I assisted in ETL workflows using SSIS and Pentaho, contributing to data cleaning and transformation for reporting, and built Tableau dashboards to track operational KPIs. I created BRDs, data flow diagrams, and technical documentation to support cross-functional collaboration. My work included applying machine learning models (Regression, Decision Trees, Random Forests, SVM, XGBoost) and deep learning techniques (LSTM, CNNs with TensorFlow/Keras) for predictive analytics and forecasting. I also designed and managed data warehouse workflows with SQL Server, Azure ML Studio, and Talend, while supporting agile projects using GitHub, Jenkins, Jira, and Confluence.
