What's the difference
Overview

I have extensive experience in machine learning and data mining, including search engines, natural language processing, crowdsourcing and regression analysis. As part of my PhD study I also enjoy computer vision, especially what concerns face and emotion recognition.

Note: I already have full-time job, so I can accept only short-term projects that I can deliver with high quality in a reasonable time.

“What can I say about Andrei, he is technically smart, hard working and a great person to work with. He helped answered my questions and gave suggestion even before the project was awarded to him. He worked with me on every aspect from Requirements to Development and Deployment. He has great communication skills and responded to emails with few hours. We will be hiring Andrei again for our phase two requirements. I highly recommend Andrei, for any NLP or Java related projects. He is a whiz @ using GATE framework to make sense out of unstructured data.”
