In this project I gathered several pieces of structured information on a collection of mobile phones from the Amazon website. Among theses pieces there is one important source of information on the phones which is the textual consumer ratings or text review.
In fact, the text review provides extremely useful feedback for producers, the information in textual reviews can be a lot more detailed that's why I apply the text mining by using a dictionary-based approach to classify the reviews as positive, negative etc...

Brahim is really skilled with the work that I assigned him to do, particularly in R software and machine learning methods. I also appreciate him asking for virtual meetings to also ease the communication between us. He also showed us his methods and how he accomplishes the project. I actually learned a lot about machine learning and using R software because of him. I really recommend him for projects that require data science in general. I will work with him in the future if given the chance.

It was one of the good experiences in my professional career. Brahim told me that building a shiny dashboard and forecasting models are something he does on a regular basis, also the data visualization and machine learning are his favorite works. He didn't ask for money right away; instead, he worked hard and smart without missing any detail in order to meet the deadline. He was kind, polite, and communicative. I'm sure I'll hire him again. In a nutshell, Brahim is a valuable data scientist.

Brahim was extremely professional in terms of taking over the work on time and communication with me. I informed him everything about the job and my budget, and he assured me that he would be able to complete it on time and on budget. The highest grade of work was produced, and it was even completed. It was difficult work, because it demanded a lot of focus and effort. Brahim achieved the desired outcome. Without a doubt, I will hire him again.
