I'm mingcheng (明城), an open-source practitioner originally from Ningbo and now based in Hangzhou, China. I enjoy building useful software and supporting the communities behind it.

I'm a senior software architect and open-source evangelist at Ant Group. Previously, I spent nearly a decade at NetEase as a senior technical lead and team manager.

My background is in cloud-native systems and software architecture, with a recent focus on AI agents and infrastructure. I value clean design, reliable automation, and turning ideas into practical, dependable systems.

I've used Linux for many years. NixOS is my daily driver, and I prefer Debian for servers. I also use macOS for development and testing.

I serve on a Project Management Committee (PMC) at the Apache Software Foundation and help maintain CNCF graduated projects. Some of the projects I'm involved in include:

• inclusionAI — Open-source AI models and systems (GitHub · Hugging Face).
• AReaL — Reinforcement learning infrastructure for foundation models and AI agents; listed in the PyTorch Foundation landscape.
• Dragonfly — P2P-based data distribution; a CNCF graduated project.
• Apache GeaFlow — Distributed graph computing for stream and batch processing; an Apache incubating project.
• Apache Answer — A community Q&A platform for sharing knowledge; an Apache top-level project.

In my spare time, I build and maintain small tools for everyday development and terminal use:

• aigitcommit — A Conventional Commit message generator using OpenAI-compatible APIs.
• mp3blstr — A terminal music player inspired by mp3blaster.
• simplyddns — A dynamic DNS updater with configurable IP sources and DNS providers.
• socks5lb — A SOCKS5 proxy load balancer with automatic health checks.
• stupidict — An offline English-Chinese dictionary for the terminal.

You can install them from my Homebrew tap with brew install mingcheng/tap/<package>. Browse my GitHub repositories for more projects.
