About me
Kai Chmieleffski
Between your idea and functional hardware, there is no project manager, no subcontractor, no misunderstanding. When you work with me, you work directly with the engineer. I develop electronics that I would use myself. Hardware that I put my name on — and mean what I sign.

"To understand what makes a good engineer, one must understand what drives them. We have a natural curiosity to experience how the things around us work.
We see a task and want to solve it, only then are we satisfied.
A solved problem gives us similar emotions to those a nurse might feel - Only: They get a smile, we get a blinking LED."
Person
An engineer you can talk to.
PDI.Engineering is me – Kai Chmieleffski, electrical engineer from Ahrensburg. I am not an institution, not an agency, not an anonymous service package. When you hire me, you work directly with me, from the first email to the handover of the completed project.
Good communication is just as important to me as good technology. I gladly explain to you what I am doing and why. I address problems early on, not just when they escalate.
My strength lies in holistic development: I can accompany a project from the idea to the series device: schematics, PCB layout, prototyping, documentation, certification, and much more. For tasks outside my core area, I have built a network of competent partners over the years, which I can fall back on when needed.
I bring experience from measurement technology, railway technology, and years of independent project work, among others. Working with standards such as EN 50155, EN 45545, EN 61000, and others is known to me and, depending on project requirements, part of daily life, not checklists at the end of the project.
