• Utilized Gaussian Mixture Model in R to cluster stores based on customer purchasing behaviours using variables such quantity of item categories sold at various times of day.• Developed a time series model to decompose daily sales into seasonal, trend, holiday, and weather components, providing a clearer understanding of how each factor contributes to sales fluctuations• Implemented optimization model to generate prices for food and beverage (F&B) clients and conducted training sessions to ensure wider team adoption

Singapore

• Utilized mixed logit model to measure item and store elasticity to identify customers’ sensitivities to price changes to generate price recommendations according to customers’ willingness to pay• Performed optimisation using genetic algorithm on Python, leveraging the obtained sensitivities and relationships between items to generate pricing recommendations that maximize F&B clients' profit and minimize guest count losses• Performed A/B test using hierarchical Bayesian model to analyse the performance of a pricing strategy trial implemented on the test group

Singapore

• Analysed transactional-level data extracted using SQL to deliver insights for F&B clients on topic such as performance of promotional campaigns and pricing activities• Created a Power BI dashboard that automatically updates performance metrics of F&B stores, enabling easy monitoring and quick analysis after promotional or pricing activities• Performed data cleaning to ensure that all analyses were performed using accurate data

Singapore

• Researched on the methods of modelling price elasticity of demand of items and implementing the mixed logit model on R using the Stan package• Wrote a literature review on possible time series methods for use in analysing and predicting sales
