Technical accompaniment of the cosmetics website

During several years periodically work with this site as a freelance front and back developer.
I perform tasks of any complexity. Here are some of them:
Opencart Modules: integration, rework and create custom
SEO & Speed and Database Optimization
Redesign and new front-end functionality
- Upgrade Opencart admin functionality etc.
