I'm mingcheng (明城), an open-source practitioner from Ningbo, now living in Hangzhou, China. I love building useful software and working with the communities that keep it thriving.

I'm currently a senior software architect and open-source evangelist at Ant Group. Before that, 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, and lately I've been focusing on AI agents and infrastructure. I care about clean design, reliable automation, and turning good ideas into systems that actually work.

Linux is my go-to: Debian for servers and containers, and Kalpa Desktop on the desktop. 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. Here are some of the projects I'm involved with:

• 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 stream-batch graph computing; an Apache incubating project.
• Apache Answer — A Q&A platform for community knowledge sharing; an Apache top-level project.

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

• aigitcommit — Generate Conventional Commit messages with OpenAI-compatible APIs.
• mp3blstr — Play music with a terminal player inspired by mp3blaster.
• simplyddns — Keep DNS records up to date with configurable IP sources and DNS providers.
• socks5lb — Balance traffic across SOCKS5 proxies with automatic health checks.
• stupidict — Look up English words offline in an English-Chinese terminal dictionary.

They're all available from my Homebrew tap: brew install mingcheng/tap/<package>. You can find more projects on my GitHub repositories page.
