Colleagues describe him as "I had the privilege of working alongside Si Cheng aka K for 3 years at Yuzu. If you wanted something done quickly and done right you'd just ask K. He cared deeply about the quality of his work and of the complex system we built. K took the time to learn the system and became the go to person to ask. I look forward to working with him again someday.", "K is a terrific developer who I enjoyed working with as a developer and as his manager. K excels at getting tickets done quickly without sacrificing correctness or code reliability. As K’s manager, I often had to find additional tickets because he would build new features to there specification so quickly with strong test coverage and good practices. As a manager, I never had to consider whether K wouldn’t complete a sprint. Besides working on new features, K has an excellent mind for debugging and finding the root cause of an issue. If a severe urgent production bug occurred, K was my go to person on the team because I knew he could figure it out and get it resolved expediently. K had an incredible knowledge of all our services and domain logic which he obtained by working closely with other team members or building himself our admin system and e-commerce systems with financial reporting & auditing reporting. K is a full stack engineer. He is equally talented and comfortable working on front end code or backend server code. K was an invaluable member to the Yuzu ES team and great team member. I really enjoyed collaborating with K at Yuzu.", and "I highly recommend K. He is an excellent developer; both creative and technical. I managed K, and I also had the pleasure of teaching him. He learns fast and loves to figure out things on his own, which is a rare quality. I especially appreciate his creativity. I trained him to be a full stack developer, including design. He has talent. Personally, K has an upbeat positive attitude. He laughs very easily, which is infectious in the office. He's always very appreciative of my guidance and mentoring, and I'm pretty sure not a single team member dislikes K. He only has a few years under his belt, but as he gains experience he will become a very good senior developer, of this I'm sure. When he is available in the future I will definitely hire him again."
