We design, build, and keep running the information systems that can’t afford downtime — from a registry with millions of records to an e-shop that has to handle real customer load. From the Czech Statistical Office to Černý rytíř.

Architecture, technology choices, and a scope estimate — you know what you’re getting into before a single line of code is written.
We build in verifiable stages, not as one large delivery at the end — you see progress along the way.
Installation, documentation, and staff training — you take over the system with a manual, not a list of open questions.
We keep watching the system after handover — it’s why systems built in the 90s are still running with the same vendor.
