I build software for systems that shouldn't be this bad. Right now that means aviation — tens of thousands of flights operate daily on infrastructure designed in the '90s. Nobody with both software taste and domain knowledge has seriously tried to fix it.

Building Air-OS: one operating system for aviation operations. Data fusion, prediction, simulation, and coordination in a single loop so operators act in seconds, not minutes.

Before

UC Berkeley CS/ML '23. Published at ICLR on Chatbot Arena / LM Arena (now used industry-wide for LLM evaluation). Shipped production systems at Apple and Hive AI.

The connecting thread: I keep finding critical systems running on software that doesn't respect the people who depend on it.

LiveTerm

5,400+ stars

Terminal-style website builder. Weekend experiment, no business plan — turns out developers wanted portfolio sites that respect the terminal.

LetsMarkdown

825+ stars

Real-time collaborative markdown. Built it because existing editors were too heavy or didn't sync well. Rust WebSocket backend.

Bionify

273+ stars

Chrome extension — bionic reading for any webpage. The idea that typography changes comprehension speed felt underexplored.

Macoustic

54 e2e tests

Laptop lid angle as a musical instrument with cymatics visualization. Lid motion → sound → physical waveform patterns.
