About the Cook

I first got to work at 15 flipping hash browns at Waffle House in the wee hours of the morning. That's where I learned the fundamentals that still drive me today: stay calm under pressure, keep the systems running, and never make the customer wait.

Lately, I circuit-break code instead of breaking the grill. As a Senior Site Reliability Engineer, I bring that same 24/7 WaHo mentality to keeping production systems healthy, automating away toil, and making sure incidents get resolved before they become the customer's problem.

Just like in a well-run kitchen, software should be highly observable internally and look effortless from the outside. My job is to make sure the customers never see the waffles burning behind the scenes.
