Mustapha S.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I design and implement Digital Signal Processing (DSP) algorithms, Software-Defined Radio (SDR) receivers, and RF systems using MATLAB, C++, Python, and GNU Radio. I help clients develop reliable solutions for wireless communications, spectrum monitoring, radar sensing, and real-time signal processing. Let's discuss your engineering project ! CORE ENGINEERING SERVICES • SDR Receiver Design & Implementation: Digital downconversion, filtering, resampling, AGC, synchronization, equalization, adaptive squelch, interference mitigation, demodulation, and real-time DSP. • RF Spectrum Monitoring: Wideband and multichannel monitoring, signal detection, classification, decoding, and interference analysis. • Radar Signal Processing: Passive and active radar, Doppler processing, beamforming, detection, localization, tracking, and contactless vital-sign estimation. • RF Front-End Architecture & Design: Component selection, cascaded gain/noise figure, linearity, sensitivity, dynamic range, phase noise, and frequency planning. • Advanced DSP Algorithm Development: Robust, nonlinear, adaptive, cyclostationary, and space-time signal processing; spectral analysis; statistical detection and estimation; biomedical applications. • Simulation & Implementation: MATLAB/Simulink modeling, C/C++ development, Python prototyping, and FPGA/Verilog-oriented DSP.
