👋🏾
My name is Xavier, and this is my corner of the web.
I’m a husband, dad, and DevSecOps engineer. When I’m not working, you’ll usually find me tinkering in my home lab or jogging around Philadelphia.
I write about what I’m currently learning—both to share knowledge and to solidify my own understanding.
