I have took part of developing Doctorscreen. doctorscreen.kz there I wrote first version of the product then We complemented sometimes. Then I worked at GardExpress. That is Ecommerce application. I developed RESTful API for this project. Now I work at ORC project. That's also Ecommerce project but larger than GardExpress. In my plans I will rewrite Filter.php using Decorator. https://github.com/almatsboom/orc doctorscreen.kz - система управление поликлиник и онлайн скрининг рака (REST API and Backend Admin (frontend side учавствовал в разработке)) UmmaFood - доставка еды (REST API) GardExpress - mobile app E-commerce(REST API and Backend Admin) https://github.com/almatsboom
