Independent CTO & executive advisory

Technology
decisions
you can defend.

Decide what to fund, what to stop, and how to deliver. Tie technology spending to revenue, operating cost and the business’s ability to grow.

I’m Christian Prokopp. I combine CTO and CDO experience with hands-on engineering, helping CEOs, founders and leadership teams connect strategy with systems they can build and operate.

03 / Technical work behind the advice

Close enough
to test the advice.

A focused prototype can test an important assumption before committing significant budget. I combine that practical investigation with the architecture and engineering needed for production.

I built the Semaverse.ai research platform, connecting agents, source data and working documents, and helped Camunda develop early AI prototypes that informed its product and technology direction.

Tax Shrink, Llamar and Turmberg are independent projects in development, not client case studies. Each needs human review before wider use.
