Data Analyst with experience using Agile methodologies. I develop advanced SQL queries, debug existing queries and troubleshoot for performance tuning and faster run time. I extract, manipulate, and analyze data from PostgreSQL, MySQL, SQL Server or SQLite databases, NO-SQL databases, and cloud platforms including AWS, Google Cloud Platform (GCP) and Microsoft Azure and their respective data warehouses including Redshift, Big Query and Azure Databricks.
I have a proven record of presenting business insights from multiple sources of data using ETL/ELT tools to prepare the data prior to developing dashboards & visualizations in Tableau. I use Python scripts for data cleaning, data transformation and for automating workflows & data wrangling tasks. For smaller size datasets, I turn to MS Excel or Google Sheets to conduct advanced or less complex data analysis, working with Pivot Tables, VLOOKUP, logical & conditional aggregation functions to create dynamic dashboards in MS Excel or GS.
