¤ Sep. 2004 to Jun. 2007, Software Engineer, Amazon.com Seattle, WA.

· Extend functionality of the Amazon Data ware house and maintain and operate the in-house developed ETLManager tool for scheduling and running 14000 ETL (Extract Transform and Load) jobs daily serving 2200+ Amazon internal users worldwide across all timezones.

System was designed to support a mix of databases, Oracle, Mysql and Netezza. System run on a 50+ Linux cluster running Redhat Enterprise Edition (3.0). Operations included distribution/escalation of work across diverse teams spread geographically.

Performance tuning of data ware house to achive higher throughput starting at 9000 user jobs to over 14000 user jobs daily. Adding functionality such as introducing a concept of 'Universes' to allow users to focus on queries relating to that 'universe', some examples of universes are 'sales universe', 'order universe' or 'shipment universe'. Extended functionality to allow non-SQL experts create queries using a drag-n-drop technique. The result of this enhancement was easier maintenance of metadata to less than 300KB when the original metadata had grown to over 2MB

¤ Jan. 1999 to Sep. 2004, Principal Engineer, Hughes Network Systems.

Germantown, MD.

· Team lead responsible for architecture and delivery of software to perform synchronization, power control of a high-speed ip over satellite network (Spaceway) with uplink speeds as high as 16MBPS, synchronization steps in the order of a few micro-seconds. The space link segment of this network involved complex algorithms for power control to regulate power with a half (0.5) dBm. An in-house developed ASIC was used for this purpose. The entire system ran on multiple PowerPC's, each performing a specific task like Bandwidth control, power control and synchronization.

· Support sub-system/system integration and verification for ICD (Interface Control Document) compliance.

· Design, develop and document synchronization software between the Satellite and Ground Station for a Cell phone over satellite system. Used Shaler-Mellor methodology for software development.

· The telephone system supported dual mode handsets which could change between satellite mode and GSM.
