Development of web sites with server rendering for sales of devices for smart homes

Москва, Россия

The company deals with the delivery of ingredients with recipes for cooking. Tasks that have been successfully completed with this company: - Rewrote from scratch the website for clients. Emphasis was placed on user-friendly interface for quick and clear ordering of goods. - Also one of the goals was to make the site optimized for search engines and fast loading on any client devices, so SSR technology was chosen for development. - To save budget it was decided to develop a mobile version of the site and package it through Cordova framework instead of native development. The site worked with native mobile API (Push notifications, use of local memory for application persistence, work with phone camera, API for offline work of the application). Supported mobile platforms - iOS, Android, Windows Phone- Improvement of the existing CMS on ExtJS
