👋 Hi! I’m Kuai, currently a Director of Engineering at an AI startup. 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 (Google, Meta, Doordash, LinkedIn, Coinbase, Amazon), and startups (Glean, Databricks, Stripe).
5 out of 5 stars
Kuai has been an amazing mentor who genuinely cares about helping others grow. His mix of technical expertise and management insight made a huge difference in my career journey. He guided me through everything—from salary negotiations and system design to behavioral and technical interviews—with patience and clarity. Thanks to his mentorship, I was able to build my story, gain confidence, and successfully navigate one of the toughest job markets, ultimately landing a great role at a great company. I couldn’t recommend him more highly to anyone looking for a thoughtful, knowledgeable, and supportive mentor.

Kuai is an excellent mentor. He patiently listened to my concerns and helped craft a plan that was best for me. I approached him because I needed a solid, structured plan to crack LeetCode questions. He set up regular calls throughout the month to check in on my progress, and was also available on chat whenever needed. I really liked his approach to building up my LeetCode skills systematically. He's genuinely one of the best mentors I've worked with, and I'd recommend him to anyone.
