Websites & online shops
From a small business website to a custom WooCommerce shop.
Custom development
What can I build for you?
Apps & web apps
Applications for Android, iPhone, and the browser.
Automation
Automate repetitive work with Excel, data, emails, APIs, and software.
AI & custom software
AI assistants, Telegram bots, and software tailored to your needs.
The collection
Different projects, each with a reason to exist
Some began as my own ideas, others were created for clients — every one of them is used by real people.
From ideas to products
Plush&Loops makes learning finger knitting easier. Myst Universe preserves a world and its community. Dagnarus is where my free programs, experiments, and game projects live.
Platforms built with people
Kursavo, allaresurs.de, and client websites grew from real needs: teaching, selling, booking, publishing, and keeping in touch with an audience.
Digital restoration
I also restore and adapt old games so they can run and look right on modern systems. Some remain private because their enhanced materials belong to other authors.
