Senior🎓
Top SchoolDave Collier-brown is a systems-focused engineer and author with 15 years of hands-on experience building and tuning high-performance platforms, having led Sun Microsystems Canada’s performance team and later driven platform and operations work at Index Exchange, Rakuten Kobo, and other firms. He specializes in capacity planning, migration engineering and low-latency production systems—work that supported real-time ad auctions and large-scale content platforms. Now writing a pragmatic book on application performance using queue-based mechanical models, he translates deep systems knowledge into accessible explanations rather than heavy math. Based in Old Toronto, he blends seasoned consulting and in-house engineering perspectives, with a background that uniquely pairs performance debugging at major enterprises with product- and ops-oriented delivery.
