Skills
PowerBI
I know how to estimate and develop PowerBI reports ranging from simple to complex, utilising DAX, M, SQL languages, and advanced features such as RLS/OLS (row/object-level security), calculation groups, field parameters.
Python
I have experience building hobby projects that focused on creating OOP Python code, such as web scrapers (using Selenium and BeautifulSoup), simple websites (Flask), or transforming/modelling data (Pandas).
Databricks
I have successfully completed a couple of projects where I was required to modify existing ETL pipelines through PySpark on Databricks, and then orchestrate it with Azure Data Factory.
SQL
I write complex DQL (Data Query Language) queries to feed data into my dashboards - including CTEs (Common Table Expressions), window functions, and regular expressions. I also have experience with DML (Data Manipulation Language), and DDL (Data Definition Language) - inserting and modifying data, and defining views and tables.
