I am a software engineer and open-source maintainer from Hong Kong. I build high-performance image processing tools and infrastructure with Go, C, and libvips.
My work makes image and media processing faster, safer, and easier to operate.
- imagor — a fast, secure image processing server and Go library powered by libvips
- vipsgen — a Go binding generator for libvips with type-safe bindings for around 300 operations
- imagorvideo — video thumbnail processing using ffmpeg C bindings
- Imagor Studio — a self-hosted image gallery with editing, layered compositing, and reusable templates
I'm available for commercial support and consulting on imagor, libvips, and Go/C image infrastructure — see the consulting page for details, or email imagor@cshum.com.
For project questions or bug reports, feel free to open an issue in the relevant repository.
