I'm a builder, engineer, and developer. I like turning fuzzy ideas into working systems: AI agents, developer tools, infrastructure, and small utilities that make daily engineering feel lighter.
- tiny-rag-lab - a learning-first RAG engine for classic RAG scenarios.
- tiny-duo-infer - A learning-first LLM inference engine built from scratch in Python and MLX, with a local OpenAI-compatible Chat Completions API.
- tiny-gpt - built GPT from scratch through hands-on ML practice.
- neetcode-submissions - algorithm and ML practice notes from NeetCode.
- human-in-loop-workflow - a simple, well-behaved workflow for human-reviewed agent work.
- zot - a lightweight Go coding-agent harness fork where I contributed session behavior fixes upstream.
- zot-goal - a TypeScript extension for goal-oriented agent runs.
- holon - a local workbench for agents doing continuous work across sessions and commands.
- Rewritr - a native macOS app that rewrites English into more natural, native-like text using your own OpenAI-compatible provider.
- Porta - a native macOS app for finding and killing orphan listening ports.
- climb-coach - a climbing coach app and a personal gift project.
- Windows_Hotkey - useful scripts and hotkeys for working on Windows.
- zmopenapi-sdk-golang - a Go SDK for ZhiMa Credit integration.
- go-gridfs-serve - a HTTP server for serving files stored in MongoDB GridFS.
- neo4j-plugin and neo4j-kernel-extension - Neo4j plugins and extensions.
