Projects

Java to SQL Compiler

Source code

This compiler is written using Java and Antlr where you write java code and SQL code is produced. It also handles reading CSV and JSON files.

Technologies used: Java, Antlr.

THE BATTLE OF NEIGHBORHOODS

Source code

A system that enables the citizens to select the safest borough in Chicago based on the total number of crimes between 2010 and 2018. The system also allows to explore the neighborhoods of that borough and find the 10 most common venues in each neighborhood. Finally, it clusters the neighborhood using k-means clustering.

Technologies used: Python.
