Hi! I'm Amir Masoud Sefidian
Data Science / Machine Learning
W
elcome to my website! I wrote my first lines of C++ for AVR microcontrollers at 14, building robots with my high school team. That passion led me to a Master’s in Computer Engineering (2017), where I dove deep into Machine Learning, especially making sense of messy, incomplete data. Now, I am a Data Scientist at Vinted, improving search and reranking systems to help people find what they love, smarter and faster. I also share helpful stuff I learn throughout my journey on my Academy/Blog to simplify concepts in Machine Learning, Mathematics, Programming, and related topics.
When I'm not coding, you'll probably find me at the piano or lost in music!
