Kayleigh Rex
Solutions Engineer
Kayleigh Rex is a Solutions Engineer at Embrace and a veteran of teaching dinosaurs to figure skate. A decade in DevOps and digital transformation has taught her that error-focused observability is blind to the user experience. Your stack can be flawless and your users will still one-star your app if it feels like wading through treacle. She writes about OpenTelemetry, mobile observability, and the things backend teams confidently believe about monitoring front-end and mobile apps but probably shouldn't. When she's not assassinating technical and cultural bottlenecks, she skates for Team Scotland's roller derby squad, fresh off the 2025 World Cup.
The golden signals are not wrong, but they only tell you server-side health. You need user-focused observability to tell you whether users are succeeding.
