Hossam Mamdouh
Embedded Systems Engineer | IoT Developer | PCB Designer
Embedded Systems Engineer with a Bachelor degree in Electronics and Communications Engineering, specializing in Embedded Systems Design, Firmware Development, PCB Design, and IoT Systems. I help clients turn concepts into practical devices with clean implementation, clear communication, and production-minded thinking.
What I Do
Embedded C/C++, assembly, low-level device control, hardware-software integration, debugging, and performance optimization across common microcontroller families.
Sensor acquisition, Wi-Fi connected devices, smart monitoring systems, and control logic for automation, healthcare, environmental, and industrial applications.
Schematic capture, layout, and board optimization using EasyEDA, Altium Designer, KiCad, Eagle, and a workflow designed for prototype-to-production handoff.
Circuit design, simulation, and validation using Proteus, Tinkercad, Fritzing, and Wokwi to reduce risk and iterate faster before hardware build or deployment.
Featured Work
Built around ESP32 and the AD8232 ECG sensor for real-time signal capture, remote health monitoring scenarios, and future cloud-ready expansion.
An ESP32-based control PCB with LCD, alarms, LED indicators, and relay output for monitoring and pump or valve control in real installations.
A glove-based wireless control system using an accelerometer, Arduino Pro Mini, RF communication, motor driving, and obstacle sensing.
Core Tools
AVR, PIC, 8051, STM32, ESP32, ESP8266, Arduino Uno, Nano, Mega, and microprocessor-based systems.
Proteus, Autodesk Tinkercad, and Fritzing.
Smart Systems, Greenhouse Control, Medical Monitoring, Automation, Robotics, and Real-Time Embedded Products.
Why clients hire me
Focused on practical, production-ready solutions and clear milestones.
Comfortable moving across Firmware, Electronics, Simulation, and PCB tasks.
Strong fit for freelance collaboration across Upwork, Freelancer, and direct client projects.
Next Step
I can help with product ideas, proof-of-concept builds, simulation, and production-ready embedded hardware workflows.
