Hi! I'm Amir Masoud Sefidian
Data Science / Machine Learning
W
elcome to my website! I started programming as a C++ developer for AVR microcontrollers when I was 14. After four years of programming for the high school robotics team, I was motivated to pursue Computer Science. I completed my Master's degree in Computer Engineering in 2017 where I worked in the field of Machine Learning and Data Science especially focused on data preprocessing and missing values imputation techniques. Currently, I am a Data Scientist with a passion for developing innovative algorithms and models that can drive insights and value at Vinted. I regularly share some content that I find useful throughout my learning journey on my Academy/Blog to simplify concepts in Machine Learning, Mathematics, Programming, and related topics. Besides computer science, I enjoy playing the piano and listening to music.
