Operational telecommunications
Understanding of networks, critical communications, availability constraints, latency and interconnection.
About
A technical pivot between IT, OT, engineering and operations
RĒSUNIX is rooted in a field-based understanding of technology evolution: operational systems and IT are converging, while their cultures, priorities and constraints remain different.
Origin
A vision built on experience
RĒSUNIX was founded from an analysis built over several decades of experience: information technologies, electronic systems, servo-controlled mechanical systems, telecommunications and real-time environments are progressively converging.
Industrial and real-time systems
Experience with field systems, PLCs, RTUs, automation, monitoring and deterministic environments.
Cross-functional profile
Ability to connect business priorities, field realities, engineering constraints and cyber requirements.
Background · Vision
A cross-functional reading of critical environments
This vision was shaped through experience connecting multiple realities: industrial field systems, telecommunications, cybersecurity, supervision, integration, specialized systems and the gradual convergence of OT and IT.
