I'm improving performance and quality of images on the web
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.
The best possible widely-compatible compression of images with an alpha channel.
GUIs making image optimization easy and convenient
A free web service for filtering out spam in web forms (blocking HTTP spambots) transparently to the users and accessible to screen readers.
Halving bandwidth of the Internet cat traffic.
Auto-updater for non-Appstore (and thus DRM-free) Mac apps.
I'm also maintaining several libraries and tools for the Rust programming language.
