OpenCart Custom Module Development Tutoring

I'm seeking an experienced OpenCart tutor for 4 hours each weekend, specifically from 8:30 pm to 10:30 pm Indian Time. My primary focus during these sessions will be learning how to create custom modules, as I currently have no experience in this area. But I know PHP and MySQL well. However, I would also like to cover theme customization

Ideal Skills:
- Minimum 4 years of OpenCart CMS customization experience
- Profound understanding of theme customization and module development
- Excellent teaching skills

Please share your OpenCart customization experience and any relevant examples.
