Hi!

My name is Jerome Tissieres – “JT” is easier to shout across a data centre than my full name…

Welcome to my blog!

Jerome 'JT' Tissieres, Network Engineer/Architect in Switzerland

About me

I am a technical leader and network engineer/architect based in Switzerland. I’ve spent over 30 years at the heart of the evolving IT network landscape. My journey began in the early days of Internet dial-up and has led me to large-scale HPC / AI cluster interconnects. Whether I’m acting as a hands-on engineer or leading cross-functional teams, my focus remains the same: operating at the intersection of high-performance engineering and people development. In 2026, after years of preparation, I earned my CCDE #20260037 certification.

I have also been selected as a member of the Cisco Champion program for six years. A group of highly influential technical experts who enjoy sharing their knowledge, expertise, and thoughts across the social web and with Cisco.

About this blog

In this technical blog, I try to cover a wide range of networking hardware, systems, and vendors. Including Cisco, Meraki, Huawei, and NVIDIA (Mellanox & Cumulus). I’m also interested in the details of the different software for network planning, design, operation, troubleshooting, and automation. In addition, I leverage my own learning experiences in network engineering, automation, a bit of software development/scripting, and various cloud solutions. More recently, I’ve also been writing my thoughts and advice on various aspects of the career of a network engineer and a technical leader. Whether you are a fellow architect or just starting your networking journey, I hope you find something here that helps you.
