-Developed a payment service recommendation engine with a Learning to Rank Algorithm (LTR) using AWS Sage

-Maker to compare and rank payment services for 1 specific product based on user and product data

-Used a LambdaMART loss function to optimise the ranking of payment services and penalise mistakes that cause relevant payment services to be ranked lower or less relevant payment services to be ranked higher

Implemented an API utilising ML to provide a hassle-free way for users to compare and find the best payment service for each transaction, allowing them to get the maximum reward out of all the payment services and deals available
