Worldwide Coronavirus Statistics
During the COVID pandemic, I wrote a live-updating global coronavirus tracker website at https://covid-019.com.
The back end data processing is written using Python using the pandas library, which normalizes data from different sources into CSV files for different regions. It also decides which data source should be treated as authoritative for each region.
An application written with the Express.js framework ingests the CSV files that the Python script outputs and converts them into nice looking graphs using HTML, CSS, and JS. Graphs are generated using the d3.js library, and every component is scalable and Dockerized.
At its peak, the website garnered over 500 unique visitors per day. This presented code efficiency and reliability issues, which I was able to solve by leveraging the nginx web server to cache pages for a short period.
