- Designed, implemented, and customized a Modbus RTU library over UART with DMA reception to control Panasonic AC servo motors and Feetech servo motors, enabling polling of position, torque, and error codes, with robust fault handling.
- Working on a custom STM32 bootloader with Ethernet-based OTA firmware update support, and configuration parameter management in non-volatile memory.
- Worked on STM32H7 and STM32F4 using STM32CubeIDE, including .ioc-based configuration, linker script handling, and firmware debugging.
- Working in the healthcare (pharmaceutical) automation domain, developing embedded firmware for automated pharmacy systems such as dose packers and container sorters, ensuring reliable, precise, and fault-tolerant operation.
- Collaborated closely with hardware, mechanical, QA, and middleware (software) teams to resolve integration issues, debug complex system-level problems, and perform regular functional and regression testing.
- Worked on ADC, PWM, and timer peripherals for motor current sensing, DC motor control, and LED brightness control.
- Integrated and implemented an I/O expander controller library over I2C, handling configuration, read/write operations, and error management for scalable digital I/O expansion.
- Architected a Finite State Machine (FSM)–based motor control framework to ensure structured operation, safe state transitions, and reliable fault recovery.
- Implemented SPI communication with PowerSTEP01 stepper motor drivers, executing internal motion commands, and processing motor feedback through interrupt-driven mechanisms.
- Implemented FreeRTOS on STM32, utilizing tasks, queues, semaphores, interrupts, and DMA to manage concurrent motor control and communication.

- Worked on IoT projects for consumer and utility clients, such as ONGC and GETCO, developing firmware to collect data from energy meters and sensors, and transmit it to remote servers.
- Implemented Modbus protocol over UART to reliably acquire data from energy meters and field devices.
- Worked with the MQTT protocol and Wi-Fi connectivity for secure and efficient data transmission to cloud and remote systems.
- Used preferences, non-volatile storage libraries, to store device configuration, credentials, and runtime parameters.
- Collaborated closely with hardware teams to develop and integrate firmware, debug hardware-firmware issues, and support board bring-up.
- Provided remote technical support to field and support engineers, assisting with on-site issue diagnosis, firmware updates, and system troubleshooting.
- Performed firmware testing and validation to ensure reliability, communication stability, and correct data reporting in field deployments.
