Experience of the developer

Conduct thorough research about the company and the team you want to work with. Prepare a list of questions to ask from the developers. This whole process will make sure that you know everything that you want to know about the developer. Knowing about how much work experience the developer has, what is his style of working and more is really helpful in choosing the right one for your project.


Having knowledge about the previous work experience gives you an idea about the kind of work the developer is capable of doing. Seeing the portfolio you can ensure whether or not the developer is the right fit for your project. Also, if possible talk to their previous clients to know in-depth about their services and the way they have managed their previous work.

Understanding of programming concepts

Blockchain development is a complicated process and a lot of things are involved in it. The developer must be aware of the basic programming concepts and languages like C++, Javascript, Solidity, Java, etc. Also, he should have a basic understanding of the following concepts:

Every company or Blockchain developer has their own process to follow. Since there are various development techniques available, you need to make sure what development process is followed by the developers.

Understanding of Blockchain concepts
