  • Long-Term Financial Stability Prediction
    [01]Freelance Project
    Long-Term Financial Stability Prediction

    Created a hybrid stacked model with Scikit-learn and XGBoost to predict 3 factors of long-term financial stability. Constructed 6 Matplotlib visualizations for each factor to identify patterns, and detect outliers, strengthening the model. Presented actionable insights to stakeholders for strategies to improve financial stability, specifically lowering debt.

    Mind the Gap: Predicting TTC Subway Delays with a Machine Learning Approach

    Developed predictive analyses by building a TensorFlow neural network in Python to forecast TTC subway delays, achieving an MSE of 1.1. Created Matplotlib visualizations to reveal delay patterns, recommending prioritization of transfer station congestion mitigation. Presented 3 actionable recommendations to several stakeholders on strategies to improve handling TTC delays.

<Financial_Modelling_Case_Competition>

Developed a stock price prediction linear regression model with Scikit-learn to derive 6 trading and hedging strategies. Visualized the LSTM, ARIMA, and linear regression predictions against the actual prices with Matplotlib, with linear regression having the closest predictions. Ranked top 5 out of several teams for effective hedging strategies and predictions.
