Designed and developed for retrieving information from medical devices and storing the information in an offline database. Also developed database and web-driven PC-based applications.

Developed hardware test control and sequencing software for manufacturing line processes and verification.

Designed and developed embedded system software for a state-of-the-art, minimally invasive therapeutic medical device, aimed at improving women's health. Tasks included software system design and implementation, integration to imaging subsystems, configuration management, build and release, testing and verification. Included software development at all levels of system control, business logic, application and user interface in C++, C# and .Net environments running on Windows XP.

Designed and Developed a software interface to integrate third-party medical systems to Hansen Medical devices.

Defined and Developed Software Process for the development of a state-of-the-art medical device. Task included defining and writing Software Operating Procedure documents such as a Software Development, Software Testing, Configuration Management, etc., as well as defining and writing a Software Development Plan (SDP). Defined Software Specification Process Document Templates for Software Architecture, Software Requirements, Software Design, Software Test, etc.

Designed and Developed application and control software to support the manufacturing process for a medical ultrasound system. Software system consisted of an intuitive user interface, application and control software for configuring, programming and controlling industry-standard Modbus devices. During program execution software also logged output and graphed results in real-time.

Task included defining and writing Software Operating Procedure documents such as a Software Development, Software Testing, Configuration Management, etc., as well as defining and writing a Software Development Plan (SDP). Defined Software Specification Process Document Templates for Software Architecture, Software Requirements, Software Design, Software Test, etc.

Selected and Deployed Configuration Management System (SubVersion) for existing and new codebases and process documents. Implemented hook scripts for selected events and authored User Guide for basic and advanced operations and defined a Branching Strategy.

Redesigned and re-implemented monitoring and control software for handling embedded devices such as fans, power supplies and other devices. Converted source code from unmanaged C++ to C# and managed C++. Re-factored in to layers and components for reuse including use by unmanaged clients. Also hid transport layer details and mechanisms and improved performance using .Net Windows Communication Foundation.

Re-architected prototype software system for an ultrasound device based on PureMVC Model-View-Controller framework and employing .Net where beneficial to the system. Included separation of GUI and graphics views, breaking the software system in to layers of responsibilities and employing multiple views and controllers.

Siemens Medical Solutions

Software Architect for next generation medical ultrasound system as well as Technical Lead for off-shore development in India and Slovakia.

Designed and implemented a subsystem control (hardware) abstraction layer in a large-scale object oriented data-driven system to allow for plug-and-play architecture of the application, and resulting in large-scale code re-use for newly developed hardware platforms.

Designed and implemented a complete error handling and recovery system for a medical ultrasound machine, including watchdog timers, exception handling, and system shutdown mechanisms (for patient safety), capable of saving system state information such as stack traces and core files. Also developed a logging mechanism to archive such information for remote retrieval and post-mortem analysis.

Led an inter-disciplinary team of software engineers and product development marketing personnel to address, and resolve, performance and other user interface issues, resulting in greater user acceptance and market penetration.

Assisted in the development of a software automated test environment, capable of running both on the target and in a simulation environment, for full regression test capabilities, thereby reducing the cost of defect resolution by identifying such defects early in the development cycle.

Led an inter-disciplinary team in the design and implementation of a system in which ultrasound imaging parameters, needed to set up machine hardware, were removed from in-line software code and moved to an on-line relational database, thereby reducing on-going maintenance problems, as well as allowing image analysis engineers to specify, and see the results of changing, imaging parameters in real-time.

Actively participated on a team chartered to define, and put into affect, guidelines for software engineering standards and processes organization wide, for on going, and future, development in line with current industry accepted software engineering methodologies and practices.

Wrote test application software and VXI/VME subsystem interface software for production acceptance testing, equipment verification, and countdown procedure for a commercial launch vehicle, which included multi-threaded application programming, inter-process communication, critical-section handling, and graphical user interface methods in a real-time, fail-safe system.
