    Emil Drkušić

    experienced database developer, programmer, financial analyst

    Croatia - Last active: 1 day ago - Tests: 1

    My jobs so far included analysis of customer requirements, consulting, coding and deployment on two major projects (one was developing ERP for telecommunication sales company and other was on-line system for tracking shares and funds values), work on few smaller projects and teaching (databases, math, programming, logic). Most of smaller projects were applications based on MS Access, usually connected to MS Excel as data source or output for further analysis. Most of my work was/is related with databases from database modeling and coding and than producing complete applications with GUI. Technologies I used so far were MS-SQL, MySQL, MS Access+Ms Excel (few complete applications with more than 50 forms each in usage by clients), C++, Pascal. Maybe most interesting is development of complete MS Access applications as well as using VBA in Access or/and Excel, but feel free to contact me for any of above. I think that my experience and knowledge are enough to get job done faster (and of course cheaper) but not loosing any quality in process.
