Phillip V.

PhD signal-processing engineer (IEEE Senior Member) with 15+ years building the hard parts of radar, navigation, and perception systems — the work most freelancers can't take on. On Upwork I've delivered phased-array antenna systems, mmWave/radar pipelines, and GNC software, including a 520-hour phased-array build rated 5.0 ("Doctoral-level understanding of antenna science"). Core expertise: • Radar & RF DSP — phased arrays, AESA, mmWave, micro-Doppler, SAR, real-time FPGA signal processing • Navigation & sensor fusion — GNSS receivers (Starfire), inertial navigation, Kalman/EKF tracking, multi-sensor (radar/lidar/camera) fusion for L3/L4 autonomy • Machine learning for sensors — radar point-cloud clustering/classification, CNN micro-Doppler human-behavior detection, interference mitigation via ML, CUDA acceleration Tools: MATLAB, Python, C++, TensorFlow, HFSS, FEKO, CST, ADS, Altium, Cadence. Prior: Senior Staff Engineer at John Deere (GNC/GNSS), Senior Perception Engineer at Aptiv (BMW fusion tracker). PhD in radar systems, robotics & computer vision. If your project needs someone who can go from the RF front-end through the estimation math to production code, that's exactly my lane.
