Open source contributor in the core MooTools team and published several MooTools based libraries that got included in popular CMS (mostly Joomla) are still used on the web today (as some sites just never update).

Consulted on web development architecture with agencies and international companies, mostly spurred by my open-source work on MooTools and my open-sourced JS libraries.
