About Fraud Detection System 
FDS (fraud detection system) protects online transactions from fraudsters and abusers. We build highly sophisticated and analytics-based systems and services that scan massive amounts of transaction-related data (buyer, seller, payment, etc) to uncover underlying correlations and detect fraud and abuse patterns, as well as tools and processes for operation teams to investigate and act on these. A robust FDS protects Coupang’s brand and image, prevents negative impacts to Customers and Sellers and reduces revenue loss.

Our mission is to ensure that every transaction is trusted, safe, and protected from fraud. We build the brand image that
Coupang is a trustworthy place to buy things and do business.

How We Do?
By leveraging state-of-the-art Big Data technologies and machine learning expertise, we try to build a data-driven culture for fraud detection and risk management. We deeply believe in the machine learning approach to fight fraudsters and protect our customers, and are the early adopters for Big Data and Machine Learning technologies at scale in Coupang.
We view Big Data and Machine Learning as our core strengths. Starting from data acquisition to predictive models, FDS Tribe teams are organized into several smaller groups including FDS Commerce, FDS Payment,  FDS Data Platform and FDS Science.
