Selected product & systems work
The work below spans a live role-playing game, an auditable research system, and trading operations. Each case starts with the thing a person actually sees, then opens the machinery that keeps state, evidence, and human decisions intact.

Selected systemsAI-native product · Live operations
Choose a world. Act freely. Live with what it remembers.
A live multi-world text RPG where choices change relationships, abilities, and later scenes instead of disappearing after one model response.
Founded and built with a two-person team.
Agentic financial research · Evidence integrity
Before a draft leaves the system, it must show where every material claim came from.
Kairosys coordinates specialist research, keeps source, period, and unit attached to each claim, and stops weak drafts before a human analyst receives them.
Designed and built solo by Titus Lai.
Agent operations · External side effects
The order closed. The position did not.
A long-running trading-operations system built around the moment a local ledger says closed while the exchange still says open—and the recovery path that follows.
Created and operated by Titus Lai.
