Experience
Class for Caching
I worked actively on a class for caching the rendered pages of a PDF document. It can automatically cache pages near the requested one in the background. The number of cached elements can also be limited. Since the application can rotate pages, such actions should invalidate the cache, so the CacheEntry keeps the value of the page rotation angle, which was actual when the page was rendered, and the image was cached. For this project, I used .NET 3.5.
Onboard Forest Fire Monitoring Control System
An application designed specifically to monitor forest fire situations. Features include vector maps, GPS tracking, track re-coding, real-time data communication (navigation data, fire information, other information related to danger situations), and reports generating. The main requirement of the app was reliability.
Yasen Project
A distributed telecommunications system for gathering, transmitting, and processing forest fire data. The system includes many minor nodes with Yasen installed. Every workstation includes modules for data input, preprocessing, and transmission. The major node has a specific Yasen instance which receives all the data, processes it, publishes it to third-party governmental systems, and generates over a hundred kinds of reports.
