Key Accomplishments

I have many years CTO and senior Engineering experience. I am a expert in building and scaling architecture (SOA) and technology, leading and hiring teams, defining technology strategy and delivering products. I have a broad spectrum of experience covering mobile, all type of online advertising, analytics, big data, RTB and more in both B2B and B2C products.

How I like to work with people As a Cofounder

I'm tenacious and willing to do whatever it takes. While I may have been a "developer", I have also designed product. Being able to design products and understand the technical architecture enables me to efficiently create and push out new ideas. I bring a high level of enthusiasm and drive to any team. I love entrepreneurship, and I love the risk. With the right idea, I pour my days and nights into seeing a company through to success.
