🧠 Data Quality Dashboard

A Full-Stack + Data Analysis project designed to monitor, visualize, and improve dataset integrity in real-time.
Built with Python, Pandas, Matplotlib, and an interactive Streamlit frontend — this dashboard empowers data professionals to identify and resolve data quality issues quickly and efficiently.

⚙️ Note: The live backend (hosted on Railway) was part of a trial deployment and is currently inactive.
The application runs perfectly on localhost, where all backend and frontend features function as intended.

🚀 Features

  • 🧩 Automated Data Cleaning — Detects and handles missing values, duplicates, and inconsistencies.
  • 📊 Error Rate Computation — Calculates error ratios and data completeness metrics.
  • 🎨 Interactive Frontend (Streamlit) — Real-time charts, filters, and summaries for better visualization.
  • 🔄 End-to-End Integration — Backend API (Flask) connected with Streamlit frontend for seamless operation.
  • ☁️ Deployment Ready — Designed to run both locally and on cloud platforms like Railway or Render.
