Back to original languageAbout Nicolas
I have been working in the field of technology since my youth. Since the beginning of my computer science studies and after graduation, mainly in the software sector. During my training as an Electrical Engineering Assistant, I also had a strong hardware focus, which I have also been able to use in some projects. In recent years, I have mainly worked in the microservices area with Java/TypeScript/Kubernetes/OpenShift.
However, I am constantly trying out new technologies and have also worked a lot in the graphics/vision area in the past and am developing various personal projects here (e.g., VR/XR applications and applications with 3D cameras or 3D reconstructions). These applications are often combined with C++/Python and/or Android (Java).
