Martin Walsh, MD
A surgeon who ships software.
General surgery resident on a cardiothoracic track. I design and build real tools — iOS apps my co-residents use, surgical-AI research, and a self-hosted personal AI system. This is the index.
Clinical & Health
04Software for the work itself — the clinic, the OR, the body.
DutyTracker
★Automated ACGME duty-hour logging for residents.
CasePrep
★Surgical case prep built from your own operative notes.
Spotter
An autoregulating workout app for the time-starved.
Step 3 Deck
A self-contained spaced-repetition deck for board prep.
Research
02Computer vision and technique, scoped to teaching.
AI Systems
01A personal operating system — voice-first, self-hosted, always on.
The most ambitious build here — and the one I lean on most. Shown at the level of what it does and how it's put together; the private details stay private.
Creative & Maker
03What gets built for the love of building.
I'm a general surgery resident on a cardiothoracic track. Between cases, I design and build software — most of it because I needed it and couldn't find it: a way to log duty hours without the friction, a way to walk into an operation prepared from my own notes, a system to keep the rest of life moving on an unpredictable schedule.
The throughline across everything here is the instinct I bring to the OR: remove friction, never remove judgment. These tools detect, draft, and surface — then they wait for a human to decide. I ship them, use them daily, and keep iterating.
