A spreadsheet, replaced
AlphaInvestor
Portfolio tracking · iOS
People holding positions across several brokers were maintaining a spreadsheet by hand to see one number: what they actually own. It went stale the moment a price moved. Now it updates itself, explains what changed, and flags what needs attention. An Expo iOS client, a Next.js API on Vercel, Supabase for data, Sentry for errors — with a scripted full-session load test run before infrastructure changes ship.
Release pending

One number, always current 
What changed, in plain language
