Developed for the Agent Services component of Db2 z/OS which involves the creation, synchronization, and overall management of application and system agents that run in Db2.

Diagnosed on a daily basis synchronization issues that led to hung threads, entire system hangs, data corruption and Db2 crashes. Designed solutions that eased the race conditions and improved recovery, all without impacting performance.

Developed web APIs and front end UI for various Logistics applications, used for vehicle shipment building and vehicle delivery tracking among others.

Designed and implemented UNICODE and ASCII support for the ODBC database driver, making it available for the vast majority of products that do not use IBM specific character encoding.
