Expert Consulting Services

Bringing Big Tech expertise to European businesses

Fractional CTO | AI-Augmented Development | Privacy-First Infrastructure

Why Europe Needs This

US big tech offers power but raises privacy concerns. European companies need the same capabilities built on EU values.

  • Self-hosted infrastructure, GDPR compliance, data residency
  • Lessons learned at leading US tech companies applied to European standards
  • Privacy-first architecture without sacrificing capability

A decade of experience at companies like Uber, Postmates, and HERE - now building technology that respects European values.

Fractional CTO Services

Senior technical leadership for growing businesses. Get the experience of a seasoned CTO without the $400k-$800k full-time commitment.

Why Fractional?

Engineering leadership at companies like Uber, Google, and Meta commands $400k-$800k+ in total compensation. That's the caliber of experience you need to make the right architectural decisions, avoid costly mistakes, and build systems that scale.

But most growing businesses can't justify that expense full-time. A fractional arrangement gives you access to that same experience on a part-time or project basis.
