Genaro Salazar Ruiz 🛜

Systems-Level Embedded & RF Engineer

A highly driven Electrical Engineer and Master’s candidate in **Wireless Embedded Systems** (UCSD, June 2027), bridging deep academic knowledge in **RF/DSP** with **3+ years of experience** building high-performance, low-level, and low-power systems.

My expertise is concentrated in **optimizing embedded systems for low-power consumption (90%+ savings achieved)**, implementing bare-metal **DSP/Control algorithms (Fixed-Point PLL)**, and developing professional **test automation frameworks (Python/SCPI)** for hardware validation. I am actively seeking roles in **Embedded Systems, (Embedded)RF Engineering, and Low-Power Design**—positions where the bridge between hardware, firmware, and software is critical for deterministic performance.
