How to find and choose a programmer for a mobile application? What to pay attention to? How best to collaborate?

Answer 1

View portfolio of completed projects.
Chat, see if the person is adequate, how he constructs a speech.
How many years, how many years working in the industry.
Universal advice: agree to pay in installments, for example: 10% + 30% + 30% + 30%
Pay 10% upfront, wait for the first results
if (you like everything) => pay further
if (no) => 10% is not a big loss .
For your small 10% advance, you will understand whether you are comfortable working and whether you see a long-term perspective with this person. Because the application will be made, say, for half a year, and then it will need to be regularly updated and supported. And to change a programmer at the crossing is the same as that half of the picture was painted by one artist, and then another was called (God forbid it turns out to be some kind of avant-garde artist). Business impact. A new programmer will work worse with someone else's code, because he will not see all the ideas of the author (most likely).
If you are serious about business and you don’t feel sorry for 500-1000 dollars for the right thing, you can pay several candidates at the same time. In fact, give a test task. And choose the one you like best.
