What I'm looking for

I’m seeking an entry-level Data Analyst or Business Analyst role.

At Zidio Development, I collected and preprocessed historical stock market data from Yahoo Finance and Kaggle, then built and compared four forecasting models: ARIMA, SARIMA, Facebook Prophet, and LSTM.

I translated model outputs into actionable investment recommendations, supporting data-driven insights on stock trends and seasonality.

For my Mobile Sales Performance Dashboard, I used Power BI, Excel, and DAX to analyze sales, customer behavior, and revenue trends across cities. The dashboard surfaced findings including Apple leading in revenue and Delhi recording the highest unit sales.

I also developed the Madhav E-commerce Sales Dashboard to track sales, profitability, and customer purchasing behavior. I’m seeking an entry-level Data Analyst or Business Analyst role.
