Principal Software Engineer

Led architecture, design and development of Android Framework for new Android infotainment platform (AOSP migration & customization) as part of Open Automotive Alliance:• Android Application Framework: Designing and implementing functionality in the least intrusive, most maintainable way across Android versions.• Multi-user Support: Providing ongoing support and domain guidance for implementing multi-user functionality across Android OS versions.• OS Migration: Migrating IP to successive new Android OS versions.• Proprietary Phone Integration: Designed and implemented multiple interfaces to proprietary phone hardware, allowing simultaneous use by both stock Android apps and proprietary apps.• XM / Tuner Services: Designing and implementing services used by Android applications.• Permissions: Providing guidance for implementing permissions for proprietary APIs across domains.• Personalization: Focal point for OEM provided service requiring data interfaces to all application and service domains.• SDK: Responsible for development and maintenance of stock and proprietary SDKs.• CTS Automation: Analyzing test failures and automating Android CTS.• Navigation: Designed navigation framework for providing and extending location and sensor data as needed by Android Framework and navigation applications. Designed and implemented custom Android GPS driver.• Ported existing IPC and OS framework IP to Android NDK and AOSP.• Ported existing applications to Android as both AOSP native binaries and Java / NDK applications.• Implemented and improved on advanced routing algorithms for current and next-generation infotainment systems.  Particular focus was on new and changing ecological and economical routing and fuel consumption models.

HARMAN International

Principal Software Engineer - Android Framework Lead

Medical device company specializing in neonatal diagnostic equipment.  Responsible for new product development as well as refactoring existing products.  Worked on multiple products resulting in successful FDA (510k) clearances.Android Application Development for Echo-Screen III• Led development of medical device application running on Android and on custom hardware. • Managed requirements and design for application.• Led design and development of UI for application with touchscreen and LCD on custom hardware.• Designed interface and infrastructure for medical records, device configuration, platform services, licensing and custom analog hardware.• Implemented service-oriented architecture to support users running PC clients, allowing users to control and manage data on the medical device over a network.Android Platform Development for Echo-Screen III• Designed Android / Linux platform and application architecture using Java, C and C++.  • Converted in-house multi-threaded C# state machine libraries to Java.• Developed automated messaging approach that combined documentation and source code development.• Researched modifications to Android LogicPD Board Support Package (BSP) to support custom hardware platform using TI OMAP processor.• Created modular, message-based design consisting of a local client Java application and multiple services and daemons.

Natus Medical

Started and managed Milwaukee branch office in 2003, including a team of 8 engineers as direct reports.  • Led office growth from scratch to 8 engineers by 2008 and annual revenue growth from $60k in 2003 to over $1m by 2008.  • Constructed a common protocol stack for abstracting data in building communications networks.  Defined common data set definition for Modbus, BACnet, and proprietary protocols.  Targeted stack for PC and embedded microcontroller families.• Designed and developed firmware for redundant and distributed system containing 4 microcontrollers for handling sensors, control and user feedback.  Abstracted architecture from hardware, allowing initial implementation to be developed and executed on PCs.  Developed modular inter-processor communication protocol, allowing use of communication libraries in automated test system and PC manufacturing tools.• HIL Tester: Replaced existing hardcoded messaging CAN transceiver-specific testing PC software with a system that dynamically loads CAN message databases and uses CAN transceivers from multiple vendors. Architected and developed replacement application that abstracted CAN transceiver interfaces and removed hardcoded messaging data.  Designed user interface to dynamically render based on the loaded messages.  Implemented abstract CAN transceiver interface so that additional plugins could be created for other CAN transceivers.  • Designed and implemented a proprietary ad-hoc master-slave RS485 protocol for rapid master failure handoff, parallelism and redundancy.  This protocol allowed peer nodes to detect master failure, renegotiate and declare new master node in less than 60 ms.• Developed a digital communications hub allowing over 100 analog controls and sensors on older planes to be used with newer digital cockpit technology.• Architected and developed HIL system simulating normal and abnormal 3-phase power and generator conditions for testing power generator controllers.
