Build. Engineered with the team: a Varnish and Nginx CDN-in-a-box, the dashboard, and git-based configuration workflows, backed by Grafana, Elasticsearch, and Kibana, exposed identically across dev, test, and prod. Binary-equivalent behaviour from laptop to production, eliminating the configuration drift that defined the incumbent CDN experience.
Adoption. Hardened the modular edge stack (Docker-native Varnish, Nginx, PageSpeed) against early enterprise workloads. Hotjar, NIB, and the Australian Magento and BigCommerce cohort: Temple & Webster, Appliances Online, Adore Beauty, Lorna Jane, Princess Polly. The developer-first CDN powering the operators that defined Australia’s 2010 to 2015 online retail boom.
Trajectory. Ran head-to-head proofs on customer workloads against incumbents. Deal-winning numbers that grew the platform out of its Australian origins toward the Boulder HQ relocation (Foundry Group, Techstars Ventures) and the eventual Webscale acquisition.
