Great!

Qi helped me with an incredibly challenging divide and conquer algorithm. I had been looking for a solution for days and he helped me find one!

John, 1 lesson with Qi

super knowledgeable and helped me a lot

I'm a Ph.D. student an he helped with my research (MD simulations), he reviewed my code and explained to me the concepts and we code a solution together. He was able to help super fast, I highly recommend him

Fae, 1 lesson with Qi

Clear and Professional!

Qi really helped me on the road map of my search. He was very attentive to my questions and professional in showing me how different subjects were structured. I am very pleased with the information density and the insight he provided. With Qi’s guidance, I can learn a lot faster with much less friction. Highly recommend!
