“Matei is great! Super patient for a non-technical person and provides very intuitive explanations for what is happening in code (e.g. server talking to client, client talking to stripe). Also is very adaptable to each person's needs (fast at referencing developer tools). Highly recommend!“

“Denys is a very patient mentor. His way of teaching is to help students thoroughly understand how something works step by step, rather than teaching only to solve a specific problem. This is my first time working with Denys, and I will continue learning with him in the future.“
