Work Experience
Senior Staff Software Engineer
2016 - 2020
Draeger Medical, Inc.
- Led a team in the design and development of a semi-real-time software protocol, associated SDK and related outputs, and software framework to enable third parties and in-house smart sensor devices to interface with a proprietary patient monitor.
- Contributed to and owned technical designs for the overall protocol and library, time synchronization, secure boot (and associated workflow), software updates, and a framework for automated protocol conformance (and other) testing using Python.
- Contributed to and owned technical designs for a system for multi-platform runtime and development environment for smart sensor devices and systems for automated unit/integration/system tests.
- Initiated the codebase (application and kernel) and the development and build environment for the next-generation patient monitoring platform using experience and assets from the previous project.
- Designed and developed feasibility tests (software and hardware) for the feasibility of USB as a real-time and robust protocol layer (for our system context).
- Traveled or worked on-site with global third-party smart sensor manufacturers to “kick start” relationships and technical progress.
- Pushed for the consolidation of multiprocessor system architecture (successfully) and prototyped the feasibility of the merging of the software.
- Influenced choice of the main processor via GPU/CPU performance testing with intensive Qt Quick/QML GUI software simulation.
- Brought “up to speed” and oversaw a team of three external contractors building an in-house smart sensor device. Mentored new team members and three interns (consecutively).

Staff Software Engineer
2010 - 2016
Draeger Medical, Inc.
- Led a team of approximately 35 software engineers across four sites (local, Shanghai, Russia, and Germany) as the software architect for a new patient monitor project.
- Created patient monitor software architecture involving integration strategies for new and legacy components, e.g. moving to a new hardware platform, new operating system, new Qt-based GUI, and integrating modern framework and field service modules.
- Designed IEC 62304 compliance strategy, including design document template/organizational structure and linkages to system/subsystem requirements.
- Led various local and remote patient monitoring embedded software teams (4-6 developers), including teams in Bangalore, India.
- Led technical review for new company-wide monitoring and ventilation/anesthesia system strategy, currently under development, through system architecture review process.
- Won an innovation award and filed a patent disclosure for patient data visualization prototype.

Senior Software Engineer
2007 - 2010
Draeger Medical, Inc.
- Initiated next-generation patient monitor codebase by migrating legacy build system and codebase from Sun/RCM to Windows/ClearCase.
- Designed and developed a subsystem and network protocol for collecting and documenting fluid intake data from infusion pumps.
- Filed patent disclosure for a system for scheduling patient medications and other nursing tasks in web-based charting application.
- Initiated and developed the project’s automated build and test infrastructure.
- Represented the software team at onsite hospital visits and clinical trials in Spain, Germany, and the UK. Helped bring customer feedback into the product, a web-based medical charting system with interfaces to the proprietary monitoring network.
Technologies: C++, HTML, JavaScript, SQL, ASP.NET, Unit Testing, C#, System Architecture
Software Engineer II
2004 - 2007
Draeger Medical, Inc.
- Initiated a move from JavaScript/ASP to C#/ASP.NET/AJAX and created a common user interface framework to improve the existing infrastructure.
- Re-designed the main back-end service (C++) and added support for data collection from multiple monitoring devices per patient.
- Integrated Windows authentication for user logins, privilege management, etc.
Technologies: COM, Microsoft Foundation Classes (MFC), Microsoft Foundation Class (MFC) Library, Ajax, C++, SQL, HTML, C#, ASP.NET, Active Server Pages (ASP), JavaScript
