• Updated disinfection, descaling, and draining requirements for various galley equipments. • Developed automated test cases for ARINC 812 requirements using the Python-CAN library.

Developed a Python tool for ECU firmware flashing over Ethernet using ISO 14229 (UDS) protocol. Designed, developed, and manufactured two cellular IoT units from concept to field deployment, covering full system architecture, MCU firmware, cloud connectivity, and production. Zephyr RTOS (C++), EG25 modem (AT command handler, asynchronous UART), nRF52 MCU, GPIO/LED handlers, device logging, OTA updates (MCU, modem, and configuration), and end-to-end manufacturing.

-Responsible for the system design of GNSS, Diagnostics, OTA, eCall components. -Coordinated with cross-functional stakeholders (Hardware, Software, DV, and Plant) to resolve issues and implement new requirements. -Conducted on-site debugging of issues at OEM locations. -Developed Python scripts to • test units prior to EOL tester readiness. • flash both MCU and NAD on 7,000 units at customer and engineering locations. • Simulate responses of other ECUs for over-the-air (OTA) tests

• Designed and implemented OTA functionality. • Resolved LTE(4G) driver connection issues reported by end customers, enhancing connectivity stability. • Maintained and upgraded the GNSS driver, Transport stack(TCP/mTLS) and the device logging system. • Developed CMake scripts for automated versioning and efficient packaging of software releases. • Configured and maintained Jenkins pipelines for automated builds and testing.

• Designed and developed a new on-board connectivity system. • Selected modules (WiFi, Bluetooth, 4G-LTE, RFID) based on available I/O options (PCIe, USB, UART, SPI, I2C) • Redesigned ARINC acquisition logic, resulting in a savings of $400 per unit. • Reviewed schematics and layouts created by suppliers. • Led a team of three engineers in board bring-up and BSP activities, Yocto environment setup, uBoot updates, DTS tree modifications, and driver integrations. • Performed qualification tests as per DO-160E

• Simulated the electrical network (using Simulink, Simscape, SimPower) and a basic landing gear architecture of a generic UAV (using SimHydraulics) for the Integrated Vehicle Health Monitoring (IVHM) framework • Performed Failure Mode Effects and Criticality Analysis (FMECA) on aircraft electrical systems. • Created a rapid prototype of a sensor gateway for demonstration during the Cabin Leadership Team visit.

• Developed and verified aviation software in compliance with DO-178B Level C standards, ensuring adherence to safety-critical software lifecycle processes. • Implemented ICD changes (aircraft system bus changes). • Investigated Problem Reports reported by various airlines and internal validation groups. Created work packages, trained and managed subcontractors.

• Designed and developed a new GNSS receiver for the Eurofighter Typhoon • Analyzed software and hardware requirements to architect the system • schematic design, board bring-up • Implemented a software upgrade module. • Reduced the CPU usage by 60% through: o Implementing an overlay manager o Utilizing DMA-based serial communications between DSP and FPGA, replacing slower direct memory reads o Adopting chained DMA instead of UART Rx polling • Debugged bootloader and kernel code, identifying a compiler bug
