Selected work

I build human-centered products where AI and new media meet the experience industries — travel, leisure, and wellbeing. Technology should make real experiences warmer, not colder.

Selected Work

Circadian science · Travel · Wellbeing

chrono-compass

Simulates your body clock with a published limit-cycle model, then computes the fastest day-by-day light-and-dark schedule to beat jet lag. Gated on biological unit tests — travel and wellbeing, taken seriously as science.

Algorithms · Travel · Operations research

route-compass

Solves the Team Orienteering Problem with Time Windows — an NP-hard multi-day itinerary optimizer (greedy insertion + iterated local search), hand-written and running entirely in the browser. The hard-algorithms flagship in this portfolio: travel meets real operations research.

AI · Travel · BYO-key

trip-compass

An AI itinerary planner that talks straight to Claude or OpenAI with your own key — no middleman server. The clearest proof of AI × travel in this portfolio.

AI · Embodied agents

minecraft-ai-bot

An AI-driven agent that perceives and acts inside a living virtual world — a sandbox for how agents behave in immersive, playful spaces.

New media · Tourism · Web

China Landscapes

A new-media showcase of China’s natural landscapes — digital storytelling for destinations and travel.

Product · Web · Engineering

fire-compass

An inflation-aware financial-independence calculator — privacy-first, zero-dependency, unit-tested. Proof I ship polished, trustworthy products end to end.

Product · Finance · Data-viz

dca-compass

Backtests dollar-cost averaging vs lump-sum on real index history — bundled data, money-weighted IRR, unit-tested. Another polished, end-to-end product.

Product · Privacy · Family tools

mingbai

A self-serve organizer for after-death digital affairs in China — inventory scattered WeChat, Alipay, game and cloud-photo assets into a list your family can find and understand, paired with per-platform how-to guides. No password fields, zero network requests, and explicitly not a will — property division still goes through a notary.

AI engineering · Open methodology

skill-forge

A closed-loop pipeline for hardening AI skills — a cheap model mass-generates adversarial evals, a capable model surgically tunes, and curated scenarios become a public eval set. The engineering rigor behind the products above.

Also More “compass” tools — longevity-compass (retirement Monte Carlo), calm-compass (guided breathing) and jetlag-compass — plus generative experiments (strange-equilibria) and assorted web pieces. See all on GitHub ↗.

How I work

01 / Human
People first
Technology should warm real-world experiences — travel, leisure, health — not replace them.
02 / Design
Form follows function
Every element earns its place. Restraint over decoration; clarity over cleverness.
03 / Quality
It just works
Reproducible, tested, private by default — made to outlast the hype cycle.
04 / Open
Yours to keep
MIT-licensed and offline-capable. Fork it, run it forever, make it your own.
