I build AI that writes01, narrates02, and invests03.

Three production pipelines — each shipping a finished, rigorous, real artifact: a writing editor that rebuilds voice, a storybook engine that narrates and illustrates, and an investment system that enforces discipline. Former engineering director who led 50+ engineers; full-stack to multi-agent AI.

Selected work

Each system ships a proof artifact you can open — not a pitch.

01Narrated storybook engine

Fairytale Engine

An end-to-end pipeline that turns a story idea into a narrated, illustrated children's book — script, voice, illustration, mixed audio.

Pipeline
Script → voice → illustration → mixed audio
Continuity
Per-character visual manifests — no drift across plates
Output
KDP-ready EPUB · narrated read-along
Hear it & see the book
Plate · illustration Rocco & the Trail to the Top

02Decision-support system

Investment Pipeline

A staged decision engine that encodes a personal investing discipline — macro → technicals → valuation → risk — into a structured, redaction-verified report.

Gates
7 staged gates · 37 encoded decision rules
Discipline
Backtested thresholds · versioned releases

AI draft

In today's fast-paced world, it is crucial to delve into the multifaceted tapestry of one's thoughts.

Li's voice — rebuilt

I keep one true sentence and cut the rest. The reader feels the difference before they can name it.

§ 04

How I work

One belief, applied three ways.

Engineer who writes. Investor who builds.

The three projects aren't unrelated demos — they're one belief, applied three ways: AI is most useful when it carries judgment and craft all the way to a finished artifact.

More about me →
A

Proof over pitch

Every project ships an artifact you can open — a voice diff, a narrated book, a redacted report — instead of a deck about one.

B

Verify ruthlessly

Prompts are treated like software: fixed corpora, deterministic checks, and an independent cross-model judge. "It works" is measured, not asserted.

C

Judgment as a system

A value-investor's discipline applied to engineering — encode the rules, stage the gates, and let the structured output carry the call.
