October 2017 - August 2019
I ensured data quality of several data streams (pharmacy / supermarket / drugstores DB), performing data cleaning and data manipulation. My daily work consisted of answering data queries by investigating raw data, operations tasks and working on projects. One example of a project is integration of a new data source, that involved working closely with development teams regarding new data formats and defining new data segments. Most of the analysis is done SAS scripting, and Python is used occasionally
graduation project (machine learning)
July 2016 - February 2017
The end goal of my graduation project was to create a prediction model that can estimate the lead time of an order (the calculation time of a software). I focused on data analysis, including various prediction models (lasso regression, elastic net, bagging and boosting methods) and development of a model which simulated the architecture of the software (based on Markov Chains).
