Gregory Smith

Built out data processes for a new data service product offering and collaborated with 2 teams and C-level executives to successfully launch the service from beta to production in under 3 months. Optimized data service ETL/ELT pipelines that resulted with an average 600% speed-up and ramped up development & testing velocity to reach project deadlines. Developed a platform-wide fuzzy matching solution in Java and Groovy that enriched data insights by linking ~15% of unaccounted-for data; this solution achieved a 98.9% match rate on two sets of 1,000,000 records in under 10 seconds. Implemented efficient bulk data quality processes in Java & SQL Server that standardizes data flowing through all ETL pipelines. Architected and delivered a fast & flexible data extraction solution in Java using multi-threaded JDBC connections that was designed to quickly adapt to a client’s ever-changing requirements. Led efforts to improve code and pipeline documentation coverage by 15%. Enhanced developer efficiency over 10% by replacing manual pipeline debugging and testing efforts with a common set of development tools. Drove down the total time of a client’s vital data migration/conversion from ~4 days to ~12 hours by learning Oracle & batch scripting on the fly and automating the largely manual process to an optimized, parallel data process using batch scripts, Oracle, & SQL Server.
