An experienced software engineer with advanced skills in Apache Flink, Apache Spark and Airflow, I am seeking a challenging opportunity to be a Data Engineer and Machine Learning Engineer where my extensive experience, education and training can be fully utilized.

• Design and develop a profile recommendation system, matchmaking system and data pipeline for low latency inference. This system handles 180 million requests per day.
• Develop the data pipeline based on AWS and Spark, manipulating data growing at a 150x pace over four years.
• Implement Real-time Fraud Prevention System to detect and punish abnormal behavior patterns using Apache Flink and Kafka.
• Support data-driven decision-making culture by developing A/B Test systems and 50+ experiments.

I've learned CS @ SNU and Data Science @ UBC.
