Social Skills

convert client requirements to a fully functional software. Manage change and communicate the client impact of every change requested

Tobas (barcode generator – desktop application for PC and MAC)

I have developed the software following the Argentinian laws that specified the barcode structure. We had a market opportunity that needed to beed fulfilled in less than 2 months, so both systems (PC and MAC) were developed meeting the market deadline. This software had such a good impact on the print industry, that we have been interviewed by the most popular print industry magazine in Argentina.

Technologies

Delphi, JAVA.
