You’re the person we’re looking for if you:
— have worked with modern web frameworks. You not only tried to use React.js, but also looked into its source code out of interest;
— familiar with modern assembly tools. You can imagine how webpack or gulp work;
— know how to work in a team. You know (or at least guess) why scrum and agile are needed, how to use git-flow and why you need code reviews
— have good enough English for reading technical documentation.
