This is just the start of my journey.
Khai (Jack) Nguyen
Software Engineer
USA
Greetings!I'm a software engineer focused on web and mobile development, which is now where I do most of my work. I enjoy digging into the business and customer needs behind a project. I ask the right questions to find the real use case, then design a solution from there, instead of just building the first approach that's suggested.
