Students across Boston's campuses buy, sell, and sublet through chaotic group chats and public marketplaces full of scams — with no student-verified, campus-specific alternative.

A working platform built with Claude: a live Supabase backend with real account creation and email confirmation, a .edu gate enforced at the database level, listings with search, categories, and favorites, sublets with dates and rent, photo uploads, and buyer-seller chat. Alongside it: a business plan with a 7.5% transaction fee benchmarked against Poshmark (20%), OfferUp (12.9%), and Mercari (10%), a 3-year revenue model, and a 10-week zero-budget launch plan built around move-in season. It's pre-launch — getting the first listings live is next.

Social life forces a choice — you're either the wellness one or the party one, the early-morning workout or the late-night out. No community brand owns the overlap for people who are unapologetically both.

Duality is a community for people who are both — the one who works out and the one who dances all night — and shouldn't have to choose. We bring them together through "coffee raves" and events across Miami and Boston: spaces where wellness and nightlife live in the same room, with the same people. Sweat all day, dance all night. The whole point is to own the overlap most social scenes make you pick between, and build a real community around being both. We're launching soon, with our first event in the works.

My health data lived in silos — Oura for sleep and recovery, a separate plan for running, scattered notes for everything else. Nothing pulled it together to tell me, in one glance, whether I'm actually getting fitter or just staying busy.

A single-page dashboard built with Claude and wired to my own Oura ring: I built the Oura API integration myself — a Cloudflare Worker that calls the API and relays my sleep score, readiness, HRV, resting heart rate, steps, calories, and workouts into the app automatically each day. It turns that data into a "% to superhuman" progress ring across health pillars, a "where to focus" read on my last 7 days, a half-marathon training plan with a race countdown, and training-science metrics like acute-to-chronic load ratio and fitness / fatigue / form. It's live, and I use it every day.
