I can code almost everything you want to be inside your WordPress website.
- Web statistics;
- Sliders, Animations, User interfaces;
- Custom post types and metadata;
- Administrator page modifications;
- Custom post feeds and single views;
- Cartographical services;
- E-commerce (preferably WooCommerce);
- User access tasks;
Especially I'd like to notice WooCommerce, where I can make:
- Custom payment gateways;
- Custom shipping methods;
- Price modification;
- Subscriptions (with or without external plugins).
