NYC Building Permits Dashboard

Project Overview
I developed a sophisticated web-based dashboard that transforms raw NYC building permit data into interactive, actionable visualizations. This project demonstrates my expertise in data processing, geospatial analysis, and full-stack development.
View the live dashboard here.
Key Technical Achievements
- Advanced Data Processing: Implemented efficient data pipelines using Pandas and GeoPandas to handle large-scale permit datasets
- Interactive Visualization: Created dynamic visualizations using Dash and Plotly, enabling real-time data exploration
- Geospatial Analysis: Developed innovative hexagonal mapping techniques to visualize permit density across NYC
- Scalable Architecture: Designed a modular codebase that separates concerns and enables easy maintenance
Technical Implementation
Data Processing Pipeline
The dashboard’s backend leverages Python’s data science ecosystem to clean and transform raw permit data:
- Data Cleaning: Automated preprocessing of permit records using Pandas
- Geospatial Processing: Utilized GeoPandas for spatial aggregation and mapping
- Optimization: Implemented intelligent caching and aggregation strategies for handling large datasets
Visualization Components
The frontend features several interactive elements:
- Time-series analysis of permit issuance trends
- Choropleth mapping with hexagonal binning
- Dynamic filtering by permit type and time period
- Responsive design for various screen sizes
