How to find a developer for a team if you don't know the technology?

Question

Work organization

Hello. The developer himself, but in terms of the backend, you need to find a developer to develop a mobile application on flutter, but here's the problem, I don't know either dart or the flutter framework, so I won't be able to conduct an interview, as well as difficulties in understanding the quality of the code and correct time estimates .

What are the possible solutions in such a situation?
You can, of course, yourself, at least understand the basics, but this is the time and in any case experience is needed

Answer 1

Resume, see the list of jobs, see the list of previous jobs, experience in specific technologies. How much he worked on the stack, what he did, ask specific questions about the implementation of your current tasks - ask if he can do it or not. Usually, he will not get a job that a person does not pull, or he will warn that he has not been specifically involved in such an implementation before, but is ready to study and overcome within en days / weeks. Inconsistency issues usually only arise with juniors or very weird types, but when looking for more or less experienced specialists at a competitive price tag, there are usually very few failures.

Answer 2

No way. Only at your own risk.
That is why it is important to know several technologies.
Or hire a competent team leader who knows a lot of technologies needed in the project
