Welcome!
This repository showcases my journey from Senior Software Development Engineer in Test (SDET) to Data Analyst, demonstrating expertise in SQL, Python, Power BI, ETL, cloud analytics, and business intelligence.
I have over 10 years of experience designing enterprise software solutions across Finance, Insurance, Healthcare, Education, and Entertainment industries.
