• Implementing and optimizing deep learning models on ARM Cortex M based edge devices, utilizing TensorFlow Lite, micro NPUs and inhouse ML compiler
• Implemented new features, proposed changes in the standards and maintained the MAC and Network Layer of DECT wireless stack (an ETSI Standard implemented in C). These features include :
• Automatic Dynamic Power Control : a novel master-slave algorithm to set the TX power of two connected nodes based on RSSI and link quality parameters to dynamically use less power when nodes are close and more power when nodes are far.
• RF Ping : an extremely lightweight replacement to existing ping-pong feature in our DECT implementation
• Paging burst : for ULE devices that only wake up once a while,
• Emergency link setup and location triangulation using RSSI
• The wireless stack runs on coin-cell capable Cortex M33 based chip, with lots of power and performance optimizations.

• Joined at early stage and got to work on a unique fixed wing Solar Powered UAV
• Designed, developed (in C++) and tested a mission-critical RTOS based Data Acquisition System, running on ARM Cortex A, that diagnoses and commands the on-board avionics. Created custom protocols for interaction between various CAN (battery management systems), UART (autopilot) and wireless-ly connected nodes (ground station) that constituted the on board avionics system. This DAQ could remotely be connected to multiple end-points on the ground-station.
• I also designed and developed, using QT Designer and Python, a multi-tab GUI that processes real-time data received from DAQ and displays it for intelligent system health monitoring and control.
• Implemented custom applications over C++ based open source flight management stack (PX4).

Jun 2019 – Nov 2020 · 1 yr 5 mos · Gurugram, Haryana, India

• Designed and developed a linux based microservice using C++, ROS, REST APIs and Docker, facilitating diagnostics and control of embedded targets connected over CAN and LIN bus
• Developed a feature rich bootloader and companion python based server application for ARM Cortex-M and Cortex-A products supporting dual-application mode, corrupt-application detection and user authentication
• Profiled, analyzed and ported bare-metal legacy code running on ARM Cortex M devices to propriety FreeRTOS based framework utilizing modern design paradigms

• Simulated (in PSIM) and implemented a digital control scheme for ‘Phase Shifted Full Bridge DC-DC Converter’ (48V-12V stepdown) on TI Piccolo C2000, effectively replacing analog switching logic.

Jun 2017 – Jul 2017 · 1 mo · Bangalore, India

• Worked on ‘Relative Attitude and Position Estimation of LEO Spacecraft in Formation using Line of Sight Measurements’.
• Implemented, on the on-board-computer, a full-state Kalman Filter and Controller in state-space without directly using target satellite dynamics data.

• Led a team of 5 members that devised, simulated and implemented orientation estimation and control algorithms like Extended Kalman Filter and sliding mode controller for de-tumbling, target-pointing and ground station tracking for a 3U hyperspectral-imaging nanosatellite
• Selected and interfaced actuators and sensors, ported algorithm implementations to the on-board computer and built test-beds in collaboration with other subsystem teams
