I analyze the data and processes of the company to improve the efficiency of employees (work with data to track the digital traces of employees). I am writing technical specifications, I am developing algorithms for processing and calculating indicators in SQL (ETL) and Python. I participate in the analysis of distributions and emissions. I interact with internal clients, I participate in all projects of our division. I know very well the main DS and ML libraries (Pandas, Sklearn, Matplotlib, NumPy, Seaborn, KNN, Logistic regression, Decision tree, Random forest, etc.). Familiar with PD and LGD models.

Completed an internship on a course in data analysis and machine learning. Projects were developed: determining the reliability of credit borrowers, predicting the liquidity of housing, determining the prospects of mobile operators' products, distributing the votes of Moscow residents by districts using the clustering method, etc. I work with libraries: Pandas, Numpy, Matplotlib, Scikit-Learn, Sklearn, TensorFlow, Scipy, etc. I can visualize the results of my work using built-in libraries, such as Seaborn, Matplotlib (scatterplots, histograms, bar charts, rectangular charts, etc.). I use machine learning algorithms in my work: the method of nearest neighbors, clustering, linear and logistic regression, decision tree, support vector machine, random forest, etc. I know Python, advanced Excel, advanced SQL, basic C ++

I worked with the company's customer database, analyzed customer inflow/outflow, predicted purchasing power and the likelihood of a customer leaving. Divided and analyzed data by various parameters, segmented, clustered, and grouped into categories. Analyzed the success of startups before and after roadshows. Researched and analyzed the market, pre-processed data, tested hypotheses. Prepared charts and presentations. Worked with libraries: Pandas, Numpy, Matplotlib, etc.
