Welcome. I'm Kuba
I help early-stage founders turn messy ideas into working software—without hiring a full-time CTO.
Based in Wroclaw, Poland. I love the chaos of 0-to-1: the whiteboard sessions, the "figure it out as we go," the tight deadlines.
Give me a messy problem, a whiteboard, and a tight deadline—that's when I'm happiest. I've spent the last 5 years jumping into early-stage projects where everything needs to be figured out: EdTech platforms, FinTech marketplaces, real-time captioning systems.
The pattern I keep coming back to? Founders who need someone to translate "here's what we want to build" into "here's what's actually running in production." That means asking hard questions about priorities, gathering requirements when planning is weak, making architectural decisions that keep things flexible, and shipping fast.
I care deeply about two things: shipping fast and not creating a mess. Those shouldn't be opposites, but somehow they often are. I use Domain-Driven Design to keep architecture flexible (because you'll pivot as you learn from users). I use modern AI-assisted workflows to ship faster without sacrificing quality. And I think most technical decisions are actually business decisions in disguise.
When I'm not building software, I'm writing about what actually works when you're moving fast.
Let's see if we're a good match
