Bio
Anne Goujon
I had the pleasure to work with Nikolaos during his 6 months traineeship in the LIST. As part of the collaboration between LIST and BGL BNPPARIBAS, Nikolaos was integrated in the Bank Data Science Lab. I greatly appreciated his contributions to our Data Science projects, and his enthusiasm to work on any new use case. During these 6 months, he has successfully demonstrated his technical skills in Machine Learning, even improving the learning capacity of our models and contributing to the visualisation of high dimensional data. Nikolaos demonstrated a quick capacity to learn and to be operational. I particularly appreciated his proactivity and ideas in our brainstorming sessions. He proved to be an excellent valuable asset.

I had the pleasure of working with Nikolaos during his work at our team at Krataion Consulting. Nikos worked as an Online Advisor where he had to educate, consult and train travel SMB on the value of digital. He led 370 consulting engagements with businesses in the hospitality sector during a period of only 5 months. Nikos obtained a satisfaction score 4.77 out 5 for his individual performance – placing him at the top 3 out of the whole team of 20 Online Advisors. The special attribute that led to this exceptional feedback was his ability and patience to explain complicated things in a very comprehensive and structured manner to business owners. His positive attitude and solution based approach as well as his strong teamwork have been Nikos strongest attributes. I would strongly recommend him as I believe in his qualities, potential and skills.
