What I'm looking for

I'm looking for a data-focused role where I can build reliable ETL workflows, analyze business data with SQL and Python, create decision-ready reporting, and grow through hands-on work with cloud data tools.

I've built a sales data engineering and analytics pipeline that turns raw CSV sales data into clean, normalized MySQL records and business-ready reporting.

Using Python, Pandas, SQL, and MySQL, I developed automated validation and transformation workflows, analytical queries with CTEs and window functions, and dependable loading processes with batch inserts, transaction control, duplicate handling, error logging, and unit tests.

I've also built a solar-based battery voltage monitoring and protection system that captures real-time voltage and temperature readings, flags anomalies, and delivers live diagnostic output. In addition, I developed Expense Voyage, a web app for recording and categorizing travel expenses.

I'm currently completing a B.Tech in Electrical & Electronics Engineering while strengthening my data analysis, cloud, and Python skills through hands-on training in Data Science with Python and AWS Cloud Practitioner practices.
