I'd look for places where React Native and Xamarin developers meet. There almost certainly are Slack communities for these technologies.
Such communities often have a dedicated #jobs channel. Seeing who is most active and who seems to be most knowledgeable about the specific areas of expertise you require can also be very helpful.
Don't wait for the good developers to apply, invite them proactively. 95% of the developers applying themselves are sadly the bottom barrel. First weed out from their profil history if they know what they are doing. Only work with people that have 100% Jobsuccess with relevant projects and have the "Top Rated" Badge. Then do a small test project with them or a free consultation call to check for details, how good their english is and cultural fit.
I have both hired myself and got hired on very successful projects (e.g. build an MVP for a startup in a month that led them to secure a funding round) this way. In case anyone wants to see my profile https://www.upwork.com/fl/tobiasheidingsfeld
Searching seems to be off at Upwork, for example, I'm look for someone add faceID support to a RN app and the results aren't too helpful. Looking at searches like "react native faceID" on upwork you would hope the top of the list would be the most relevant profiles containing all three terms or simply a search of "faceID" would return profiles containing this or biometric or react-native-touch-id, but searching the profile contents of the top five search results for this for me yield none of them having the search term. Testing google index against upwork is more effective for me 'site:upwork.com faceID'
I wouldn't add myself to any of the sites you mentioned. I don't want to be listed somewhere as an interchangeable commodity, don't want an intermediary getting in the way of payment and communications, and don't want to be somewhere that attracts clients looking for the cheapest option. I can't believe some of these platforms allow screen capture software that let clients spy on the contractor either.
There is an opportunity but as soon as you make the next upwork ... well you’ve made the next upwork! Make the next medium same thing. The gets shit as gets popular cycle repeats again and again.
My process:
1. OnlineJobs.ph/Dribbble/JobRack.eu/Local hiring website (exammple: Ejobs.ro)
2. Post a clear job ad with requirements/commitments/application form
3. Video call with the selected applicants
4. (Optional) Paid test task
5. Hired - Sign independent contractor agreement
I am a software engineer with 3 years of experience building web application in technologies like Php, Laravel, JavaScript, TypeScript, Reactjs, Nextjs, Nodejs, Expressjs and other tools. I have a very little experience as a freelancer (did some tasks on fiverr but didn't like that all). I am looking to work with clients on long-term basis. Are you looking for more freelancers to work with? If yes, I am interested. Looking forward to hearing from you. Thank you.
It's a chicken and egg problem. Most clients want to see previous work, but don't want their project to eventually become part of that previous work. The issue is compounded by the fact that most commercial software isn't flashy and easy to demonstrate to the casual observer like, say, a Dribbble account is for designers.
If experience with my own clients has taught me anything, it's that the best way to find good people is to just talk to them. Start incrementally - first a talk, then give them a few days worth or work, then a week, then more. Evaluate them at each step - starting with how they communicate and how professional they are and then the quality of their deliverables. I've noticed a pretty strong correlation between bad communicators and poor quality of work, thought YMMV.

Let me put it this way - there are two kinds of freelancers out there:
1. Those that invest in their visibility and charge for it. 2. Those that don't.
They might be equally good developers, but you're going to be paying a premium for the first one since he has intentionally made himself easier to find.
