I believe your unique vision shouldn't be limited by off-the-shelf tech. My goal is to bring your ideas to life with custom hardware, perfectly tailored to what you want to achieve — in Berlin and beyond.
As an Embedded Systems Architect and CEO of Datanoise, I create custom electronic solutions for music tech, IoT, and specialized industrial projects. Need a freelance embedded systems engineer or custom hardware consultant in Berlin? Let's connect.
I'm passionate about engineering custom hardware – the kind that doesn't just tick boxes, but actually opens up new possibilities. For me, real innovation comes from tech that's thoughtfully designed for a specific purpose. As an Embedded Systems Architect in Berlin, I'll work with you from the initial concept through to full-scale production, making sure every detail brings your vision to life.
Datanoise is my Berlin-based company where I focus on crafting custom hardware, especially for music technology and IoT. We handle the entire process, from the first spark of an idea to a finished, manufactured product. My main toolkit includes C/C++ for embedded firmware, backed up by Go and Python for solid backend services and tools.
I also have a strong background in industrial protocols (like CANbus, Modbus, and IIO) and designing secure, reliable system architectures, including hardware security. This means I can build specialized hardware for a wide range of needs – from musical instruments and audio gear to IoT devices and industrial controls – all carefully tailored to what you need and built to perform exceptionally.
