WordPress Origin Story

My open source journey began in 2011, when I created a free plugin to make WordPress multilingual using Multisite. I quickly learned that open source is more than code — it’s about community, responsibility, and sustainability. What started as solving my own need grew into years of contribution, collaboration, and sharing knowledge in the WordPress community.
