Peripheral driver development and pre-silicon validation for automotive-grade SoCs — CAN, LIN, and ADC on RISC-V and TriCore architectures.

• Module owner for CAN, LIN, and ADC drivers on a RISC-V automotive SoC — architecture design, test specification, req-to-test traceability, and customer demonstrators; concurrent bug triage on legacy TriCore Aurix.
• Bare-metal Bosch CANXS (Classic/FD/XL) driver and CAN Routing Accelerator with interrupt-triggered DMA for zero-CPU message routing; LIN 2.x master/slave with sync break, PID parity, classic/enhanced checksum, and diagnostic frames.
• SAR ADC (12-bit) and Low-Power SAR ADC (8-bit) — channel mux, S&H timing, multi-level gain/offset calibration.
• C directed tests for corner cases (FIFO overflow, bus-off recovery, ADC saturation) via ASTER, validated on Synopsys Virtual Prototype; C driver APIs ported as UVM stimulus over DPI-C for block and cluster-level RTL verification.
• Python/LLM agentic pipeline for autonomous VP and silicon fault isolation; extended to MISRA triage and HW-spec-driven test case generation.

Embedded software for wireless audio products (earbuds/headsets) on Qualcomm's audio SoC — spanning DSP configuration, XPAN BT/WiFi coexistence, and Bluetooth stack development.

• Migrated Active Noise Cancellation firmware to a new Qualcomm audio platform — redesigned the DSP processing pipeline per ANC use case and brought up audio graphs through codec and amplifier hardware.
• Worked on XPAN — BT/WiFi coexistence on a shared 2.4 GHz radio. Clock synchronisation across BT and WiFi for seamless audio handoff, TCP/UDP control/data plane, and RSSI-based radio switching at the driver level.
• Implemented multipoint Bluetooth allowing simultaneous connections to multiple host devices, with automatic priority switching between music and calls and clean handoff between active use cases.

Firmware and DSP development for medical-grade audio devices on STM32 ARM Cortex-M4 — from bare-metal bring-up to real-time signal processing.

• Peripheral bring-up — ADC, DAC, SPI, I2S, DMA, Timers, and Interrupts on STM32; FreeRTOS for concurrent task management.
• DSP pipeline using ARM CMSIS — Biquad filter implementation, Chebyshev and Butterworth filter design, FFT, Wavelet Transform, and FIFO-based audio buffering.
• Built a proof-of-concept acoustic beamforming system using a microphone array.
