PROFESSIONAL EXPERIENCE

Confidential, Boulder, CO

Senior Software Engineer

Responsibilities:

• Created and tuned video pipeline using gstreamer i.MX6 and internally developed elements, bridging RTSP h.264 and MJPEG to USB; increased performance by mapping USB buffers to user space (zero copy) and replacing gstreamer pipeline with original code written to the MjpEG RFC; leveraged wireshark, Python pcap libraries, and Beagle USB analyzer to develop algorithms and characterize performance
• Assigned responsibility for bringing up i.MX6 device produced by ODM; developed and documented functional verifi­cation tests which were used to mentor an offsite SQA engineer; validated subsequent hardware revisions and worked with foreign ODM to solve issues, and provided functional test definitions for inclusion in SQA audit testing

Confidential, Boulder, CO

Staff Engineer

Responsibilities:

• Worked independently to port mobile platform memory protection driver to server firmware; designed and implemented console message logging including per CPU logs; traveled to silicon bring up and successfully validated image features ahead of schedule; modified ARM firmware interrupt driver to enable ISR registration, support proprietary interrupt sources, and define their handlers
• Tasked with owning the trusted firmware image for server upon arrival; demonstrated technical expertise in supporting contributors to code base and approving submissions; developed a Windows build environment, documented on an inter­nal wiki and supported developer team; migrated code base from git to Perforce and internal tools with minimal supervi­sion
• Delivered firmware releases to meet the project schedule often working outside of standard business hours to ensure on time delivery; defined and documented the firmware test process and trained test team members in its execution; respon­sible for verifying legal scans, providing release notes, integrating late feature deliveries, and providing patches for fail­ures found during test to meet project deadlines

Confidential, Beaverton, OR

Senior System Software Engineer

Responsibilities:

• Involved in silicon and board bring-up for Tegra based mobile platforms, booting Linux, Android, Chrome, and Win­dows RT; modified u-boot source code and integrated memory config and device tree files for bring up; resolved Lauter- bach JTAG debugger setup issues and provided reference material on internal wiki; debugged code flashing and boot­loader issues, including I2C errors and board straps; worked with teams across the country and India during bring-up to provide software patches, verify software fixes, and participate in the bug process
• Wrote test scripts in bash, Perl, Python, and proprietary scripting environment for functional and validation testing; de­veloped manufacturing tests used by overseas contract manufacturer to exercise I/O, stress CPU cores, and exercise GPU; configured DAQ and ran partner provided power measurement tests; independently ported diagnostics kernel envi­ronment to support new platforms, and worked with offsite developers to update and validate their diagnostics code
• Integrated audio codecs, cameras, temperature sensors, wifi, touch, and display drivers for ARM embedded platforms; ported Linux power management controller (PMIC) driver from third party vendor to help validate silicon and prepare for platform bringup; modified board files and device tree files to configure GPIOs, voltage regulators, and pinmux

Confidential, Wilsonville, OR

Senior Software Engineer

Responsibilities:

• Developed a comprehensive suite of power on self-tests for an A3 solid ink printer; worked with electrical engineers and HW specs to access in-system measurement capabilities via an FPGA register interface; validated test designs with statis­tical characterization, by building test boards for fault insertion, and confirming device behavior with test equipment; supported test, manufacturing, service, and failure analysis teams at internal and customer sites
• Developed the software architecture for front panel service diagnostics on multiple solid ink printers; leveraged object oriented design to encapsulate process and memory management, messaging, and graceful exit; redesigned diagnostics framework to simplify the integration of tests developed by other team members and leverage features of the core design
• Developed image analysis software for printer test patterns; created reference images using PostScript to verify software and provide research scientists with inputs for printer simulation tools; automated dispatch of the tool to analyze scanned images, log the analysis results, and catch test errors and send email alerts
