Vitaly Dubravin - CTO

Job Titles:
  • Chief Technology Officer
The scope of my leadership career, often in lean environments, ranges from Fortune 100 multinational organizations to the high pressure, demanding and fast-paced world of high-tech boutiques. I was delighted to be a part of the Hewlett-Packard Consulting transformation as a practice manager, Y2K Country Campion, as well as a USAID and Deloitte and Touché project lead. After switching my focus to the smaller companies I've built the Microsoft technology practice from the ground up as CTO at GRT and defined and executed the agile product development process as COO at Kindle Innovations. As CTO at r4, I am an enthusiastic and innovative organizer of our world-class technology team dedicated toward joint success, and for our clients, bottom-line performance where it counts. I love r4's constant drive for innovation, creative thinking and an opportunity to challenge "impossible."
