Isaiah Kim — Staff Engineer · 0-to-1 Product Builder · NYC

Staff engineer & 0-to-1 product builder — I use AI leverage to do what normally takes a team.


TypeScript Next.js 16 React 19 Tailwind v4 Turborepo Supabase Stripe Claude Vercel

What I'm building

Kynth Studios — a one-person AI product studio. I built the platform that makes shipping production software cheap: a shared design system, a multi-tenant production spine, and an automated demo pipeline that take an AI product from design → engineering → infra → launch, solo.

  • 9 marketed wedge apps that get small businesses paid — invoicing, chargeback recovery, payment recovery, legal billing, AI reception, no-shows, CRM cleanup, win-back — all running on one multi-tenant spine (72 tenants live on a single wildcard, 9 marketed).
  • Kynth Core — the same engine as a developer platform: 39 pay-per-call API endpoints with TypeScript / Python SDKs, an MCP server, and n8n / Zapier / CrewAI connectors.
  • A self-built content pipeline (Playwright + Remotion + ElevenLabs) that auto-produces narrated product demos — 31 published so far.

FetchDue — the collections agent for agencies. An AI agent that chases overdue invoices end-to-end: it sends the chase from the agency's own mailbox, reads the client's reply, negotiates a payment plan within the agency's rules, captures the commitment, and takes the payment. A standalone vertical product forked from the Kynth invoicing spine.

The studio is early — I'm selling the leverage I've built, not a user count. The catalog is the proof that one engineer can ship at studio scale.
