With over 15 years of experience as a software engineer, I have a passion for designing and developing scalable, reliable, and cost-effective data pipelines and web applications using cutting-edge technologies. My field of expertise is in cloud computing, especially Apache Spark, Kubernetes, and Containers. I currently work at Coupang, one of the fastest-growing e-commerce platforms in Asia, where I contribute to the company's mission of creating a world where customers wonder "How did I ever live without Coupang?".In my current role, I have designed and developed a data pipeline utilizing Apache Spark, Amazon EMR, and Cassandra, which processes over 10 TB of data daily. I have also successfully migrated Apache Spark jobs to a Kubernetes environment from Amazon EMR, leading to a 30% reduction in AWS cost and increased developer efficiency. Additionally, I have created REST API endpoints using the Spring Framework for both a search results page and a catalog management system for imported goods. Some of the skills that I have applied and enhanced in this role are troubleshooting technical architecture and back-end web development.
Listed skills include Jsp, Distributed Systems, Git, Amazon Web Services, and 20 others.
