About

Hey there, I’m Toni! I’m a Security Engineer and a tech enthusiast from Finland. Currently, I’m working as a Security Engineer at Wolt, where I focus on security operations and incident response.

In my free time, I enjoy working on various personal projects, from building and experimenting in my homelab, to developing custom tools like my SIEM / SOAR Vanguard. Beyond tech, I enjoy hiking and spending time in nature, as well as “working” as a volunteer firefighter.
