I am European, however I have worked with developers from various parts of Asia and South America. English is usually a second language, however most developers are fairly fluent using it as a spoken or written language. Also, most development resources are written in English, so all developers know how to read it. Programming languages and their standard libraries are also written in English. It's the lingua franca worldwide, so we are all happy to use it in the technical context.
