I am a Software/Firmware Engineer with 14+ years of experience bridging the gap between hardware constraints and user experience. I specialize in system optimization, embedded systems (bare-metal to Linux), and scalable backends.

Highlights:

- Firmware: Yocto, Zephyr, Linux, FreeRTOS, BLE, DSP, ARM/MIPS/x86.

- Backend/Infra: AWS (CloudFormation, IoT), Elixir/Phoenix, CI/CD pipelines.

- Recent impact: Owned the full audio pipeline at Limitless AI (from firmware audio codec to backend storage) and optimized audio playback latency to <800 ms at p99. At R-Zero, reduced the firmware flashing step by 10 minutes per unit on the manufacturing line.

- Experience: Limitless AI (Wearable), SunPower (Energy), and R-Zero (IoT Health).

Comfortable owning the stack end-to-end—from low-level drivers and real-time firmware to backend ingestion, cloud services, and operations. Strong recommendations available from leads at my last 3 projects.

Open to consulting or full-time. Happy to hop on a call to review your architecture or discuss optimization bottlenecks.
