Staff Software ArchitectGe Healthcare Oct 2004 - May 2024Responsible for server side software architecture of Centricity PACS. Key contributions include updates to architecture and subsystems to reduce tech debt, provide detailed analysis of security vulnerabilities in Centricity PACS software, and modernization of the OS platform to RHEL 6 and RHEL 7, and Java runtime to improve security, scalability, and performance. Current responsibilities include subject matter expertise in DICOM, IHE, HL7, XML, medical image compression, and SMB3. Current skills include Java 8, Eclipse IDE, C/C++, Ansible, Bash, Transact SQL, RHEL 6/7, SAP ASE 15.7, Jenkins, Clearcase and Git. Much of the current work includes prototyping of proposed architectural changes and working with the engineering scrum teams to incorporate them into Centricity PACS server software offering.Previous work included providing multiple scrum teams guidance on SDLC software identification and decomposition and risk management compliance through capture of risk assessment activities as an extension of design FMEA activities. The scrum teams are much better prepared to follow through on these activities using my guidance.

AnalystGoldman Sachs Sep 2000 - Sep 2004New York, New York, Us• Led the development of a market price data distribution infrastructure and related C++ API’s targeted to both Linux and Solaris run time environments and based on TIBCO/Rendezvous multicast middleware. The new infrastructure provides compatibility with an existing 3rd party API the SLK-Hull trading system leases. Low latency under high message loads, lightweight footprint, data and code compatibility, Linux/Solaris run-time, and code ownership were chief goals. Responsible for project planning, and the design and implementation of transport API wrappers for TIBCO/Rendezvous, data marshalling using a visitor pattern, event queuing using a reactor pattern, fault tolerant multithreaded price data cache implemented using POSIX threads and Berkeley DB, and portions of the compatibility layer. -

Lead Software DesignerGe Healthcare Apr 1997 - Oct 1999Chicago, Us• Enhanced PathSpeed PACS (previously Vantage PACS) to provide an enterprise wide view (EView) to both images and examination information. Designed and implement an image transfer server based on the DICOM protocol and proprietary compression algorithms implemented in C++ using STL extensively. The PathSpeed PACS Sybase database tracks where a particular image is located among one or more image file servers in the EView enterprise. Each file server has an associated image transfer server. The image transfer servers collaborate with each other to service requests to copy an image from an image file server to another.

Senior Software EngineerLoral Aerospace - Medical Imaging Systems Sep 1994 - Mar 1996• Researched, designed and implemented a lossless image compression algorithm for the Loral PACS teleradiology application that would sustain real-time throughput at T-1 speeds and provide 3:1 image compression. Customer satisfaction with the teleradiology application improved greatly due to improved performance, productivity and lower switched T-1 data communication costs.

Principle Software EngineerSiemens Healthcare Feb 1991 - Sep 1994Forchheim, DeDesigned and implemented a teleradiology solution integrated with the Siemens/Loral PACS. The teleradiology application moved examination, patient, and medical image data acquired at a remote location to a centralized PACS for archiving, reading, and reporting. Examination reports were sent from the PACS to the remote location upon completion by a radiologist. -
