Ron Liu

Lionel is the best developer I have ever seen before. I was absolutely surprised by his frontend knowledge with just several years' experience. He is capable of turning any tough problems into a solution with best practices. He is highly effective and always in flow state, he types super fast equipped with VIM proficiency, and his outcomes will beat 3 other programmers easily. He is easy to work with, always sharing what he learned and tried. I learned a lot from him. It is super fun when working with him. I will recommend him to any team if they need a super programmer.
