I've been using Codementor for the last year or so and been very happy with them. For the past year I've worked for a US client and since a few weeks I work for an Australian client.
Why I like Codementor:
- The payments are done on time and they don't extract some platform fee as far as I know for the freelance jobs. Or it's invisible to me (perhaps more likely). What I ask per hour is what I get.
- There seems to be a decent amount of jobs available every month and not too many people respond to the same job as me at the same time. So there's a good chance that if I respond the job, I at least will be invited for a video call with the potential client.
- The rates on the platform seem decent (they advise setting somewhere between 40 - 80 USD, no race to the bottom imo). I'm based in Thailand, so these are rather nice rates for living here - I can save /a lot/ of money every month. My costs of living is currently around 1700 USD per month, everything above I can safe.
- I don't have to install software on my computer that spies on me to make sure I put in the proper amount of hours. And I actually tend to work more hours than I bill my clients, but I don't need software to keep me in check.
