I am taking a course in Machine Learning and worked on some highly difficult problem sets stumping even some 5.0 star experienced Machine Learning tutors on Wyzant. When messaging back and forth with Andrew, I acknowledged his steep price and he made it sound as if he could work through these problems with me easily. He knows a lot in general but even after sending problems and solutions to him in advance, I sensed that his knowledge of some of the problems were subpar despite the confidence he puts forward with his messages and hourly rate. I was hoping that one of the highest priced tutors in this domain would come more prepared and the higher the price the higher my expectations of value a tutor brings. Also there were times I found his explanations rushed and I had to extensively research some things even after the session.

Explained very complex optimization techniques and methods with ease, simplicity and high clarity. I definitely recommend him as he has high and great knowledge within several subjects.

Andrew really knows Python and also knows how to interpret and apply Python to solve difficult data science problems. He is actually extremely quick at it too! His demeanor is very pleasant, kind and patient and seems to enjoy teaching others. What more can I say except I really believe he is gifted, a genius!

I am doing a Masters dissertation and have only been using R for a few months. Andrew was fantastic and helped write the code that I needed to run my data analysis. I would have been lost without his help. I have learnt so much.

Andrew helped me with my Machine Learning Homework. he knows his stuff very well and he explains clearly. He helped me to write code in Python to solve a problem about classification. Andrew was able to find a solution to every curveball I threw at him, and it was obvious to me that he has significant experience with different programming languages. I definitely plan to have another tutoring session again with him for any future help with Machine Learning. Thanks Andrew.

Andrew is very helpful. Solved my problem with an innovative way. He has much experience with data. I would recommend him to anyone who has a problem with data.

Andrew taught me how to calculate all kinds of ratios from insurance companies' annual report and how to conduct the profitability analysis. Andrew has a great amount of knowledge of actuarial and the teaching is very helpful! Thank you.

Andrew is intelligent and knowledgeable in a multitude of subjects including mathematics and programming. Coupled with his vast range of expertise, he is also kind, patient, and an exceptional teacher. It is an absolute joy to work with him and he has taught me a great deal. I have improved immensely under his guidance and each lesson with him always exceeds my expectations.

Andrew helped me write code in R to read and manipulate some very poorly formatted files. Andrew was able to find a solution to every curveball I threw at him, and it was obvious to me that he has significant experience with different programming languages. I definitely plan to talk to Andrew again for any future help with R!

He is very knowledgeable in the field, and good at teaching. He helped me with efficiency. Very professional! I would love to have more tutoring with him again.

Andrew was SO helpful to me in determining how to attack a data set. He taught me as we went and explained everything in an easy to understand way without over-complicating things. He is patient, and incredibly knowledgeable about data/statistical analysis. He does this for work so he knew how to quickly attack the problem and describe it to someone ?new.?

Andrew's grasp of the AP Stats content was evident from the beginning of the lesson through to the end. He carefully went through the concepts scaffolding where necessary and pushing and holding high expectations with a calm kind demeanor.
