Hi, I'm Han Qiao 👋

📍 Singapore | 🐘 Backend Branching @ Supabase | 🧪 Postgres + agents

Building Postgres-native infrastructure: agent harnesses, media processing, and remote execution — all inside the database.

Start Here

• 🌍 OpenWorld - Postgres-resident agent harness for world, language, and vision models
• 🔌 supabase/mcp (2.9k+ stars) - connect Supabase to your AI assistants
• 🖥️ supabase/cli (2.4k+ stars) - manage migrations, edge functions, and local Supabase
• 📸 pg_bager - inline PNG/GIF in psql results
• 🎞️ pg_ffmpeg - FFmpeg media processing inside Postgres
• 🔐 pg_ssh - run remote commands over SSH from inside Postgres

Current Projects

Agent Harness

• 🌍 OpenWorld - multiplayer agents in group chats; every turn runs as a durable Postgres workflow with replayable message rows

Postgres Extensions

• 🔐 pg_ssh - one-shot exec, key generation, and pooled SSH transports from inside the database
• 🎞️ pg_ffmpeg - media_info, thumbnail, and transcode for bytea media, built with pgrx
• 📸 pg_bager - a narrow psql pager filter that renders image-shaped bytea inline (Kitty, iTerm2, Sixel)

Local Models

• 🧠 .llm - config files for running models locally (llama.cpp + opencode, Qwen on 16GB VRAM)

Older Projects

• 🔑 streamlit-supabase-auth (60+ stars) - Streamlit login forms backed by Supabase OAuth
• 🎭 text-to-anime - convert text and audio to facial expressions
