Firmware architect at Lyptus Technologies building secure, low-power Zephyr firmware for ARM Cortex-M wearable medical devices.

India
Message

At Lyptus Technologies, I architect bare-metal and Zephyr RTOS firmware for an nRF54L15 ARM Cortex-M wearable medical SoC, with a focus on ultra-low-power design and performance. I work on OTA updates, BLE Coded PHY, NFC, and capacitive sensor integration, and support board bring-up, testing, and customer releases.

Previously at Schneider Electric, I designed and implemented firmware for 3-phase UPS systems, including event-driven state machines, secure boot, and OTA upgrades. At Infineon Technologies, I developed Qi wireless charging firmware and evaluation kits, and authored the FOD Tuning Guide application note; across my work, I’ve also mentored firmware engineers and contributed to secure embedded systems across power, IoT, wireless, telecom, and automotive domains.
