In a proper way. Obeying standards, coding friendly and using explanations, comments and documentation. I know this is important because I have painful memories when refoactoring someone else's code.
Using proper technologies. Not over engineering. If the best technology is node.js in a project, I use the one who fits and having best performance.
I work by the book. I know that other people would work on the code too.
I have an excellent knowledge about the technologies that I am expert and I don't invent unnneccessary things if I don't know how to do. I analyze the problem. I research and find the best solution.
