In this project, I created and trained a model that can predict the south African language in which a given text is written.

Load shortfall-Predictor

In this project, I built a model that predicts the shortfall between energy generated by fossil fuels and energy generated with renewable sources.

Pretoria School Finder App

This project involved creating a function to recommend nearby schools based on location input and deploying a Streamlit web app for easy access. The user can input your town/suburb in the city of Pretoria and it will recommend the nearest schools to said location.
