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 (Google, Meta, Doordash, LinkedIn, Coinbase, Amazon), and startups (Glean, Databricks, Stripe).

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.

I wish I had Kuai as a mentor earlier. He completely opened my eyes to how promotions and other internal processes work within a tech company, and made me to consider perspectives beyond my own. He changed the way I look at communication with others - both at work and in life.

After spending nearly two years trying to land a good tech job without much success, I was feeling lost and unsure of what direction to take. That’s when I found Kuai. His experience in the tech industry and thoughtful perspective gave me exactly the clarity I needed. What stood out the most was how Kuai helped me understand the hiring process from the other side, what recruiters and hiring managers are really looking for. He gave me specific, actionable advice at every step: how to improve my resume, how to stand out in interviews, and how to position myself as a strong candidate. His guidance was always tailored to my background and goals. With Kuai’s help, I finally landed a great new job within just a few months. I genuinely felt a shift in both my confidence and my strategy, and I now feel much better equipped for the long run in my career. Highly recommend Kuai if you’re feeling stuck or want a clear edge in your tech job search.
