About
I'm a Cloud & DevOps engineer who keeps large-scale systems fast, resilient, and observable. When I'm not moving mountains (or at least, data) to the cloud, I'm tinkering with on-prem setups — someone has to keep those ancient relics running, right? Today I work on reliability, automation, and observability as an SRE at Mastercard.
