Senior Electrical Engineering student at Prince Sultan University, interested in technology, strategy, and digital transformation. I enjoy working on projects that combine technical problem-solving with business impact, especially in areas such as automation, AI, process improvement, and innovation.

Drive-by-wire control system for a high-efficiency vehicle

Replacing the mechanical steering, throttle and brake linkages of the PSU Eco Team’s Urban Concept EV with closed-loop electronic actuation — the prerequisite step before any autonomy can be added. Every subsystem keeps its mechanical path intact as a backup, because the failure modes of a car you can no longer steer are not the kind you design around afterwards. Controllers were modelled and tuned in Simulink, then validated on a bench-top rig before anything went near the vehicle.

433 MHz axial-mode helical antenna

A six-turn helix for the 433 MHz ISM band, with gain and input impedance worked from the Kraus relations and a quarter-wave strip sized and oriented to match the feed. The geometry was drawn to scale, parameterised in Fusion 360 so turn count, spacing and circumference could be swept without redoing the arithmetic, and then built — copper wound on a laser-cut mast.

Jewel of Najd — 1,600 MWac solar PV study

A techno-economic concept for a utility-scale PV plant in the Sudair region, simulated in NREL’s System Advisor Model and carried through to the numbers that decide whether a plant gets built: capital and operating cost, levelised cost of energy, capacity factor, financing assumptions, avoided CO₂ and construction employment. The model was rebuilt several times as the plant was rescaled, which is where the interesting part sat — watching which figures moved linearly with capacity and which stubbornly did not.

Simulation

Evaluated

Narrowband FM transceiver on an ADALM-Pluto

A complete two-metre NBFM link built in MATLAB Simulink and run over an ADALM-Pluto: modulator, demodulator, and the filtering and rate conversion between them. Most of the work was in the signal path rather than the block diagram — FIR filter design, a resampling architecture that holds audio bandwidth without aliasing, and modulation parameters checked against a commercial handheld on the same channel.
