About

Embedded/Firmware Engineer at Amazon Ring, working on low-power,battery-operated smart home devices used by millions of customers. I act as a firmware solution architect, owning end-to-end firmware release readiness and feature integration across Ring video doorbell and camera products. My role spans firmware architecture, power optimization, system integration, and cross-team execution. I specialize in low-power embedded firmware, battery life optimization, and system-level debugging on resource-constrained platforms, with strong hands-on experience in embedded C/C++, RTOS, and bare-metal systems. I work closely with hardware, systems, QA, and product teams, driving integration strategy, risk mitigation, and production release. Core Skills: - Low-power firmware & battery optimization - Firmware architecture & release ownership - RTOS & bare-metal systems - Device drivers (SPI, I2C, UART, GPIO, DMA, ADC, PWM, Flash) - Cross-functional technical leadership Previously, I developed driver-level firmware and handled the Battery Management System Firmware (BMS) for EV systems at Ather Energy and built a strong embedded systems and hardware foundation at Philips Domestic Appliances and IFB Industries, working on motor control systems and consumer electronics
