By day, I work in SharePoint/Power Platform development.

For fun, I enjoy fiddling with my #aquarium, riding my #ebike, tinkering around with #HomeAssistant, playing #Factorio, going to #MetalShows, #Grilling, and reading about spaceships fighting.

Hello! I'm a random creature who has broken networking in production environments far too many times yet somehow still has access to lots of servers.

rather be 6 feet under than invisible, I want to be me, unconditionally :3
I guess roles I can be described as:
- gay creature
- self-managed hobbyist system administrator, opportunistic security researcher who gets bored quickly, networking girl, maybe programming enthusiast if I am in a good mental state and motivated
