At Bluefin, I was responsible for designing, developing, and maintaining software for the Removable Data Storage Module (RDSM)• Designed camera control software to configure and control an Ethernet connected camera (Blackfly S) • Implemented GenICam standard interface for interoperability with future cameras• Developed drivers to read pressure, temperature, and humidity sensors over the I2C bus • Created I2C base class and derived classes for specific devices• Designed software to monitor sensors and take appropriate action if any values are out of range• Configured Debian Linux for vehicle and created a documented, repeatable installation procedure • Includes NFS, SMB, PTP, SSH, FTP, Avahi, systemd init scripts• Wrote software design documents, presented at design reviews, and participated in all steps of the design process• Collaborated with engineers from other disciplines (electrical, mechanical, systems) to ensure products meet requirements• Participated in the hiring process and mentored new developers and co-ops

• Reverse-engineered compiled C and C++ code to discover security vulnerabilities• Analyzed CAN Bus traffic and fuzzed the CAN Bus to discover security vulnerabilities• Wrote assembly, C, C++, Python, and shell scripts to exploit vulnerabilities• Designed and created a framework for fuzzing and exploitation of the CAN Bus using SocketCAN in Linux• Shared this framework with coworkers to speed the process of vulnerability research and exploit creation• Reverse-engineered a proprietary filesystem and wrote code to parse and extract files• Wrote PowerPC code to interface with and spoof sensors• Developed embedded MSP430 software for an internal tool to extend functionality• Physically disassembled devices; Used oscilloscopes and logic analyzers to aid analysis• Used JTAG to single-step code, examine register values, dump RAM, and generally aid in reverse-engineering• Analyzed cryptographic algorithms to find weaknesses in either the algorithm itself or the implementation• Received two 'Outstanding Performance Awards' for exemplary contributions to time-critical projects• Lead a team at the 'Battelle CyberAuto Challenge' camp to teach students about automotive cyber security• Attended conferences to stay current with technology trends: Defcon, BlackHat, SANS, Escar, TU-Automotive

• Developed and maintained chip drivers and higher-level code for Carrier Ethernet Switch Routers• Wrote drivers in C++ to interface with external devices as well as custom FPGA chips on routers• Enabled interrupts on XFPs to reduce I2C processor utilization• Debugged and wrote code to deal with file corruption problems caused by RCP switchovers• Re-engineered counter file code to fix many legacy bugs• Found and eliminated thread locking and synchronization issues• Prepared and deployed emergency patch for large customer, stopping frequent crashes caused by a malfunctioning FPGA• Documented work through comments and software design documents
