abdelRhman Hamdy

Versatile Embedded Systems and PCB Design Engineer with over +1 years of experience bridging the gap between hardware layout and firmware development. Specialized in high-voltage (HV) layouts, power electronics simulation, and bare-metal peripheral driver development. Proven track record in enforcing IPC-2221B creepage/clearance safety rules while writing robust, real-time C/C++ firmware.

Expert in full-lifecycle product development, from MATLAB/SPICE simulation to schematic capture, high-speed layout, DFM optimization, and hands-on hardware/software debugging.

Hardware & Firmware Engineer

55W Production-Ready Flyback Power Supply (SMPS)

• Engineered a robust, highly efficient 55W Switched-Mode Power Supply (SMPS) utilizing a Flyback topology optimized for tight load regulation and ultra-low noise.
• Prepared complete, error-free fabrication packages (Gerber X2, BOM, centroid data) that completely eliminated manufacturing and assembly flags during pilot production.
• Conducted thermal profiling and EMI/EMC mitigation to meet industrial safety and noise standards before full-scale commercial release.

Hardware/Firmware Researcher

10kW Uninterruptible Power Supply (UPS) Development

• Spearheaded the research and end-to-end development of a high-power 10kW UPS system.
• Engineered multiple specialized PCBs including the Main Power Board (heavy copper, high-current paths), Control Board (high-speed routing, noise-isolated digital logic), and Communication Card.
• Mapped and verified complex, continuous control loops onto hardware, matching simulated loop stabilities to real-world power electronic stages. Implemented sensor signal conditioning by applying a 1.65V offset for the operational amplifiers to optimize control loop accuracy.

Hardware/Firmware/PCB Researcher

10kW On-Grid Solar Inverter Development

• Managed the end-to-end electrical design and architecture for a 10kW grid-tied solar inverter.
• Developed the high-voltage, high-current power board alongside high-speed control boards, optimizing component placement for thermal management and isolation tracking.
• Applied IPC-2221B safety metrics to safely manage high-current paths, preventing high-voltage tracking and electrical arcing under high-stress operation.

Lead Developer

Graduation Project: V2V Cooperative Adaptive Cruise Control

• Managed the full lifecycle of hardware and software development, from component selection and schematic capture to firmware deployment and final fabrication.
• Designed and validated a Hamming error-correction circuit for linear codes, capable of detecting 1-bit and 2-bit errors.
• Designed efficient charging circuits and power management systems for battery-operated devices and wrote software including the charge algorithms for Li-ion batteries.

Maintenance and Installation Engineer at SUN Power

• Repaired and installed solar inverters, managing more than 500KW of installed energy.

Electronics & Hardware Designer at Robocon Menouf

• Executed various hardware designs for competitive robotics, focusing on high-reliability PCB layouts and real-time processing.

R&D Engineer at APEARC Power Electronics LAB

• Conducted research and development tasks for advanced power electronics applications.
