Bruno Del Castillo
Finance student at NYU Stern, graduating in 2027. Spent this past summer in private equity at Goldman Sachs.
I want to be the operator founders hand the messy, unglamorous problems to, and the one who makes them work.
I learned business watching my grandparents sell produce from their farm at a local market. Grew up between Korea and Dallas, now in New York. These days I'm curious about consumer health, human performance, and hospitality, and I'm usually training for my next HYROX.
In NYC. Part-time now, full-time from Feb 2027
Projects tap to open
-
A health coach that lives in a text thread. Text it what you ate (or a photo of the plate), how you slept, what you're taking, and it logs it, remembers it, and checks in every morning. One short reply, no app to open.
I built it because health and performance is what I actually care about, and the best interface is the one you already use all day.
-
One profile of me, filled into any app signup or job application. Claude reads the form, maps each question to my profile, fills what it can, and stops before passwords, payments, terms and the submit button. Those stay mine.
It started after testing a friend's supplement app with a long onboarding. Before building, I mapped what 10 health apps ask: 80 questions that collapse into 35 fields.
-
Claude Code set up to run my week. It knows my projects, the people I'm talking to, and how I write, and it keeps its own memory as things change. It researches companies, drafts outreach, preps interviews, plans trips into Notion and keeps my files in order.
Rule one: it drafts, I send.
-
Designed and built in a single Claude Code session. One HTML file, no framework.
