Christian Szilagyi

I run Contigo Services — a fractional CTO and technology consulting practice based in Melbourne, Australia. My clients range from AI infrastructure companies and ASX-listed enterprises to startup accelerators and venture capital investors.

Most recently, I served as CTO of an AI infrastructure company where I directed a technical team building a GPU compute marketplace and orchestration platform, and designed a 20MW purpose-built GPU datacenter in Romania. Separately, through my consulting practice, I designed an additional four GPU datacenters totalling 240MW across Australia and Romania, specifying multi-generational NVIDIA architectures from A100 through to latest generation.

Before consulting, I was Country Manager twice — launching Calabrio and Centrical into Australia/New Zealand from zero, building teams, partnerships, and multi-million dollar pipelines at both. My foundation is a decade as a full-stack software architect across fintech, banking, and telecommunications.
