About

Engineering manager with over 8 years in executive leadership and 18 years in software and infrastructure development. I have run high-load systems and optimised development processes — increasing releases from 1 to 30-40 per month — and built remote teams, growing them from 5 to over 40 people. A strategic approach to engineering keeps customer satisfaction high and business growth sustainable.
