Hardware Design
From circuit concept and component selection to production-ready PCBs, with a focus 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.
For more than ten years, I've been building electronics that rarely get seen, but are expected to work every time: embedded systems inside industrial machines, measurement equipment, sensors, and products designed for years of reliable operation.
My path started in Cairo and took me to Germany, where I studied Embedded Systems at TU Chemnitz before working across embedded hardware, firmware, measurement technology, and industrial product development. Along the way, I gained international research experience at INSA Lyon, in Rome, and at NC State. In 2022, I founded Fusion Sensorik & Messtechnik GmbH.
What I enjoy most is engineering the whole system. I can move from an analog circuit or sensor interface to the PCB, then into the microcontroller firmware, communication protocols, PC software, test equipment, and production tooling needed to turn it into a working product.
That breadth also shapes how I approach problems. I don't like stopping at the boundary between hardware and software. If a measurement is wrong, a device is unstable, or a product isn't ready for production, I want to understand why and follow the problem through the entire system until it works.
Expertise
Across the embedded stack.
Hardware, firmware, software and system integration — from first prototype to production.
Firmware Development
Embedded C/C++ for resource-constrained systems — from drivers and real-time control to bootloaders and communication stacks.
Software Tools
Desktop applications and engineering tools for device configuration, diagnostics, calibration, testing and production.
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 we can work together.
Available for project-based development, long-term engineering support, and technical consulting.
-
Technical Consulting
Architecture reviews, technical assessments, feasibility studies, and troubleshooting across hardware and firmware. I help teams make sound engineering decisions before they build — and solve difficult problems when things don’t behave as expected.
-
New Product Development
You have a product or concept that needs to become working hardware. I can take responsibility for substantial parts of the development, from architecture and electronics through firmware, integration and verification.
-
Development Support
Your engineering team needs additional capacity or specific embedded expertise. I can join an existing development, take ownership of defined work packages, and work directly with your engineers.
-
Prototype to Production
Taking embedded products from working prototype toward production — including verification, EMC preparation, production testing, DFM, documentation, and series transition.
-
Obsolescence & Legacy Redesign
Replacing obsolete or end-of-life components, redesigning existing electronics, and porting firmware to new hardware while preserving as much of the proven system as possible.
Portfolio
Selected work.
A cross-section of projects from the past decade — hardware, firmware, and the tooling that connects them.
Production Flashing, Parameterization & QA Platform
C# / WPF production software built from scratch to control firmware flashing and updates, order-specific parameterization, guided QA, reporting and traceability across an entire controller portfolio.
