The intention is certainly not self-promotion. Rather, it serves as a space to collect and revisit positive experiences, allowing them to outweigh the negative ones.
This choice stems from a blend of reasons: the elegance of design, harmony with my coding environments, a touch of energy efficiency on modern screens, and, above all, to let the colors in the pictures shine more vividly against the subdued backdrop.
None — this website is built entirely with pure HTML, CSS, and JavaScript.
I'm not reinventing the wheel. This website is a labor of love, a hobby project born from pure curiosity rather than economic motives. By crafting everything myself, I minimize reliance on existing technologies, reducing network traffic and cellular data usage. I build only what is essential, embracing simplicity as the foundation of its design. After all, true elegance emerges from simplicity.
Both no and yes. Every idea and intention behind the text is entirely my own. I only use AI to refine my raw drafts into fluent English, as my native language is German.
My research focuses on Turing-Complete Domain-Specific Languages (TCDSLs) — a class of programming languages that combine the expressiveness of domain-specific languages (DSLs) with the full computational power of Turing-complete systems. Traditional DSLs are highly specialized and optimized for specific application areas but often lack the ability to express complex algorithms. In contrast, TCDSLs overcome this limitation by integrating domain-oriented abstractions with a fully expressive computational core, making them both powerful and intuitive.
Theoretical Foundations: Analyzing the structure and properties of TCDSLs.
Meta-Compiler Framework: Automating language transformation via rewriting systems.
Prototype Development: Implementing a proof-of-concept for practical validation.
Experimental Evaluation: Testing TCDSLs in real-world applications.
TCDSLs offer a versatile and efficient way to bridge the gap between domain-specific precision and general-purpose programmability. They enable experts in various fields to express complex ideas in an intuitive language while maintaining the flexibility of a full programming environment. This research paves the way for smarter, more adaptable software solutions in specialized domains, making programming both more accessible and powerful.

Art has been woven into my life for as long as I can remember. As a child, I found joy in drawing, shaping my imagination on paper, and channeling creativity into Lego structures. These small acts of creation were more than play; they were the first echoes of a lifelong fascination with form, color, and expression.
As I grew, my artistic lens turned outward. I captured the world through photography, landscapes drenched in golden light, the quiet poetry of nature, and the pulse of cities across the globe, especially in Europe. Each journey became a search for beauty, not only in grand vistas but in the hidden details of a place. Museums became sanctuaries where I stood in awe of artistic legacies, with a particular fascination for ancient art, those enduring testaments of human creativity across centuries.
In recent years, my creative journey has taken new forms. I have designed logos, shaped digital spaces through websites, and brought architectural visions to life in 3D. For me, creativity is more than an act; it is a counterbalance, a necessary contrast to the structured world of theoretical science. And yet, I do not see them as opposites. I believe that only through the symbiosis of art and science can truly remarkable things emerge. One inspires the other, and together they create something far greater than the sum of their parts.
The data is collected every five minutes using a Raspberry Pi and published here. Please note that temperature readings were too high until the end of May 2018. To improve accuracy, I installed a separate sensor on the north side after that.
