Sadat R.

I develop embedded electronic systems that combine Digital Signal Processing, power electronics, circuit and PCB design, firmware, motor control, and machine learning—from low-frequency audio and vibration analysis, digital filters, FFT, feature extraction, and pattern recognition to inverters, converters, motor drivers, and real-time microcontroller implementation. My expertise includes: • Embedded systems development using STM32, ESP32, AVR, nRF52, and Arduino-compatible platforms • Low-frequency audio and vibration signal processing • IIR/FIR digital filter design, FFT analysis, cross-correlation, feature extraction, and noise reduction • Pattern recognition, anomaly detection, condition monitoring, and predictive maintenance • Machine-learning model development using neural networks and support vector machines • Power electronics, including inverters, DC-DC converters, battery and supercapacitor chargers, and BMS • BLDC, stepper, servo, and closed-loop motor-control systems • Analog circuit design, sensor interfacing, data acquisition, schematic design, and PCB layout I focus on delivering reliable, practical, and manufacturable solutions with clear communication and thorough documentation.
