Tellmaps are merging map display, rankings, charts, and narrative in an easy to use interface used by UNESCO, IMF, IEA and others. Tellmaps are an attractive way to introduce data rich topics to varied audiences. Our job was redesigning the frontend into responsive layout and upgrading the whole system to new modern architecture heavily inspired by React and Flux libraries. Tellmaps is a typical example of a project where communication and common understanding is the key to success, since we work within an international team located in various parts of Europe.

BalteLevneji.cz is a web portal developed for TART corporation. It has two primary goals: the public part aggregates and publishes information about various possibilities of industrial and commercial packaging, and the VPN secured intranet serves as an organizing tool for individual business cases for company sales represenatives. It makes it possible to filter various business cases and to quickly find the one that helps the sales representative show their expertise to a potential customer.

A small investment in building this app helped TART corporation solve the issue of replacing experienced and knowledgeable representatives with new hires that lacked the epxertise and deep understanding of complex packaging systems.
