I started a project for increase to our online sells and we needed a recommendation engine for this. I thought this and resumed to my managers. And they accepted this project. I coded it on Python and used appriori algorithm. This recommendarion robot is still working and our sells increased. I have so many similar r&d project and I'm still researching for new projects .

I forecasted optimized prices for our B2B customers and modelled a machine learning model. I used regression models and price flexibility for forecasting on prices. I used Python, Sql and Microsoft Excel for this project.

I developed to this project for our call center. This project is solving that problems, when should call my customer? Which I call to customer? Which our customer is may lost ? I used Python, Sql and Microsoft PowerBI. So I forecasted to candidate on churn customers by reggression models. 

We are sending SMS to our customers and sometimes out SMS package can finish so early and we must buy new SMS packages for sending SMS and this is a extra cost for company. I forecasted our count of the will send SMS. This model is still working and our call center is don't need new packages. I used Python, R and SQL.
