I’ve had five careers inside one.
Not because I job-hopped. Because each environment forced a different kind of growth — and no single environment could have forced all of it.
My first job: part-time developer, production code from day one. Software either works or it doesn’t. No partial credit.
Then I built my own company. Negotiations, client management, selling what you’d built. Suddenly the code was the easy part.
VeriPark: long, high-stakes delivery across EMEA. Senior stakeholders who needed to come with you, not just be informed by you. The job title said “architect.” The real skill required was alignment.
Booking.com: what scale actually means. Not “a lot of users.” 10x thinking, 100x thinking. Teams that don’t just survive growth, they compound it. I had to unlearn almost everything I knew about what fast looks like.
TomTom: influence without authority. Leading a 100-person platform org serving 1,500 engineers means your customer is internal. You earn trust through what you build, not your title. And when platform spend reaches the kind of scale that makes every Finance conversation a strategic one, you realise financial fluency was never the CFO’s job alone.
None of these lessons transferred from the role before. Each one required a new environment.
The leaders who last aren’t the ones with the most credentials. They’re the ones who kept expanding their range, long after they had permission to stop.
The order doesn’t matter. Some learn to sell before they learn to scale. Some build teams before they build companies. What matters is that you keep adding layers.
What’s the layer you’re focused on building right now?
The credential doesn’t teach you the next one. The environment does.
