Vasileios Tsakalos

I am an experienced R programmer with hands on experience on machine learning projects, data visualization projects, data processing and web application projects ( Shiny package). I am also a freelancer contributor at the website r-exercises.com which aims to enhance the programming skills of amateur R programmers by challenging with exercises that have been created by experienced programmers.

I am a full-time data scientist with tools of choice to be python. The projects I am working on regard NLP, computer vision and pattern recognition. When it comes to pattern recognition I mostly use the popular (and less sophisticated machine learning algorithms) but when it comes to computer vision and NLP problems I am using deep networks (mostly convolutional neural networks).
