      • After the project I carried out by INNOSA SOFTWARE was purchased by ESHOT General Directorate together with the source codes, I was transferred to ESHOT General Directorate. The project is still in use and it is an application where additional developments are made over the structure I have established in line with the needs. In addition to this project, some modules of the institution's Automatic Fare Collection System (AFC) were included in the application. Boarding data from 3000 Validators used in the field, charging data from 1000 POS devices and 250 TVM devices were also transferred to the system. The backend side of the project, whose Embedded System side is being carried out by a different team, is followed in the Public Transportation System project. Integration with all external systems is provided via Web Services. In the database that has 10 Terabytes where it uses the system; Daily average of 1.6 million boarding data, 1.4 million charging data, 25 thousand trip data, on average 3 million data are processed. Within the scope of the project, C#.NET, ASP.NET MVC, WCF, WPF, ORACLE PL/SQL, JavaScript, DevExpress Component technologies were used. Microsoft POWER BI is used in our company in order to create reports, analyze the outputs of this application and to develop business processes. I perform ETL processes and create statistical reports using POWER BI. The data sets to be created for all the layers that POWER BI needs have been prepared by me. All the lines, trips, stops, routes and timetable data is transformed to GTFS format and served to Google Maps by PL/SQL codes including GIS data. The actual data is updated automatically to Google periodically. Show less
