Oson Savdo: an OpenCart demo store (in progress)
A demo OpenCart 4.x store with custom multi-currency checkout and Telegram order-notification modules.
Clients looking for an OpenCart developer struggle to judge the level of custom work from a résumé alone — they need a working example with original modules, not marketplace plugins.
Building a demo store on OpenCart 4.x with two custom modules: multi-currency checkout with local payment methods (Payme, Click in sandbox) and Telegram order-status notifications via the event system, without patching core files.
The project is in progress: the spec is ready, implementation is underway — once live it will be a working portfolio link.
