I was part of the Data and Business Intelligence department, maintaining process documentation and handling internal client queries. I configured backend changes using SQL Server and tracked tickets in Jira.
I also used Python and Excel's Py function to automate and accelerate SQL query performance, and collaborated on templates to prevent recurring errors. At Reloadly, I tested and managed APIs using Postman and supported customers with product issues.
Right now I am built machine learning models like Random Forest, XGBOOST, SVM and by using Tensorflow.
