Community Leadership

Managing my building condominium isn't just about maintenance—it's about applying the same pragmatic leadership and conflict resolution I use in tech to my real-world community.

The Tinkerer's Mindset

My "homelab" isn't a museum; it's a sandbox. It's where I break things to understand how they work, from self-hosted automation to experimental networking protocols.
