"Quality is much better than Quantity, One home run is much better than two doubles." ___________Steve Jobs My chinese name is Yu Jun, nickname is Donnie Chan. Don't confuse my wide knowledge with a lack of focus. I am a groundbreaking software developer who thinks like an end-user, who thinks that 90% done is only half done. All of my products were implemented according to MVC, MVVM and EBI design patterns. In terms of QUALITY, I always write code which will withstand millions of users hammering on it and my code works smoothly without any crashes. Everyone says that my code is clean, modular, robust, portable, reusable and easy to maintain. I have strong skill in PHP, MySQL, Node.js, React.js, Angular.js, C/C++, Java, Python, .Net, Objective-C, Swift, C#, Qt, Linux.
