I've created and maintain several open-source projects. Some of them, like pngquant and MozJPEG, power many 3rd party tools and services that save huge amounts of bandwidth worldwide.

• pngquant and libimagequant

  The best possible widely-compatible compression of images with an alpha channel.

• ImageOptim app & ImageAlpha

  GUIs making image optimization easy and convenient

• Sblam!

  A free web service for filtering out spam in web forms (blocking HTTP spambots) transparently to the users and accessible to screen readers.

• lossy animgif + gifski encoder

  Halving bandwidth of the Internet cat traffic.

• Sparkle

  Auto-updater for non-Appstore (and thus DRM-free) Mac apps.

I'm also maintaining several libraries and tools for the Rust programming language.
