Recommendations
What people I've worked with, say about me!
Leonardo Viapiana
Application Consultant @ TXT e-solutions
I have been working with Sotiris during the last months and I can proudly say that he is one of the most creative people I have ever met. He is brilliant, always ready for the change and a -not common- thinker. Apart from his great design skills he has a fine taste that allows him to always work effectively and differently from others. Every time I asked for something, he has always surprised me.
I recommend him because of his great professionalism, high commitment and effective lateral thinking.Gordon Ching
Chief Digital Officer @ AIESEC International
Working with Sotiris is always a pleasure. He is a creative individual who is committed to delivering excellence. Having worked with him as his team leader, he is always proactively working with me to rethink and ideate great initiatives to move our organization forward. One of his core strengths was the ability to learn fast, understand abstract concepts and bring them into something more practical and turn it into an executable action plan with the team.

Business Development Manager @ 100mentors.com
Working with Sotiris was a great experience. He manages to work hard, support his teammates and achieve his goals at the same time. He is definetely a teamplayer and his passion for impact is unique. Moreover, he is one of the most creative persons I've ever met and he comes up with brilliant ideas to increase the organisation effectiveness all the time.
Brian Barjami

Besides being a joy to work with, Sotiris is a take-charge person who is able to present creative ideas and communicate the benefits. He has successfully developed several marketing plans for AIESEC that have resulted in the clarity of the organization and increased revenue. In addition to being an asset to our marketing efforts, Sotiris was also extraordinarily helpful in other areas of the organization. In addition to presenting effective sessions for empowering our members, Sotiris assumed a leadership role in our meetings, inspiring and motivating the members of our committee .
