a life well lived comes down to two daily acts: build something your future self will thank you for. feel something your present self will miss when it's gone.

hi. i'm justin.

i make many-part things run as one thing. that has been the whole job since i was seventeen, at a fire department on long island where the parts were men and trucks, and it is still the job now that the parts are companies. the résumé is downstream of that sentence. it lives further down this page, where it belongs.

by day i run the operating system inside an agentic data company, meaning everything the org chart does not show and everyone assumes someone else is doing. it keeps me sharp. after hours it gets harder to file. there is a sleep brand that is secretly a longevity play. there is a company that believes in exactly one molecule. there is a public person whose deal flow i look after, a market book i run with a council of machines whose opinions i keep score on, and a second brain that at this point knows me better than i do and has started to say so.

the method is less elegant than the pattern. a heat-seeking missile for pain: you find the one thing that is rate-limiting, you make it disappear, and then you find the next one, and you do this until the thing runs itself, at which point it doesn't need me, and i take that personally, and i leave. i have come to enjoy it. bring me the weird ones.

off the clock: calisthenics, skeet, climbing things, racing cars, and, before any of that, five years on a volunteer fire truck. on the fun scale below i aim for type two and am regularly promoted to type three, which is not fun during and not fun after and makes a story you can dine on for years. the most recent promotion: two reps short of the world record for pull-ups off a helicopter, and then jiu jitsu at three in the morning, which took the elbow. the elbow is recovering. the record is not going anywhere.

the receipts, since you scrolled: taiwanese american. long island, taipei for middle school, long island again, then vanderbilt, which issued a very handsome piece of paper that lives in a drawer. since then, interesting problems with interesting people. that is the whole résumé. the rest is detail.

these notes are more for me than for you, but walk around. the underlined parts open. if you arrived here through someone we both know, that is the correct way in, and the email is at the bottom.
