In this project, I developed an insightful dashboard using Power BI, meticulously analyzing a substantial Excel workbook containing 50,000 rows of data. This comprehensive analysis enabled the business to visualize key metrics and trends, ultimately empowering decision-makers to drive informed strategies and optimize performance. The dashboard serves as a vital tool, transforming complex data into actionable insights that facilitate better business outcomes. Through this project, I demonstrated my ability to leverage data analytics to support strategic initiatives and enhance operational efficiency.

DataBridge AI (Portfolio Build)

A self-initiated build demonstrating end-to-end analytics engineering. DataBridge AI is a Streamlit-based platform covering the full data pipeline: upload CSV, Excel, JSON, Parquet, SQLite, or connect directly to a SQL database, with automatic header detection, whitespace cleanup, and date conversion on import.

The platform includes AI-assisted column mapping with confidence scoring, a 0–100 data quality engine, outlier detection (IQR/Z-score), feature engineering tools (encoding, scaling, binning, text extraction), and a no-code ML Studio for classification, regression, and clustering.

Also includes a dynamic KPI and target tracker with automatic achievement calculation, and an AI assistant for dataset summarization and analysis — built to showcase range across data engineering, ML tooling, and applied AI.
