My concern is can you make it worth my time? Do people hire staff/architect level devs on a freelance basis? I don't want to compete with developers in developing countries.
I don't now but I tried in the past. Working with individual clients is worse than my day job, so I want to make more per hour, not less. I don't think it can be worthwhile, unless I find myself REALLY needing the money (i.e. unexpected debilitating medical bills).
I use my free time for music and family (not in that order)
