Programmable
bench power supply

A Wi-Fi-enabled power supply with constant-voltage and constant-current control. I designed the switching architecture, protection circuits, and isolated feedback, then carried out functional testing and thermal analysis.

motion control

A closed-loop control system for a two-axis robotic arm. I combined STM32F4 firmware, two DC motors, and an MPU6050 motion sensor with PID feedback to improve joint-position and motion tracking.

Hardware Design
Engineer

El Sewedy Electrometer

I contribute to energy-meter platforms manufactured at more than one million units annually and deployed across six countries.

From mixed-signal design and PCB development to debugging and production release, I work with firmware, mechanical, manufacturing, and quality teams to turn engineering requirements into reliable products.

  • Support design transfer across four international manufacturing facilities.
  • Helped reduce hardware development cycles by approximately 20% through reusable circuitry and design standardization.
  • Support component selection, design changes, and hardware verification throughout the product lifecycle.
