Valentin Kostin Email and Phone Number

• I have developed a lot of software for GIS data manipulation, such as data mining, manual assistance, and processing for production.• GIS data, obtained with this software, were bought by Google, TomTom, HERE, Yandex, Kasko2go, and other companies.• I have created a real-time road traffic safety backend that calculates accident rate, intensity, and traffic on a given road network. Input data are car tracks, weather data, and static parameters of the road network. This backend provides accident rate, intensity, and traffic in real-time tiles maps, requests by points, areas, routes, and various statistics.

• I worked on the car navigation software "PROGOROD" significantly improving it and backend during all time.• It was interesting to add in the application 3d-models, rasters, fine-looking texts, compact map format, Arabic language, and others.

• I was a head of software development department (5 subordinates). • I had designed, developed and released GIS "Talka GIS".• I had part-time work at V. A. Trapeznikov Institute of Control Sciences where I had written articles about GIS (mainly see mainly see link below).

• I had done essential part of software development for Earth remote sensing data processing. • I improved this product, added new features and released many new versions.• One of my achievements in computational geometry was the fast computation of Voronoy diagrams for segments and points in a plane.
