Even if I never have worked for a company that had an open source culture, I still contribute to the Web / JS community as much as I can. I love talking at local meetups (Seoul, Tokyo and Montreal) or taking care of developers debuting in web development. E.g. I've made a list of free content for people debuting with ES6/2015 and React. All interns I've worked with have said I was a good mentor 😳. I also enjoy doing internal presentations or sharing articles to introduce new concepts or libraries to my teammates. I am also used to do pair programming to solve problems in a more efficient way.
