The operator behind the system
I’m Alexander Chrisostomou. I lead Model Operator from Dubai, after product leadership roles across London and Stockholm.
I personally lead company brain installations. My work connects commercial priorities with the details of prototyping, automation, architecture and rollout.

Skills & tooling
The stack only matters when it supports governed context, source permissions, review loops, fast iteration, and commercial judgement.
Model choice matters less than the operating loop around it. I work where company memory, evals, permissions, review paths, and orchestration have to survive real traffic.

Thin teams need one thread from mobile and APIs to cloud and sequencing. I scope, write, and ship close enough to the build to keep decisions honest.

Built products
Company-brain work needs product judgement... That judgement gets sharper when it has to survive architecture choices, onboarding friction, analytics gaps, release cycles, and users who owe you nothing.
