🛠️ What I've Shipped

The AI-powered operating system for startup founders. Think Notion + Linear + ChatGPT — purpose-built for founders who move fast.

  • AI Chief of Staff — GPT-4o streaming chat hydrated with full project context: tasks, KPIs, competitors, experiments, and ranked founder memories
  • Founder Memory System — auto-captures decisions & pivots, ranks by relevance, injects top-10 into every AI prompt
  • Stripe Billing — 4-tier subscription enforced server-side with HMAC-verified webhooks

Next.js 16 TypeScript PostgreSQL GPT-4o OpenRouter Stripe Zustand Zod Recharts


📝 AnchorLive App

Notes that never disappear. Every keystroke saved locally first via Yjs CRDTs. Syncs across devices. Conflicts resolved automatically — no "pick a version" prompt. Ever.

  • Offline-first — browser is the database (IndexedDB). Works with zero network
  • CRDT sync — same conflict-free replication tech used by Figma and Notion
  • Stateless relay — y-websocket on Railway; cross-device sync with zero data loss

Next.js 16 Yjs Tiptap y-indexeddb y-websocket Dexie.js Tailwind


AI-powered web accessibility scanner that finds what automated tools miss. Dual-engine: axe-core rules + GPT-4o Vision. Scan to report in ~10 seconds.

  • 96% of top websites have WCAG failures — axe-core catches ~30–40%, GPT-4o Vision catches the rest
  • Actionable fix suggestions — not just "this is broken", but here's the exact code fix
  • Auth-gated deep scans via Clerk + persistent history via Neon + Drizzle ORM
