- Devised and implemented a bank machine learning model that decides which client is eligible for a payment holiday.
- Collected relevant data from the bank, preprocessed the data by handling missing values, and feature engineering.
- Trained the machine learning algorithm, which was logistic regression, and evaluated its performance using accuracy and precision metrics.
- Deployed the trained model in a Python application to make predictions on new client data.

- This was a project to devise and implement a solution that would use publicly social media data to solve any of the biggest problems currently faced by South Africa
- I and my team came up with a solution to use publicly available data to address unemployment in South Africa
- We achieved this by scrapping data with Python and tools like beautiful soup and implementation of the crawling logic
- I was responsible for building the predictive model and evaluating its performance
- We then deployed the model into the web application to connect job seekers and employers based on the model's recommendations
- This model was aiming to contribute to a reduction in unemployment rates of South Africa
