I work as a software engineer. Previously, I worked at Twitter and Amazon. I graduated in Computer Science from an Ivy League university.

I have mentored numerous people who wanted to further their careers in tech. I have helped them become stronger programmers, such as teaching them algorithms, data structures, and system design. I have gotten them ready for job interviews, and most were able to receive a job offer. I also help fix their resumes so that they can get their foot in the door easily!

My clients have gotten competitive job offers at top companies, such as Amazon, Square, and DoorDash.

I had one mock system design session with Yen. Starting from defining functional and non-functional requirements, he gave me very thoughtful feedback about how to focus on critical feature requirements as well as the importance of providing metrics to describe the expected latency and tolerancing downtimes. Then, we spent some time going through my high-level design, also, defining DB Schema plus API. Still, Yen gave me tons of valuable advice about how to scale up the system, how to handle requests in real-time using Kafka, and correct my DB design as well. I feel very comfortable chatting with him and to be honest even though I was a little bit frustrated due to my not-so-good performance during the mock interview, his encouragement made me eager to work harder on preparing a system design interview to fill up the knowledge gap! Thank you Yen, I will recommend him to anyone who wants to evaluate themselves or be ready to be interviewed to have a mock interview session with Yen.
