SDE-1 @ JIO · Building the firmware backbone for **AirFiber IDU / Openwifi Devices ** — carrier-grade Wi-Fi at scale.
I live at the intersection of Linux kernel space, embedded systems, and open-source infrastructure. My day-to-day involves writing C daemons, wrangling UCI configs, debugging hostapd race conditions, and pushing PRs upstream to OpenWrt and Zephyr RTOS.
