Intensive working on the project:

POSWeb browser for POS devices
During the period worked at APPI Tecnologia SA (named, today, as Muxi)

The POSWEB Browser is a software layer on the native operating system of POS, that assumes control of all resources of the terminal, enabling the POS to run applications based on remote servers connected to the network, using protocols based on TCP / IP (internet , intranets, HTTP, HTTPS, VPNs, etc..), and legacy protocols (SDLC, X28, ISO8583). The Browser accepts default WML pages (Wireless Markup Language), WML Script, and has features of advanced caching, allowing the pages and the scripts to be stored dynamically in the POS terminal with a large gain in performance.
