Which freelance platform to choose for the front?

Question

Freelance

Good afternoon.

• What platforms should a novice developer pay attention to? The task is to find the first clients, to make at least a couple of commercial projects for the portfolio.
  
• What are the pros, cons, pitfalls?
  
• Which projects should be taken, and which ones should be abandoned, if you are interested in react, redux, but there is no certainty in their use yet. Is it possible to learn from commercial projects, or is it better to build landing pages first?
  
• And there is also the issue of deadlines. How to decide on them if there are only 3 training projects? How to negotiate deadlines with clients?
  

Answer 1

If you plan to build a "career" of a freelancer, then immediately go to upwork and do not spray reviews on different exchanges.

Answer 2

Do not go to the upwork beam right away, work a little on the Russians for a start
