K4ryuu

Hi, I’m K4ryuu - a university student and open-source developer.

Alongside my studies, I work on a mix of modern web applications, game server tooling, and low-level reverse engineering projects. I design and build systems end to end, from backend logic and infrastructure to developer-facing tools.

A large part of my open-source work is focused on game modding, especially around the Source Engine and CS2 ecosystem. I build server plugins, frameworks, reverse engineering tools, and utilities that help developers extend, analyze, and work with complex game systems.

Many of my projects come directly from real-world needs. Tools like IDA-VTableExplorer and various CS2-related projects started as internal solutions and later became open-source because others ran into the same problems.

Sponsorship helps me spend more time on open-source development, research-heavy work, and polishing tools that people actively use. If any of my projects have helped you or your community, your support directly contributes to future improvements and new ideas.

Thanks for supporting independent open-source development.
