Техническое сопровождение сайта косметики

During several years periodically work with this site as 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 & Database optimization
- Redesign & new front-end functionality
- Upgrade Opencart admin functionality etc.
