My name is John McCall and I specialize in reliability engineering, incident management, DevOps practices, and database systems. I’ve worked at organizations ranging from the largest companies in the world to startups with less than 100 employees.
As a chronic optimizer and problem solver, I don’t shy away from complex troubleshooting or the persistence required to make systems run smoothly. Whether I’m contributing to open source projects like my DBA MultiTool or responding to incidents (thanks, PagerDuty), I’m focused on building reliable, maintainable systems.
If you need help, I can promise persistence, a positive attitude, and practical solutions to your reliability and performance challenges. You’ll have direct access to all of my knowledge and experience across incident response, automation, and infrastructure.
