Matomo / Piwik Analytics

Contributed to the Matomo/Piwik open-source analytics ecosystem, including piwik-ruby-tracking, a Ruby gem that integrates Piwik tracking into Sinatra, Padrino, and Rails applications, and IPv6Usage, a plugin for monitoring IPv4 vs. IPv6 visitor traffic. Both projects are used by self-hosted analytics installations as privacy-respecting alternatives to third-party tracking.
