My name is Bob Lee originally form S.Korea. I'm a full-stack developer proficient in server-side swift and iOS development. I focus on the fundamentals of iOS development which often developers neglect. I believe most problems can be solved by understanding the root. My teaching philosophy is to provide as many as practical problems within each lesson and then students are able to apply in their own projects. I love teaching because it is the only way I can have great impact on people's lives at this point of my life. I work towards building long-term relationships with the students over short-term sales.
