Creation of algorithms providing quantitative chemical analysis for LIBS systems

Senior data scientist

Development of algorithms for numerical chemical analysis, filtration of non-focus spectra, classification of materials based on spectral data for several dozens of companies from a mining industry

Laser distance spectrometry, Icon steel

LIBS (Laser Induced Breakdown Spectroscopy) is a modern technic for non-destructive online chemical analysis. The basis for creating an algorithm for chemical analysis are the spectra of the system's spectrometer. The aim of the project is to create quantitative chemical analysis algorithms based on spectral data resistant to various factors, such as changing laser power, dustiness, humidity, temperature, etc.

Managing subscription tariff plans

Senior analyst

Сustomer behavior models development in the situation of changes in the grid of tariff plans, as well as the search for new tariff plans that maximally satisfy customers and the photobank

Depositphotos

Photobank has many tariff plans for different groups of users. Introducing new plans or changes to existing ones is possible only after modeling of customers behavior. The project goal is to find most possible scenarios of user reaction and search for optimal tariff plans for both customers and a photobank
