Hardware Design
From first schematic to production-ready PCB, with an eye on signal integrity, EMC, and manufacturability.
Hi, I'm
Fawzi Fansa
Inventor. Builder. Entrepreneur. Embedded systems. Traveller. Hiker. Curious mind.
I turn complex problems into working electronics.
Founder · Fusion Sensorik & Messtechnik GmbH
About
A decade at the intersection of hardware and software.
I've spent over ten years designing electronics that don't get seen — the kind that go inside industrial machines, sensors, and systems built to run for years without failure.
I started in Cairo, studied embedded systems at TU Chemnitz, and have since worked across Germany alongside international research stints at INSA Lyon, Rome, and NC State. In 2025, I founded Fusion Sensorik & Messtechnik GmbH.
I work best at the full stack of a hardware product: from schematic to PCB layout, from bare-metal firmware to the tooling that runs on a production line. I take ownership of problems — not just slices of them.
Expertise
What I build with.
Ten years of working across the full hardware stack — from blank schematic to certified product.
Firmware Development
Bare-metal C for resource-constrained systems. Clean, efficient, and built to run for years.
Software Tools
C# desktop tooling for production lines — calibration, flashing, logging, and test automation.
Industrial Protocols
Deep experience integrating devices into real industrial networks across a wide range of standards.
Microcontrollers
Hands-on with a broad range of MCU families across different architectures and peripheral sets.
Prototype to Production
I take products through the full journey — from early prototype to certified, manufacturable series.
Services
How I can help.
Available for project-based engagements, long-term contracts, and consulting retainers.
-
Freelance Consulting
Architecture reviews, technical audits, and feasibility studies. I help teams make better decisions before they build — and fix expensive ones after.
-
Hardware Design & Redesign
Full PCB design from schematic to layout, or redesign of existing hardware for improved reliability, cost reduction, or modernisation.
-
Firmware Development
Bare-metal or RTOS-based firmware in C/C++. Peripheral drivers, communication stacks, bootloaders, and production-ready device software.
-
Prototype to Production
I take early-stage prototypes through DFM, EMC/IP certification, and the full transition to manufacturable, certified series hardware.
-
Component Replacement & Legacy Redesign
Replace obsolete or end-of-life components, redesign legacy boards, or port existing firmware to new silicon — without starting from scratch.
Portfolio
Selected work.
A cross-section of projects from the past decade — hardware, firmware, and the tooling that connects them.
