Mathias Graf from Switzerland. diisi is a childhood nickname — what my little sister called me when she couldn't pronounce my name yet.
I build digital products that solve real problems. Currently running 4 projects in the Swiss market — from playgroup management to insurance comparison. All self-hosted on my own infrastructure.
Open source projects and code. Mainly Astro, TypeScript, Bun, and Docker. Currently 4 active projects on a Hetzner VPS with infrastructure as code.
