Dusan is an engineer with Ruby on Rails experience. He believes that improving the tools you use (editor, code style, tests, CI) and sharing data (API, user notifications, reports) are imperative for an app's success. That's why Dusan writes modern, well-tested, and maintainable code that connects various services. Open-source software makes him a better programmer and gives him the tools to implement web ideas.
