• Migrated from on-premise, multi-tenant Confidential Hadoop cluster to AWS EMR.
• Added Path Processing to improve product quality on arterial roads by 15 percentage points.
• Drastically boosted probe extraction performance by >350% with increasingly larger input data through code improvements.
• Achieved >50% performance increase of modeling jobs by adding parallelization.
• Removed manual process and improved local time conversion accuracy by up to 20% (depending on region) by redesigning time zone identification approach and collaborating with map artifacts team on creation of new artifact to support better solution.
