Lucas Frischeisen — code, characters and a little magic


✦ About Me

“I don't just develop software. I create characters, tools, and intelligent ecosystems.”

I build AI systems, developer tools, and software with personality — from agents with voice and memory to compilers and desktop experiences. I care about how software works, how it feels, and what we can actually verify.

I also produce electronic music as Reskyume/Rukafuu, follow anime and visual novels with a slightly unhealthy devotion, and believe personality is not technical debt.

    "agent systems",

  ],
  principle: "evidence before confidence",
  currentlyPlaying: "something magical and loud at 3 AM",
};
