🚀 From Engineer to CTO – Now Helping You Get There Too
I’ve spent the last 20 years in engineering – 15 of them leading teams – and I know firsthand how challenging it can be to scale a team, optimize processes, and grow as a leader without losing your mind (or your culture).
As the CTO of bitmovin, a fast-growing scale-up in the media tech space, I’ve:
✅ Scaled engineering teams from 15 to 100+ people
✅ Coached 50+ engineers and managers in transitioning from individual contributors to leaders.
✅ Solved critical challenges like hiring bottlenecks, process inefficiencies, and team conflicts
Why work with me?
I don’t just give advice, I will help you find your own answers. My mentoring style is pragmatic, action-oriented, and tailored to your unique situation. Whether you’re:
A first-time engineering manager struggling with delegation,
A tech lead looking to scale your team without chaos,
OR A CTO or Head of Engineering needing a sounding board for tough decisions
I’ll help you get unstuck, make better decisions, and grow with confidence.
Let’s build something great together.
