"Excellent Tutor, Helpful in Many Aspects!"
- David, San Ramon, CA on 7/17/16Ruben is a great instructor and an incredibly valuable resource due to his various skill sets. I was taking a very difficult C++ summer course at a college, and even though I was a beginning programmer, Ruben did an incredible job of guiding me through the course's lessons and explaining many difficult concepts. His attention to detail, precision, and knowledge of C++ (and other programming languages) proved extremely useful. Additionally, Ruben is punctual and dedicated, and he really seems to enjoy teaching. I could not have asked for a better instructor to introduce me to a field that was completely new to me! The fact that he can teach computer science, math, and Spanish at a high level is truly remarkable. I'm looking forward to continue working with him.
