Mathematician: responsible for analyzing mathematical models of the existing solutions using Computational Mathematics, Mathematical Analysis and Theory of Algorithms to analyze data integrity, implement resource consumption optimizations and improve performance of mission critical processes. Analyze data related issues, the numbers and trends of data inconsistencies, performance and resource consumption problems. Statistically and experimentally validate the model improvements over test and historical data while constantly adjusting algorithms to keep the model up to date. Integrate validated changes of key parts of the solution into a number of customer`s legacy projects, which were built with the use of different programming languages. Participate in architecture design and development of any part of software solution. Perform monitoring of performance in production environment with the use of asynchronous logging, custom Performance Counters, Event Logging, Tracing.
