Notes · curated

AI · Tech · Crypto · Science · Geopolitics

This is where the topics I'm seriously working on land: AI models and agent tooling, self-built stacks for crypto research and smart home, selected science and geopolitics reading. What you'll find here: curated news with source, personal projects with honest status, compact cheatsheets to take with you — no sales pitch, no financial advice.

  • News with source. Links, not an algorithmic feed.
  • Projects with status. What runs, what's alpha, what's back in the drawer.
  • Cheatsheets to take with you. View or download.

About me.

Rafael Stefanik in profile, Berlin skyline with TV tower in background

Hi, I'm Rafael — married, two kids, based in Berlin, languages German · English · Polish. DevOps engineer by profession; what runs on this site is a private hobby — AI, self-hosting, my own stacks.

Career switcher who wrote his first program on a Commodore at age eleven, later came into IT through retail, Amazon FBA with self-built C# software, and web development. Home-server rack in the office, self-hosting first, local stacks before someone else's cloud.
