Profile
Twenty-three years keeping networks up, while moving them forward.
Bilingual network architect working at the seam between carrier-grade infrastructure and enterprise scale. My background started on national backbones — China Telecom CN2, the China Netcom northern core — and has moved through banking and telco in East Africa, HPC fabrics for genomic research, and now a global retail and logistics estate.
I own the whole path: architecture, delivery, and production support — including the incident calls that arrive outside business hours. The last five years have been dominated by transformation — legacy on-premise to hybrid cloud, MPLS to SD-WAN, and low-latency Ethernet for AI clusters — and by the automation that keeps those changes reversible.
