Callum Styan is a developer at Grafana Labs based in Vancouver, Canada, where he primarily focuses on working with Cortex and Prometheus, having joined the company after contributing to Prometheus independently. He has made significant contributions to open-source projects, notably rewriting Prometheus remote write to incorporate the Write Ahead Log and enhancing Cortex to support samples from High Availability Prometheus instances. With a background in data communications and network protocols, Callum has also worked on documenting the Android ADB protocol. In his leisure time, he enjoys reading fantasy novels, engaging in activities like leathercraft, and organizing the local Go meetup. Callum prefers listening to music or ambient noise while coding and treasures his Sennheiser HD650 headphones for this purpose. His favorite ice cream flavor is Swiss Orange Chocolate Chip from Elevated Ice Cream in his hometown of Port Townsend, Washington, and he recently binge-watched HBO's "Chernobyl."
