Architecture therapy for overengineered stacks. Helping teams unship the microservices they didn't need.
I'm Grzegorz - a classically-trained engineer who helps teams build resilient, performant distributed systems 馃憢
I help companies get their architecture back on track - stop overengineering, tackle the 'impossible' consistency problems - with a pragmatic, delivery-driven focus and no cargo-culting.

Train your team, untangle an architecture that's gone sideways, or mentor your seniors 1:1 - it starts with a free, no-commitment call. Not ready? Read how I think at 4comprehension.com.
Modular, tailored to your stack and your actual problems, hands-on - built around the systems your team ships, not a fixed curriculum. We scope what your team needs in the free assessment before anyone commits.
