I've built embedded firmware for Cyient's smart energy meters and substation protection systems, including power-state transitions, metering communications, ADC acquisition, power-quality algorithms, and IEC 61850 connectivity.

Previously at Lotus Wireless Technologies, I developed SIL-4 pCode power-management firmware for the Kavach train collision avoidance system. I implemented fail-safe power sequencing, UVLO, FreeRTOS and Embedded Linux concurrency, protocol integration, and verification against IEC 62280 and RDSO specifications.

At Alpha Design Technologies, I contributed to Indian Defence and Aerospace programs including IFF Mk XII, IDEX armored-vehicle tracking, and VHF SDR tactical communications. My work covered C firmware, RF power control, CAN and RS422/RS485 interfaces, GNSS tracking, DSP algorithms, and DO-178C-oriented validation.

I'm comfortable across the full firmware lifecycle—from architecture and coding through hardware debugging, validation, production flashing, and field support—and I'm available immediately for remote roles worldwide.
