Tri-Go Math

Hobby project in development since 2020. Bilingual math platform built as a Next.js 16 web app with 26 schema-driven API calculators, a custom 2D graphing engine, and an AI math assistant with streaming chat (Vercel AI SDK). The mobile app is a Flutter shell with native UI components — SwiftUI on iOS and Jetpack Compose on Android — connected via platform method channels. Calculators and chat are embedded as WebViews from the web app, while navigation, glass-morphism effects, and bottom sheets are rendered natively. Stack: React 19, TypeScript, Tailwind CSS v4, Prisma + NeonDB, Clerk auth with rate limiting, Riverpod state management, and Fastlane for deployment. 100K+ downloads across iOS and Android.
