Jose Della Sala

• • Designed and implemented a multithreaded CAN communication stack with kernel-level filtering and automated firmware updates, replacing a legacy single-threaded design and improving system reliability across nationwide deployments

• • Extended the Nyquist CAN architecture to support detachable devices (LED displays, strobes, volume controllers, and next- generation call switches), enabling new products including the Wall Baffle Combo (WBC), Double-Sided Display (DCS01), and Nyquist Volume Controller

• • Built and deployed embedded Linux environments for ARM AM335x hardware, including U-Boot customization, Linux 5.10 kernel builds, and Device Tree overlays via cape detection

• • Led the operating system migration of 23 Nyquist appliances from Debian 8 to Debian 12, ensuring driver compatibility, modernized kernel infrastructure, and full feature parity

• • Performed board bring-up and validation, debugging CAN controllers, DSPs, and HDMI peripherals using oscilloscopes and JTAG

• • Led development and product rollout of the Wall Baffle Combo Speaker, a VoIP endpoint with LED and strobe messaging for visual emergency communication, taking it from prototype to large-scale deployment across thousands of U.S. installations and featured in major AV industry publications

• • Developed a Windows desktop application in C#/.NET using Progress Telerik UI to control and monitor digital radiospectrometers over Ethernet and USB

• • Integrated a proprietary networking DLL to enable full device discovery, command execution, and data acquisition from embedded targets

• • Implemented dynamic UI generation, creating and destroying Windows Forms per connected instrument to support multi- device sessions and synchronized data collection

• • Built interactive visualization modules with zoomable, overlay-enabled charts and live measurement tables for comparative optics analysis

• • Created and deployed a Windows Installer (MSI) distributed to hundreds of systems and added USB camera integration with a dynamic viewing window embedded in the UI

• • Conducted board bring-up and system integration of Xilinx Ultrascale+ FPGA-based avionics radio systems

• • Developed a FreeRTOS/LwIP Ethernet-to-ARINC 429 test appliance, verifying 400+ label definitions and resolving latency defects

• • Authored low-level C++ drivers for FPGA peripherals and custom interfaces

• • Served as bootloader compliance lead, tracing 1,200 requirements in Jama/DOORS, resolving 300 MISRA findings, and passing FAA SOI-2/3 audits with zero major observations

• • Built an automated test environment using RVS, PyATE, and Trace32, reducing regression cycle time across verification benches
