Nickolas Makrodimitris,

Talented, communicative, problem solver and always kind – these are few of the words that come to mind, when I think about Vasileios. Plus “cool” for that matters.
I have had the pleasure of working with him at the BaaS digital media agency in Athens, Greece. The thing is, even though I’m a Copywriter and cannot fully comprehend many things about ads performance, metrics and data analysis, he has helped me a ton with his tips and pieces of useful advice and information. He also is a great multitasker, a skill which I can appreciate, since it’s extremely significant in digital marketing campaigns.
Always patient in times of crisis, there have been many times Vasileios has saved the day for me and my colleagues. So, it’s more than accurate to say that he would be a great asset to any team and any company.

Konstantinos Poulios,
Co-Owner at Eltekpoulios
I am glad to be calling Vasileios a close friend of mine. He is a hard-working, enthusiastic, multi-talented and insightful professional with strong problem-solving skills. We have worked on several projects together and he brought to the table his insights, knowledge and unique perspective to each and every one of those, but his biggest talents would have to be his true leadership, bringing out the best of everyone working with him and his ability to take a step back and take a look at each case from a small distance allowing him to provide unique solutions. He is truly wise and you would never believe he has already accomplished that much at such a young age while still maintaining his “hunger” for more. A true asset to any team.

Dionisis Stathakopoulos,

“Getting the job perfectly done” is the phrase that comes to mind when I think about Vasilis. He is a hard-working, enthusiastic professional that would be a great addition to any company. I have the pleasure of knowing Vasilis for a couple of years, during which we have had the chance to work together on major digital campaigns for global clients like Friesland Campina and others. Above all, I was impressed with his ability to work fast and under pressure. And of course, his friendly personality and above all his great sense of humor would be true assets for any positions requiring a well trained and qualified professional.
