How to prevent being led by the nose by a freelancer / programmer?

Question

Business Informatics

Foreword: please don't write tips unless you've hired a programmer or outsourced the project to freelance. The opinion of people who are not from coding, who don’t rummage about in it, but manage to control the timing and budget, will be interesting.
For example, I have a design and a required functionality (TK). I give it to the programmer. Here are the questions:
1) how to determine if he designed the architecture correctly, whether flexibility is built in (I'm just surprised when I see good code for products without big budgets and this is managed by a marketer who stupidly hired a programmer)
2) how to make sure that the programmer is able to adequately determine the implementation period? It seems to me that not everyone is capable of this and praise to those guys who plan and do everything on time and do not burn at the end of the term
3) how to communicate with a programmer so that he does not consider me Satan, who demands everything at once
4) give advice about pitfalls not mentioned here, send links to articles from life situations about such small teams
, I myself have little experience in freelancing and I understand that it is rather a question of the programmer's conscience when the customer is a noob.
I'm afraid that while I become a mother, they will milk me well (and I'm not a rich guy and money from savings)

Answer 1

Are you asking programmers? :)

Answer 2

Your problem is that you see that an hour of a freelance programmer's work costs a conditional 1000 rubles, and you think that it is.
But in fact, the real price is 2000 rubles. An hour of work for a programmer, and 15 minutes for someone who will check.
Freelance exchanges are for those who are ready to work as a "checker", and not for those who want to stupidly save money. For the rest, there are web studios and other outsourcing companies that are much more expensive.

Answer 3

These things are handled by a technical director or a project manager. And they are usually former programmers.

Answer 4

1. See if he has past successful long-term projects, get him interested in something.
Without large budgets managed by a marketer, a person was either very interested in the project, or he was in a share.
One task, not an interesting project, there is no chance to raise money for you in the future - a shitty year is highly likely.
2. The vast majority are unable to adequately determine the implementation period. If he is experienced and smart - multiply in your mind the time indicated by him by two, if there are problems with experience - by five.
3. Be fair. Do not suffer from the complex of a small boss. If you are very lucky and you have found a good programmer - remember, he needs you much less than you need him.
4. Experience will not replace any tips and stories, the main thing is not to be afraid of defeat and try.
