About

With over 9 years of experience in data science, I am passionate about applying artificial intelligence and machine learning to solve real-world problems and create positive impact. My field of expertise is fraud detection, where I have developed and deployed scalable and robust systems to protect millions of customers and transactions at Gopay, the leading digital payment platform in Southeast Asia. As a Senior Data Scientist at GO-JEK Tech, I work with a cross-functional team of engineers, analysts, and product managers to design, implement, and evaluate AI & ML models for detecting and preventing fraudulent activities, such as account takeover, Promotions Abuse and identity theft, social media scam. I use various tools and techniques, such as python, Neural Networks, Machine learning , Deep Learning, Graph neural networks, Graph analytics, Sql and Data Analytics to ensure the accuracy, efficiency, and reliability of our solutions. I also contribute to the continuous improvement of our data quality, pipelines, and infrastructure, as well as the sharing of best practices and insights across the organization.
