the maker
I'm Henry.
Fourteen, from Austin, and a proud vibecoder. I build voice AI, robots, a submarine, and a company. I go to Alpha High School. Right now I work at Crawft, and I founded SiteLight.

current job
Crawft
I'm cofounder and CTO, since mid-August 2026. Crawft is an AI-powered monitoring tool for schools and managers: it turns activity data into answers backed by evidence, and sends smart nudges that steer people off bad websites.

cybersecurity
Vurn AI
A fully autonomous AI pentesting tool. 24 hours after I built it, it found a major vulnerability in a top-200 GitHub repo that gave access to over 40,000 Shopify accounts.
founder
SiteLight
A personal challenge: go from nothing to revenue in under two weeks. I made it in 10 days. It checks whether AI assistants recommend your business when someone asks, then hands you the to-do list to become the answer.

voice AI
Lily
Calls my grandma every morning, has an actual conversation, then texts the family how she sounded.

Glasscast
Screen Studio costs money, so I made a free one. Cinematic zooms, auto-captions, a webcam bubble, bring your own AI keys.

design
This site
My portfolio, designed from scratch. Behind the page is a koi pond drawn in ASCII tiles: black and white koi, little fish that scatter from your cursor, and wakes that light up where they swim. Rest the cursor and the koi come to look, and tiles flip over as you pass across them. The koi follow your cursor, and a click calls them over to that spot. My name decodes into the pond tile by tile. Black and white only.

voice AI
Lily's Drive-Thru
Order out loud. The AI takes it, upsells you once, reads the total back with tax, and fires a live ticket to the kitchen screen.
Repo ↗
AI + audio
Eleven Mile
Pick two people and a topic and watch them rap-battle. Claude writes the bars, ElevenLabs raps them. A little dumb and I love it.
Repo ↗
accessibility
PawBot
Helps older people use a computer one step at a time, like helping your grandparent figure out their email.
Repo ↗
robotics
S.I.E.G.E.
A self-driving car that chases my dogs around while I'm busy. Sensors, steering logic, a lot of calibration, and wiring that looks worse than it works.
hardware · building now
ROV Submarine
A remote-controlled sub that has to survive real water. Most of the work is the unglamorous part: watertight, buoyant, and a battery that behaves.

Open source
Real, merged pull requests to tools I use: SymPy, Biome, Astro. Small fixes, shipped, and people actually run them.
