How to form criteria for finding a frontEnd developer?

Question

Personnel Management

Over time, the project will need a front-end developer, we want to launch a project with 10-15% of the functionality at the start, and while back-enders are coping with partial competence in the front.
How to look for a future employee? Taking into account that now there is only those tasks, and a simplified front from which later only the layout will remain. We need a person who will decide for himself how and what should be done.
How to look for these? Provided that I can’t now throw a list of the necessary technologies into the text of the vacancy.

Answer 1

It probably depends on the estimated salary. There will be a good salary - you can find a specialist who knows many technologies and with good experience, you can understand by resume + portfolio. And if the budget for salaries is at a minimum, then how lucky you may get caught by a talented beginner or a snickering freeloader.
Well, from specifying knowledge of HTML / CSS / JS in the requirements, etc. zero sense. Most freelancers know them, but far from everyone is able and willing to apply this knowledge qualitatively.
I think it's better to give one-time paid test tasks and, based on the result, select suitable candidates for further conversation.
