Read ArticleI am an engineering leader with over 20 years of experience working on large-scale packet networks in Service Provider and latency-sensitive environments.
My work has centered on end-to-end architectural ownership of backbone and edge infrastructures — spanning platform and vendor selection, routing and control-plane design, and the evolution of networks under real operational and economic constraints. These systems operate at scale, where performance, reliability, cost efficiency, and long-term sustainability must be balanced deliberately, not optimised in isolation.
Over the years, I have been closely involved in multi-vendor environments, platform lifecycle decisions, and the unification and simplification of complex networks into cohesive, production-grade systems. A significant part of this work involves driving optimisation, enabling lower-cost technology adoption, and making architectural decisions that improve operability without sacrificing correctness or resilience.
PacketBytes is a personal space where I document the engineering thinking behind these systems — examining architectures, control planes, and design trade-offs as they behave under real traffic, real failures, and real operational pressure, beyond configuration and into intent.
