Medium bio
Ranjib Dey is a software engineer working on production engineering and reliability at Uber. His public work spans infrastructure as code, testing discipline for operations, Linux containers, service discovery, incident management, resiliency engineering, and ML-assisted capacity management. He was an open source maintainer of Chef, received the Chef Awesome Community Member / MVP award, authored chef-lxc, and has presented at venues including ChefConf, LinuxCon, Agile 2015, HashiCorp User Group SF, ChaosConf, and the Major Incident Management Expo. He also builds reef-pi, an open source Raspberry Pi based reef tank controller recognized by Maker Faire and covered by Make:, Adafruit, and the Raspberry Pi Foundation.
Longer bio
Ranjib Dey is a software engineer focused on production engineering, reliability, platform engineering, and open source systems. His public career arc starts with Chef, infrastructure as code, and testing infrastructure code; continues through TDD in operations, CI/CD for Chef, LXC, and Consul at PagerDuty; and extends into hyperscale production engineering at Uber through public work on ML-driven capacity safety, incident taxonomy, incident management, and failover architecture.
He was an open source maintainer of Chef, received the Chef Awesome Community Member / MVP award, authored chef-lxc, and has published or presented work at FudCon, vodQA, DevopsDays India, ChefConf, LinuxCon North America, Agile 2015, HashiCorp User Group SF, ChaosConf, Major Incident Management Expo, Uber Engineering Blog, and USENIX NSDI 2026. Outside work, he builds reef-pi, an open source Raspberry Pi based reef tank controller with public documentation, hardware ecosystem, community support, Maker Faire recognition, and coverage from Make:, Adafruit, and the Raspberry Pi Foundation.
Project blurb: reef-pi
reef-pi is an open source Raspberry Pi based reef tank controller. It automates reef-keeping modules including equipment control, temperature, lighting, water level, pH monitoring, dosing, telemetry, dashboards, and macros. The project grew into a public ecosystem with official guides, GitHub repositories, Reef2Reef community support, compatible hardware paths, Maker Faire recognition, and coverage from Make:, Adafruit, and the Raspberry Pi Foundation.
Project blurb: Chef and infrastructure automation
Ranjib’s public Chef work includes Chef maintainer activity, the Chef Awesome Community Member / MVP award, chef-lxc, and a sequence of talks and writing on system automation, infrastructure testing, dynamic infrastructure mocking, TDD in operations, and CI/CD for Chef and LXC. The recurring theme is treating infrastructure changes as software changes: versioned, reviewed, tested, and continuously delivered.
