First of all I'll need to have an insight into the application itself, number of tables, number of input forms, reports, etc. before giving the final estimate.
More than 13 years of expirience as developer.
Designed and developed a lot of web and desktop applications.
From desktop applications I developed I can point out Emergency dispatch centre and vehicle tracking, Real estate management application, School administration application and various GIS applications. From web based applications I can point out Mobile voting for Vipnet croatia, Croatian diabetes registry, Croatian cml registry and Croatian acromegaly registry.
Have a very broad knowledge in C#, Delphi, Visual Basic, HTML, ASP, ASP.Net, PHP, Oracle, SQL Server and MySQL, so you're free to choose the technology you want
