- Professional Journey: I work as an AI Product Manager at Extendify and have a background as an Engineering Manager and Full-Stack Web Developer.
- WordPress Expertise: Over 15 years in the WordPress ecosystem, I have been featured in People of WordPress and have organized monthly community meetups for 7 years.
- Interests: Product Management, Artificial Intelligence, Productivity, and WordPress.
- Content Creator: In addition to this blog, I’ve been writing PainelWP, a weekly newsletter about WordPress in Portuguese, since June 2019.
- Hobbies: I love watching movies and wrote reviews as a hobby for a few years. I also enjoy drawing, especially with watercolors.
