Electrical Engineering Student & Embedded Systems / Robotics Researcher

I build real-time embedded control systems and robots that operate where software meets the physical world — from bare-metal firmware driving hydraulic actuators to AI-assisted perception for autonomous flight.

About

Where hardware meets intelligence

I'm a first-honors Electrical Engineering student at King Fahd University of Petroleum and Minerals (KFUPM), while working across embedded firmware, control systems, and applied robotics research.

I've explored and developed projects in the fields of robotics, autonomous drone systems, closed-loop systems, and machine learning. My specialty is writing bare-metal C for real-time control loops, reverse-engineering undocumented communication protocols, and closing the loop between sensors, actuators, and decision-making software. I'm currently a Research Intern at HKUST developing control firmware for a water-hydraulic soft robotic arm, alongside ongoing undergraduate research at KFUPM spanning assistive robotics.

Additionally, I am currently learning more on PCB design and electroencephalogram (EEG) for assistive robotic control through brain waves.

Research, competitions & leadership

A timeline of research positions, technical leadership roles, and hands-on engineering work.

Research Intern — Soft Robotics & Embedded Control

06/2026 – Present
Hong Kong University of Science and Technology (HKUST) — Summer UG Research ProgramHong Kong
  • Developed bare-metal C firmware (STM32H7) for a water-hydraulic soft robotic arm driving 2 PWM pumps, 5 CAN servo drives, and a Modbus RS485 flow sensor in a real-time loop.
  • Reverse-engineered an undocumented CAN 2.0B protocol with a custom firmware bus sniffer, fixing frame-encoding faults that had left 4 of 5 drives inoperable.
  • Designed an asymmetric-margin tendon synchronization algorithm that eliminated the system's primary mechanical failure mode.
  • Implemented sensorless closed-loop positioning by integrating flow-sensor data against a calibrated volume-to-displacement regression — validated to 3.5 mm mean absolute error (RMSE 4.9 mm, R² = 0.99) across a 315 mm stroke over 10 trials.
  • Built a layered safety system (stall detection, travel limits, pump interlock) halting actuation within 600 ms of a jam.

Design & Assembly Lead

10/2025 – 02/2026
KFUPM Robotics Team — VEX U PushbackDhahran, Saudi Arabia
  • Qualified the team for the VEX U National stage; directed a 14-member sub-team across CAD, fabrication, and integration.
  • Designed and assembled a 22 in. competition robot (AutoCAD) with intake, outtake, and scoring mechanisms driven by motors, flex wheels, and pneumatics.

Undergraduate Researcher — Robotics & Assistive Technology

09/2025 – 05/2026
KFUPM Research and InnovationDhahran, Saudi Arabia
  • Engineering a 16-DOF robotic hand that translates spoken input into ASL fingerspelling across 24 letters of the manual alphabet (excluding the two motion-dependent letters).
  • Built the speech-to-gloss-to-motion pipeline on Jetson Orin Nano with ROS actuator control; designed the full mechanical CAD assembly.

Undergraduate Researcher — Acoustic UAV Detection

05/2025 – 10/2025
KFUPM Telecommunications Research LabDhahran, Saudi Arabia
  • Developed a hybrid acoustic drone-detection pipeline on NVIDIA Jetson Nano with real-time inference at 15–20 FPS.
  • Trained a ResNet acoustic classifier (TensorFlow) to 92% precision; implemented microphone-array Direction-of-Arrival localization with full 360° coverage.
  • First-authored a systematic review of 20+ studies (2018–2024) on acoustic UAV detection.
