01About

Hey there, I'm Henry! I'm passionate about using tech for societal impact, climate change, strategy games, and philosophy. Take a look around at what I've done and what I'm working on

I study Computer Science and Philosophy at Brown. Before that I spent four years at Phillips Academy Andover as a Caroline D. Bradley Scholar.

In 2026, I was a founding engineer at Asteria Labs in San Francisco, building AI video avatars and leading go-to-market. My research has ranged from decarbonization pathways at the MIT Energy Initiative to neural networks for syllogistic reasoning at Cambridge, with four papers and presentations along the way.

Outside of school and work, I play tournament chess as a USCF National Master, run sprints and long jump, play piano, and beatbox.

Things I've made.

Selected work, newest first. Each one links to the code and, where it exists, a live deployment.

Hackathon winner · Full-stack

FitCheck

Winner of Columbia DivHacks 2026 (Live Better track). Scan a small NYC room once, text furniture ideas over iMessage, and rearrange your real room like a top-down game before you buy or haul anything up three flights of stairs.

Challenge · Making the whole stack demoable offline: the FastAPI backend and Vite editor run in a mock mode with zero env vars, then switch to Supabase and the iMessage relay when real keys are present.

Developer tools · AI agents

Threadline

A chat-first workspace for building software with coding agents. An orchestrator model deploys isolated agent runs, verifies their output, and integrates accepted code, while the conversation itself is a tree: open decisions fork into labeled directions you can revisit.

Challenge · Two compatible runtimes from one codebase: hosted on Vercel with Postgres and persistent sandboxes, or fully local with SQLite and detached Git worktrees.

Vercel Sandbox

Systems in the browser

Mini Desktop

A local-first desktop that lives entirely in your browser: draggable windows, a virtual filesystem, and eleven working apps that share live file state, with no backend or accounts. Reload or open a second tab and everything is still there.

Challenge · Durability without a server: files, notes, and events live in IndexedDB behind a serialized write queue, with a pagehide journal so writes survive instant navigation.

IndexedDB

Data product · Sports

FF Dash

A personal ESPN fantasy football dashboard and predictor. Blends projections from ESPN, Sleeper, and a rules-based model into a consensus that powers a lineup optimizer, matchup preview, waiver finder, and trade analyzer.

Challenge · A season-long accuracy tracker re-tunes the consensus weights from what actually happened each week, driven by a daily Vercel cron.

Machine learning · Python

fpl-predict

Predicts a Fantasy Premier League player's points for the next gameweek. Live scrape of the FPL API, Understat, and historical archives, joined into leak-safe features for a gradient-boosted model with time-based validation against baselines.

Challenge · Honest evaluation: expanding-origin folds that hold out the final stretch of each of the past three seasons, reported as WAPE accuracy over single and three-gameweek windows.

Game · Three.js

The Snap League

A compact browser arena shooter with articulated toy-like rivals, six multi-floor campaign arenas, generated audio, radar, and a complete three-minute match loop, ending in a multi-phase boss fight.

Challenge · A per-arena adaptive director that targets a 20% win rate by tuning bot reaction, movement, and accuracy from recent local results.

Social · Recommendation

Kindred

A swipe app for genuine platonic connection: one deck of people worth saying hi to, one deck of activities worth inviting them to. Every match ships with an icebreaker built from real shared ground and a 'plan something' button.

Challenge · One profile, two decks: people and activities share a single vocabulary of interests, connection factors, and vibe axes, so swiping on either sharpens the other.

Vite
Taste engine

Recommendation engine

Decluttered

One taste engine, five cravings: books, movies, TV, music, and restaurants. Swipe a ranked deck, rate what you consume down to individual craft elements, and browse a For You page built by seven labeled suggestion mechanisms.

Climate · PWA

GreenSite

A sustainability hub for real-estate developers: a portfolio dashboard, a US requirements tracker that matches federal, state, and local rules to each project's location, a LEED v4 scorecard, and an interactive embodied-carbon visualizer.

Research · Statistics

Kalshi vs. Sportsbook NBA Pricing

A Python data pipeline and statistical analysis comparing NBA game pricing on Kalshi, a regulated prediction market, with aggregated sportsbook odds. Final artifact for CSC600 at Phillips Academy Andover, with Justin Puno.

Challenge · Working around a data gap honestly: Kalshi's API does not expose pre-game closing prices, which shaped both the method and the paper's stated limitations.
