Rudolf Run Ltd is an independent software architecture and security consultancy. We help enterprises stabilize complex systems, harden security posture and modernize technology at scale.
Deep expertise across the full spectrum of backend engineering — from architecture design to production security.
Design and implementation of scalable, maintainable backend architectures for enterprise-grade systems.
Security-by-design methodology for systems operating in compliance-sensitive and high-trust environments.
Strategic advisory and hands-on delivery for organizations facing complex technical challenges.
Cloud-native and hybrid architecture design with a focus on reliability, cost efficiency and operational excellence.
Optimization of system throughput, response times and resource utilization under real-world load.
Legacy system migration and code modernization without disrupting production operations.
We combine the depth of a senior architecture practice with the agility and directness of an independent consultancy.
Rudolf Run Ltd was founded to provide enterprise organizations with direct access to senior-level software architecture and security expertise — without the overhead of large consultancies.
Our engagements are built on long-term trust and measurable impact. We don't advise from the sidelines — we take ownership of critical systems, write production code, and serve as the quality and security gate.
From stabilizing delayed projects to serving as the long-term architecture backbone, our track record demonstrates that deep expertise and hands-on commitment deliver results that scale.
