
I think that even for remote work, it's important to learn how to leverage the asynchronous written communication, because be always actively aware on Slack or other chat channels can disrupt the focus needed to work with software. Basecamp (more known as 37signals) brings some tips about it on their Remote book.
