I have been a lead developer and a system architect for over five years before becoming CTO of a pan-European dating company. In all my roles I was expected to design and build systems that handles millions of users varying from backend administration systems to the very site a user logs in to.
Familiar with online payment system integrations, fraud management systems as well as internal credit accounting system design and structure which all are critical in credit top-up systems.
In the past 5 years I never had a team smaller than 6 people. I have a strong entrepreneurial drive.
