Experience

Triatlon

Triatlon is based on two applications; one that generates images based on bank database data and an image template, and second, integration into an OS Shell (Windows OS) that displays generated images on employee desktops (over 400 desktop computers). The server-side application is built in Java and collects data from the Oracle database, then generates images with numbers and graphs. After an image has been generated, it publishes that image on the intranet Nginx server. Clients check for a new version of the image on a specific intranet location and downloads and displays it over the users' desktop.

STONEE

This utility billing software system (Power Consumption Billing System) consists of several applications integrated into a large system. It serves over 400,000 customer accounts. The system is based on several Windows and web applications, integrated over an OLTP system (Oracle database with business logic written in Oracle PL/SQL and Java classes in the database), and a custom-made DWH system (Oracle database). There is external integration with SAP ERP (FMIS) and other systems. The application was developed using C# (.NET WinForms), Java (Vaadin web forms), JasperReports for reporting, Oracle APEX and Oracle PL/SQL in the back end.

Gaius

Gaius is a legal office management software (case management software). I was the team lead for the group of developers that built Gaius. We used Java with the Vaadin framework and Oracle database, and JasperReports for reporting.

City Parking Management: A Smart City Solution

City parking management is a custom-made application for the controlling of car parking. The system is composed of a supervisor web application, Android apps for field supervisors, and integration with SMS payment from telecom providers. I developed the first version of integration software based on the ParlayX protocol.

PIS: Financial Management Information Systems (FMIS)

As a part of the team, I designed and developed a financial management information system for a large enterprise. Based on the Oracle database, the business logic was developed using Oracle PL/SQL and Java in the database. The client-side was developed in C# (.NET WinForms).

Koncesije

I was the lead designer and developer for the Concession contract management system (project). It was built using the Oracle database express edition and C# (.NET WinForms). Crystal Reports (SAP BO) was used for reporting.
