My name is Reza Vaghefi. I am a Research Scientist working in high-tech hub of Silicon Valley. I have been teaching coding and machine learning for 5 years to college and graduate students. Working with more than 1000 students and helping them with solving interesting problems inspired me to create this website. This website provides a platform to help many people learn coding and solving problems. I believe coding is easy to understand, specially interpreted languages such as Python, R, and MATLAB. However, you only learn when you practice over and over. What makes this website different than other online coding websites is its diverse range of problems. If you are interested to connect with me, you can send me an email at firstname.lastname@example.org or contact me on Linkedin.
