Bernat is a patient teacher with a wealth of experience with D3.js. He is methodical about understanding and debugging the code, and he has a calm manner.

Bernát is very knowledgeable and literally only took a few minutes to do a complex D3.Js chart in Django. Very impressive!
He is very strong in JavaScript and Python. I look forward to continue to learn from him.
