About

👋 Hi! I’m Kuai, currently a Director of Engineering at a Fintech unicorn. With experience at Two Sigma, Google, and Citadel, I have a decade-long track record in tech and finance. I mentor both software engineers and managers, helping them navigate and succeed in their engineering careers.

My mentees have received offers from 30+ companies, including trading firms (Citadel, Jump Trading, HRT, Two Sigma, AQR), big tech (Meta, Google, Amazon, LinkedIn, Uber), and startups (Stripe, Databricks, CloudKitchens).

I started working with Kuai because I wasn’t sure what direction to take in my career. He helped me figure out what to focus on and gave clear, practical advice on everything from interviews to planning ahead. It’s been super helpful talking things through with someone who’s been at top companies and knows the industry well. I feel more confident and focused now. Highly recommend if you’re looking for guidance in your tech career.

Kuai is an outstanding mentor with tremendous knowledge, experience, and dedication. As a new graduate, I was initially struggling both to land interviews and to perform well during them. However, with Kuai’s guidance, encouragement, and insightful advice, I was able not only to significantly improve my interview skills but also to eventually land a job at Google. Beyond technical preparation, Kuai also shared valuable advice on workplace communication, collaboration with colleagues, and how to navigate the professional environment as a new hire. His mentorship has been instrumental in boosting my confidence and preparing me for success, not just during the interview process but also in my early career journey. I am truly grateful for his support and would highly recommend him as a mentor to anyone seeking to grow both professionally and personally.

He has a deep understanding of how recruiters and hiring managers evaluate resumes. His feedback on mine was incredibly valuable—I saw a clear improvement in response rates and secured multiple interviews using the strategies he suggested. He also brings strong expertise in both technical and behavioral interviews. The mock interviews I did with him helped me boost my confidence and performance. I’m truly grateful for his guidance throughout the process. Highly recommend his mentorship!
