Hossam Mamdouh
Services
I support clients who need Embedded Systems Firmware, Electronics Design, PCB Design, Circuit Design & Simulation, or a complete Embedded System path from Concept to Tested Prototype.
Embedded C/C++, Assembly, Peripheral Interfacing, Control Logic, Debugging, Optimization, and Firmware Architecture for Custom Boards and Standard Development Platforms.
Schematic Capture, Component Selection, Routing, Layout Review, and Boards Built for Functionality, Serviceability, and Cleaner Manufacturing Handoff.
Design and development of connected systems using ESP32, ESP8266, or Raspberry Pi for Real-Time Sensing, Control, Automation, and Remote Monitoring.
Before hardware build or deployment, I validate system ideas using simulation tools to reduce risk, verify behavior, and tighten client feedback loops.
Typical Engagements
We define requirements, select hardware architecture, create firmware structure, then move into testing, iteration, and validation.
For projects that already exist, I can audit firmware behavior, redesign a PCB section, refine communication logic, or stabilize a prototype.
For early-stage ideas, I can build a proof of concept in simulation to test the logic and give you a clearer path before fabrication.
Available for platform-based collaboration through Upwork and Freelancer as well as direct outreach through LinkedIn.
