Bio
Ola Podgorska
Having been lucky to work with Vas on the Digital team at RY at the beginning of my career, I can highly recommend his ability to cut through the chaos, and to focus on exactly what needs focus. I learnt a lot from Vas as he would always have the time for us and even though I didn’t work directly under his line management, I definitely benefited from sitting next to the Dev team and learning about systems architecture 🙌
Jiri Mocicka
Vas and I have a long history starting at R/GA 2010 and continuing throughout several ventures big or small till the very present day. I have always been surprised by his pragmatic and efficient approach to development. Many campaigns, retail solution and product integration, went through his hands. He helps businesses to strive through digital transformation, build the products that customers appreciate the age of connected experience as well as foster well-orchestrated development teams he forms around himself. You can find him at @fasoulas.
