Machine Learning Engineer + MS SQL Developer

Remote work · $4350 · More than 10 years of experience · Upper Intermediate

The last project: behave, Luxembourg, Grand Duchy of Luxembourg. I was responsible for developing of a sophisticated analytical system: Refinitiv’s financial information analysis for investment professionals. A database was created from the scratch. Extremely efficient stored procedures for statistical and analytical processing of huge amounts of financial information in the context of each day for decades were developed (hundreds of millions and billions of records in tables to proceed). Machine Learning were used for results forecasting (MS SQL R Services and Azure Machine Learning Studio). Approaches how to reduce the cost of using Azure Machine Learning Studio were found. Easy-to-use structured and well formatted analytical reports for clients directly in Excel format by means of MS SQL Server with emailing were created. The active development stage of the system is successfully completed.

Ph.D., technical sciences, the topic of the thesis was pattern recognition and multi-class classification – classic machine learning challenges. For the last project, data processing with recursive call of three levels of nesting stored procedures and result of intermediate calculations at each step were developed. Recursion is a common practice for tables (CTE). But for stored procedures, I did not find anything similar on the internet forums. Machine Learning were used to build models for results forecasting. With correctly prepared data and "Two-Class Decision Jungle" model Accuracy = 0.865 was achieved.

I'm interested in getting a new related to information-analytic activities job. Development of sophisticated AI driven MS SQL based information-analytic systems. Development of new and improvement of existing MS SQL databases and analytic reports. At the moment I can be useful as Machine Learning Engineer, MS SQL Developer or Data Analyst. In the future, I’m going to grow to the level of Data Scientist. In order to achieve this goal, I am already learning the course “The Data Science Course 2020: Complete Data Science” by 365 Careers, that I bought on udemy.
