Have you manage to do freelance jobs (remote or not) while slow travelling? What resources did you use?

It seems that there is big platform as Freelancer[1] or Upwork[2] and some specifics one as Working Nomads[3].

My story: Made the decision to quit my job and travel the world for a while. One-way ticket to India, next stop Nepal. After 3 or 4 months I think I'll stay in a place for like a month or so and work as freelance or on my side projects for some times.
