All my e-mail addresses also have S/MIME certificates
Shout-out to Actalis — once unlimited free, now freemium (one free cert, ~€6/year to renew) since the 2023 CA/Browser Forum rules ended most free S/MIME, but still about the best option going.
Disclaimer: the private keys are generated by the CA. They claim to delete them after delivery, but I think it is important that you know!
If you need my public key, just send me a blank mail with the subject “Request PublicKey” and I will reply with my key; afterwards we can communicate privately.

Operating systems
I’m pretty experienced with all common operating systems. Experience (from most to least):
Linux (Debian/Arch)
macOS
Windows
FreeBSD
Computer-aided design (CAD)
3D CAD
My daily driver at work is PTC Creo Parametric, where I design apparatus and mechanical parts for medical devices. Privately I reach for Fusion 360 or FreeCAD to create complex apparatus and designs that fit the requested need.
FDM and SLA 3D-printing
Since my first contact with 3D printers in the Laboratory for Semiconductor Devices and Bus Systems of the FH Münster in 2017, I added these devices immediately to my now weekly tool set. I print holders, boxes and even complex apparatuses for my work.
PCB design
Since my time at the Semiconductor lab, I designed and built several small to medium-sized PCBs. These include a measurement board for high current flow from and to batteries, a header PCB for a Raspberry Pi to control two stepper motors and up to 16 servos, and an interface PCB for use with mWorks.
Medical imaging
Working on surgical navigation at cortEXplore, I handle medical image data on a daily basis: importing and registering CT/MRI volumes (DICOM), segmenting and visualizing them with 3D Slicer and VTK-based rendering pipelines, and integrating the results into our C++/Qt navigation software.
