👋 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 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.

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.
