Description

Implemented J2EE/Swing applications at the US Marshals Service for management of enterprise sensitive but unclassified data. Converted large body of existing code from hand-written JDBC-based SQL queries to the Hibernate persistence layer, reducing code base by more than 20,000 lines while increasing portability to other database servers. Designed distributed architecture for future USMS enterprise system, featuring a new database schema comprised of over 200 tables combining elements of multiple legacy systems; a custom low-impact UUID generation scheme; and a checksum-based application update system for automatic delivery of client artifacts. Created extract-transform-load (ETL) programs to migrate legacy data into the new schema. Created applications for intra-agency data sharing, generating XML exports to multiple formats using JAXB, XSLT, and the Global Justice XML Data Model (GJXDM). Presented with Director's Award in 2005.
