Shamanth Poojary

Embedded Firmware Engineer specializing in bare-metal and RTOS-based firmware development in Embedded C/C++ on ARM Cortex-M platforms, including STM32, ESP32, and Nordic nRF5. Develops low-level peripheral drivers (GPIO, I2C, SPI, UART), hardware abstraction layers, and LVGL-based embedded GUIs; owns board bring-up, firmware debugging, and hardware validation using JTAG/SWD, GDB, logic analyzers, and oscilloscopes. Currently developing TWS earbuds firmware on RTX5 RTOS with Bluetooth Classic and BLE (A2DP, HFP, SPP, GATT), with additional depth in Embedded Linux, Linux device drivers, and Yocto.

Firmware Engineer - MIVI

(2026-06)

• Develop and debug TWS earbuds firmware in Embedded C on an RTX5 RTOS-based SoC platform, covering audio streaming, host connectivity and data communication.
• Implemented an embedded audio pipeline for TWS earbuds, integrating SPP-based audio streaming for Android and GATT-based audio streaming for iOS to support both mobile platforms.
• Debug and resolve firmware and connectivity issues across the Bluetooth and audio data paths, isolating faults between protocol handling, audio streaming and platform-specific behavior on Android and iOS.
