David Zimmermann

Office Administration IT support Developer & game designer C++ / Lua

I am a reliable and thorough person who likes order in paperwork, processes and communication. I have experience in administration, front desk operations and working in an environment where sensitive matters are handled and following the rules is essential. When I take something on, I see it through and make sure the results stay traceable and still make sense a month later.

In practice that means I can keep several tasks running at once, work systematically and stay on top of things even at peak times. I also have a natural support mindset. I do not go for the quick patch, I look for the cause and fix it so the problem does not come back.

I used to work on the Bradavice Online RP server, where I gained experience developing game systems on WoW 3.3.5a. I learned how important it is to finish every detail and to write things so they still hold together six months later.

Right now I am working on my own project, Realms of Solmira. I build the whole world from scratch, its stories, the laws of its universe and custom RPG mechanics grounded in realism. The technical side runs on C++, Lua and MySQL on AzerothCore. There are two of us on the project and I am responsible for the entire technical part.

My own hobby project running on AzerothCore, an open-source server for World of Warcraft 3.3.5a. I build the whole world from scratch, its stories, the laws of its universe and its internal logic. Alongside that I develop custom RPG/DnD mechanics with an emphasis on realism, deliberately different from the usual game clichés. Details are not optional, either everything fits together or it does not work. There are two of us on the project and I handle the entire technical side myself. The public website and the admin panel are described in the Websites section.

Custom game mechanics in C++ and Lua

I learn mainly by building things and then running them. Certifications take a back seat to practice for now, but I am happy to add them if a role calls for it.

Interests

Development and systems thinking

I enjoy building systems that are consistent and maintainable. I like it when things hold together technically as well as in everyday use.

Technology and news

I follow IT news in a practical way. What interests me is what has a real impact on work, security and everyday workflow.

Stock market

I am interested in investing and a long-term approach. I enjoy working with information and the connections between things.

Cryptocurrencies

Cryptocurrencies interest me mainly as a technology. I look at the principles, the uses and the real impact, not at short-term hype.

Automation and efficiency

When I do something often, I want to simplify it. I like clear processes, traceability and solutions that are still readable later on.

Basketball

Sport is a good reset for me. It helps me keep my energy and discipline and keeps my routine balanced away from the computer.
