How I Build

Privacy First

I believe in building software that respects user agency. No tracking pixels, no invasive analytics, just pure functionality.

Self-Hosted First

Empowering users to own their infrastructure. My solutions are designed to be deployable anywhere, from a Raspberry Pi to a Kubernetes cluster.

Open Source Friendly

Collaboration fuels innovation. I actively contribute to the ecosystem and build with transparency at the core.
