For Swedish Post (the leading Swedish mail operator) I developed PostnummerGuide which was small Windows application, downloadable from Swedish Post’s website. It enabled the user to quickly search for addresses and postal codes in Sweden.
The database was highly compressed, in a proprietary format that we developed in-house, enabling us to deliver some 600.000 records along with executables in less than 4 MB of data.
The application was downloaded over 150.000 times per year.
Platforms: Windows
Techniques: Delphi, C++, ZIP
