When looking for a developer you should choose the one with aptitude not a specific skill. With increased changes in technology most of the skills are becoming useless within a short period of time especially 2 years. Thus, why hiring a developer with specific skill will not be of help to you as such a person cannot easily acquire new ideas. With this it is recommended that you employ a web developer that will be in a position to adapt to the current changes and use current methods. You can achieve this by asking the developer questions that proves whether he is ready to acquire new ideas. For instance, you can ask the developer about places where he always go to acquire new skills.
To know the best web developer it is important that you stop asking trivia questions. This is not enough proving to show you that the developer has enough skills as in handling your projects due to the fact that it can be searched into the internet directly. Have you ever seen people who can explain to you what needs to be done yet they cannot do it? Thus, the same thing with people who can answer all your questions and they cannot develop a proper website. One of the best ways to prove skills is to use open ended questions. With this you will be sure that he is telling you what he knows being that these questions cannot be searched on the internet.
Another tip in finding the best web developer is to hire slow and fire fast. It is always a rule that you take your time to hire someone than firing. You will need to verify the credentials and conduct interviews which you will not do when firing. When you realize that the developer that you have hired lack the capacity you should fire him immediately and look for the right one.
Another thing that you should do is to start with a smaller project. It is clearly not possible for a person whom cannot handle small project to handle a bigger one. What you are suppose to do is to assess how he is handling the project and the duration of time that he takes.
Lastly, you should also concentrate on the license. This will help you in knowing that you are dealing with a professional. You should know that the better your web is made the more successful you are likely to be. Quacks are not the best option since they majorly depend on guesswork. This is an assurance that you will get high quality work.
