Last year, I completed the development of an application for my company, which allowed me to collect a dozen data sources in one place, consolidate them and visualize key KPIs. The convenience of the application made it possible to facilitate the work of an entire oil production monitoring unit and free about 50 percent of the employees' time from routine.
My name is Darya Bezrukova, I have been working in the professional field of data and visualization of data for 4 years. My first experience was as a junior BI Developer. I created the large application for the marketing department, it collected data from all over the country and presented this amount of information in a convenient way. The aim of app was evaluating the success of the marketing campaigns, taking into account seasonality, geographical location and "cold / hot" customers. 
Further I mastered in BI Development, I work with a large customer, the company "Burger King". I gathered data from the databases of the company, the official website and the mobile application. The aim of the project was to create an application to identify and analyze negative reviews to highlight weaknesses in customer service.

Also, for the entire management team of the company were implemented a report and send out pdf reports using NPrinting technology.

Algorithms for calculating bonus factors and vacation employees were implemented. The main emphasis in the work was aimed at data verification.

The main focus was working with advanced visualization.
