Ajith Shenoy

Embedded Systems Consultant for Safran Cabin galley systems. Worked on ARINC 812 requirements, manual and automated verification, Codebeamer traceability, and production-hardware bench testing. Rewrote ~50 automated tests, prototyped Python-CAN test automation, identified an ARINC 812 timing non-compliance, and built a Python-CAN HMI simulator to support beverage-chiller processor integration.

Co-Founder / Managing Partner and Embedded Systems Consultant. Led system and hardware architecture, schematic design, supplier/manufacturing coordination, debugging, test, and delivery for cellular IoT products and automotive tools. Delivered Python/DoIP flashing and XCP-unlock tools for Lear test benches and helped bring two nRF52840-based IoT products through production, totaling 285 delivered units.

Systems Engineer in automotive connectivity / telematics. Defined and aligned system requirements for GNSS, eCall, Wi-Fi, cellular, diagnostics, OTA and remote functions; supported vehicle and plant integration using DOORS, CANoe and Python. Led weekly customer systems meetings for ~18 months, proposed the accepted RMII architecture change, built remote mini-HIL setups, and automated flashing/configuration for ~7,000 units.

Embedded Systems Engineer developing Nordic SDK/C++ firmware for connected trackers. Implemented OTA and device-log retrieval, maintained GNSS and TCP/mTLS components, and resolved LTE Cat-M1/NB-IoT connectivity issues. Root-caused an intermittent OTA corruption defect in the receive path, implemented the cache-alignment fix, validated it with ~50 successful post-fix runs, and shipped the fix to production.

Worked on onboard connectivity and A320 pre-delivery test systems spanning system architecture, hardware/software integration, embedded Linux/BSP, suppliers and qualification. Evaluated Wi-Fi, Bluetooth, 4G/LTE, RFID and 6LoWPAN solutions, supported board bring-up and DO-160 testing, and simplified A-Plug ARINC architecture, reducing HI-3210 devices from 6 to 4 and saving ~$400 per aircraft.

Developed aircraft physical-system models and diagnostic concepts using MATLAB, Simulink, Simscape, Stateflow and SimHydraulics. Worked on electrical and hydraulic simulation, generator fault diagnostics, FMECA and fault propagation. Automated FFA JSON generation using Python and built a Cabin predictive-maintenance prototype that led to follow-on development and patented work.

Developed and verified A330/A340 Flight Warning software under DO-178B Level C. Implemented software enhancements, ICD/interface changes and new warning functions using PL/M and x86 assembly. Performed unit testing, requirements/code tracing, integration support and airline issue investigation. Also worked on processor-margin optimization and managed work packages for two subcontractors.

Systems Engineer for avionics GPS/GNSS and transponder products spanning hardware, embedded software, integration and qualification. Designed a Eurofighter GPS-GLONASS receiver, developed ADSP-21489 firmware, debugged a VisualDSP++ loader defect with Analog Devices, and reduced CPU utilization from ~99% to ~40% through memory/DMA architecture improvements. Also supported MIL-810D/MIL-461E qualification and production.
