Cherry
Voice-of-customer triage.
BUILDClaude via the Anthropic API, searching the open web — reviews, forums, Reddit, news. Feedback flows browser → backend → Claude; nothing stored.
LOGICClusters raw feedback into issues, then ranks by a weighted signal — severity, then reach, then recency. Your corrections re-rank it.

offramp
Personal finance, debriefed.
BUILDStatic HTML and JS — the parser, the stats, and the whole rules engine run in the browser; no server, no account, no dependencies. Optional second opinion through the Anthropic API, on your own key, summary only.
LOGICAsks what you think you spend before it shows you a single number, then scores the gap. Makes claims about your habits with confidence attached, lets you grade them, and rewires its own thresholds from what it got wrong. Only then does it rank what to do next — impact × confidence ÷ effort.

Loop
The org-wide feedback loop, as a product.
BUILDInteractive product prototype — one self-contained web app · designed and built with Claude · editorial UI · CVD-validated chart palette.
LOGICNine channels (support, field, early access, in-product) → one system of record. Seven personalized role views, from support triage to a 90-second exec brief. Praise travels the same pipes as complaints; every closed loop ends in 'you asked, we shipped.' Guided demo story + phased scale plan built in.

Portraits
Live data storytelling.
BUILDNext.js + Framer Motion, drawing on live public feeds — NASA, USGS, NOAA, NYISO, Citi Bike, the NWS — proxied server-side with caching and graceful fallbacks. Real coastlines, charts, and gauges hand-built in SVG; no database, no keys.
LOGICOne page, three portraits at three scales: the world this second, a single human life, a city over a day. Every square is a true number, live — click one to fall into the story behind it.

Henry
Amazon 1P vendor operations.
BUILDNext.js + Claude with web-search tool use, server-side. Agentic tool-calling for chat and research; deterministic code for the financial math.
LOGICTrue net PPM per ASIN (co-op, freight, chargebacks, returns, ads); classifies chargebacks by root cause and drafts the dispute. Graded by evals.

Stanley
Calendar agent.
BUILDGoogle Calendar read/write, over Telegram with voice. The write is gated in code, not the model.
LOGICReads the week's schedule and proposes one-line fixes; never acts without confirmation. Learns preferences as seasonal probabilities.

Eluna
Memory architecture.
BUILDClaude with a persistent memory layer — summarizes on a cadence and on exit; lighter models handle summarization.
LOGICRanks what to keep by importance and recency; a light root persona, values over rules.
