    Figure Technologies creates innovative consumer financial solutions for home improvement, debt consolidation and retirement. Its mission is to build and promote innovative financial products on blockchain that benefit consumers and eliminate the rent-seeking, illiquidity and other inefficiencies in current financial markets.As Senior Director of Data Engineering, I am responsible for the data architecture, engineering, and operations that support analytics, reporting, and data science. As one of the earliest members of the data team, I built our data infrastructure from the ground up, including:- Created streaming data ingest from event-driven Kafka architecture, with on-the-fly process that translates protocol buffer schemas defined in multiple microservice applications into BigQuery data structures that evolve in real time. - Designed and built Python ETL of operational message formats into dimensional data lake, with schemas optimized for reporting and analytics.- Implemented Airflow on Google Kubernetes Engine, enabling automation of many thousand jobs each day.- Built ETL framework in Python, pyspark, and BigQuery, providing the reporting benefits of a dimensional data model (slowly changing dimensions, accumulating snapshots, and fact tables) without the overhead and expense of a data warehouse or ETL tools.- Automated data ingest from credit agencies and property data brokers, wiring legacy batch flat file formats and technologies (sftp, etc.) into our architecture and allowing data scientists to focus on direct mail models instead of file logistics and data hygiene.
