Building assets,
not just features.

I'm Karol Modelski, an Enterprise Angular Architect who treats code like financial leverage. I help founders Scale their impact, not just their technical debt. I build predictable, high-velocity systems that drive valuation.

Engineering_Strategy

"Velocity is the only metric." But velocity comes from stability, not shortcuts. I prioritize architectures that let you delete code, not just add it. My goal is to make your engineering team boringly predictable and dangerously fast.
