Do meaningful things with like-minded people.

We're a small engineering team from Shenzhen, China, building real projects, keeping them open source, and improving with every commit.

Everything we do starts from problems we actually ran into while building our own products. All of it lives right here on GitHub.

Designed for Minecraft server networks that need reliable player state synchronization across multiple servers, built on Fabric.

• Redis distributed locks + optimistic version control prevent conflicting writes
• Seamless player state transfer between servers

Java Fabric Minecraft Redis

A zero-Spring data access layer for Java — one lightweight library, works with any framework.

• One consistent API over MySQL, PostgreSQL, SQLite, MongoDB & Redis
• Annotation-driven schema sync & versioned SQL migrations out of the box
• No Spring dependency — designed for standalone Java applications and game servers

Java Persistence SQL NoSQL Apache-2.0

An AI-assisted English reading tool that translates PDFs while preserving the original layout — built for anyone who needs to read and understand technical documents, not just quick machine translation.

Python AI PDF

We're early stage and still growing — learning and improving with every release. But every repository here is real code solving a real problem we hit ourselves — no vaporware, no buzzwords.

What you can expect from us:

• 📦 Build in public — source code first
• 🔁 Ship, iterate, refactor
• 📈 Continuously improving our engineering practices

Found a bug or have an idea? Issues and PRs are always welcome in any of our repos. Before contributing, please check the target repository for contribution guidelines. If our projects are useful to you, consider giving them a star — it helps others discover them.
