GK System

Probably my biggest project is the GK system. Via this system are managed all postal packages, mail delivery, and advertising distribution processes. GK system also includes the printing of customer invoices, customer debts and incidents management. Basically, this system covers all business processes in this area.

This system was designed by a few months and the first version came out in early 2010. This system uses the UAB "Greitasis Kurjeris" company. Since then, this system is still expanding and evolving.

Since this company is large and located in all regions of Lithuania and it has a lot of workers, this system works using internet. This project currently uses the following technologies: .NET Framework 2.00 C#, MSSQL / T-SQL, Java (Android application), XML SOAP Web-services, ASP.NET. Also this system includes strict security and cryptography algorithms like: RSA, AES & etc...
