Full-stack, agent & growth engineer. Co-founder & CEO of Celados — an AI-native product studio building for the agent era. Previously ByteDance (TikTok Live) and A1D.
I ship consumer AI products and the tooling that makes agents useful — across iOS, web, Cloudflare, and the Canva Marketplace.

| Project | What it is |
|---|---|
| ctx | Full-document search and reading for AI agents — finds curated library docs, searches the open web, and returns complete sources instead of RAG fragments. |
| gkit | Agent-first growth CLI — one profile-bound surface over DataForSEO, PostHog, Google Ads, Search Console, and Bing Webmaster, with offline capability discovery. |
Clonesite AI — turns any public website into an editable React + Tailwind
project. TanStack Start + Vite product app, Convex owning backend state and HTTP
handlers, and a generation worker producing clone artifacts. Built agent-first:
the Clone API ships as REST under /api/v1 and as a hosted Streamable HTTP MCP
endpoint at /mcp, with machine-readable discovery across /llms.txt,
/openapi.json, /.well-known/api-catalog, and /.well-known/mcp/catalog.json
— so an agent can find, authenticate to, and drive the product without a human
reading docs.
prism — local router daemon that puts agentic CLIs (Claude Code, Codex) on
third-party Anthropic/OpenAI-compatible endpoints. Binds 127.0.0.1, routes each
request by (inbound family prefix + body.model) to the right upstream, rewrites
only the URL, auth headers, and body.model, then streams the response straight
back. Deliberately not a protocol translator — each wire (anthropic,
openai-chat, openai-responses) is forwarded to an upstream that natively
speaks it, which keeps streaming and tool-call semantics intact. Rust; ships
prebuilt macOS arm64 / Linux musl binaries and a multi-arch Docker image, and
refuses to start on a non-loopback bind without an active API key so an exposed
port can never leak upstream credentials.
mcpx — turns registered MCP servers into an agent-friendly command surface.
Keeps registrations in a global user registry, discovers tool schemas, handles
OAuth where it can, and exposes each server as a root command
(mcpx posthog projects-get). Schema-first and explicit by design: tool input
goes through --input, while mcpx's own control commands stay namespaced under
@ so they can never collide with a server's tools. Bun, single-binary install.
A1D — Full-Stack Engineer · 2024-09 – 2026-05 · remote, US startup
Primary engineer across a consumer AI product line:
- RizzPlus / AI Dating Keyboard — iOS AI messaging assistant, Swift, built solo; still earning subscription revenue.
- Speed Painter for Canva — lead engineer on the Canva Marketplace app.
- Caption AI, ClosetCue AI, Wearly — AIGC web apps, built solo.
- Revival — Twitter growth automation. An MV3 extension (WXT + React) runs scheduled posts, AI-drafted replies, and engagement actions off a server-side task queue (Bun + Hono + oRPC, Inngest jobs), idempotent with backoff retries against rate limits and PostHog-instrumented throughout.
- Low-code email delivery on AWS SES + Cloudflare Workers + Lark base tables, ~80% cheaper to build and maintain than a conventional stack.
- Contributor to Lumina 3D (2D→3D generation) and the Grimo web product.
ByteDance — Software Engineer, TikTok Live · 2022-01 – 2024-01 · Beijing
- State machine managing UI logic across PK (live battle) stages — ~50% less code complexity.
- Multi-device log synchronization tool — ~60% faster troubleshooting.
- Feature iterations with cross-functional teams — ~25% lift in in-stream engagement.
