01 / The server

A domain that does work.

This stopped being a portfolio a long time ago.

Ryder Katz — CS & Psychology at Saint Louis University ('27), making music as TLR.

ryderkatz.com is the machine I run my life and work through. It has three layers: a public front (the apps, the research, the music), a private Portal — dashboard, agent console, and workspaces for everything from places and expenses to school and the studio — and an agent layer: an API with an MCP connector, so language-model agents read, write, and build here alongside me. Everything ships the moment it's committed.

◍ PUBLIC
The front
Apps, research instruments, and the TLR catalog — the parts of the server anyone can walk into.

▣ PRIVATE
The Portal
The admin half: a widget dashboard, an agent console, and workspaces — places, expenses, calendar, shopping, school, md vault, software, keychain.

❯_ AGENTS
The agent layer
A FastAPI backend with an MCP connector — agents query and maintain the same data the Portal shows, and every deploy is one push away.

02 / Launcher

Every live app, right here.

The same drawer that lives in the nav — nothing curated, nothing stale.

03 / Research

Three fields, three instruments.

Research here means tools you can operate, not papers.

◈ LIVE
The Comorbidity Atlas
The psychology field's core instrument — a queryable substrate of 15 conditions, 34 mechanisms, and 278 cited edges covering masking, amplification, and the cases where two labels describe one process.

✳ LIVE
The CS Taxonomy
The home field as one structure — ten domains unfolding into fields and topics on a single polar map, where angle is meaning, radius is depth, and everything expands outward with precision.
