About

Operator's judgment.
Investor's rigor.

I'm Li — a software architect and AI-systems builder in Fairfax, Virginia. I lead with what I can ship: real, multi-agent systems that write, narrate, and support investment decisions.

I spent years as an engineering director leading 50+ engineers, with a full-stack background across Java, Android, and Python automation. Today I build production AI pipelines and orchestrate LLMs into systems that do durable work.

I think like a value investor: build slowly, verify ruthlessly, and let the proof speak. I'm a lifelong learner and a bilingual writer — 中文 and English — on engineering, AI, and decision-making.

Role history

From leading teams to building systems.

Now

AI architect & independent builder

Self-directed · advisory

Design and ship multi-agent AI pipelines end-to-end — the editor, fairytale, and investment systems on this site. Advise teams on AI architecture and where automation actually pays off.

Engineering Director

Led 50+ engineers

Owned delivery across multiple teams — hiring, architecture, and the judgment calls that don't fit in a ticket. Learned that the hardest part of engineering is deciding what not to build.

Full-stack engineer

Java · Android · Python

Built and shipped across the stack — mobile, services, and the automation glue in between. The habits formed here — test it, measure it, version it — are the same ones in every pipeline I build now.

Philosophy

How I make decisions.

01

Proof over pitch

Every project here carries a working artifact, not a claim. If I can't show it, I haven't really built it yet.

02

Verify ruthlessly

Test-driven, with held-out evals and deterministic checks. "It seems to work" is where the real work starts, not ends.

03

Judgment as a system

Good decisions should be repeatable. I encode frameworks so the same discipline applies on a calm day and a loud one.

04

Keep the human

Whether it's a writer's voice or an investor's call, the system serves the person. The tool is loud; the judgment has to be louder.

Let's build
something real.
