Software development
Software follows your real workflow instead of forcing the organisation into an unsuitable standard process.

- Android and iOS apps
Individual. Practical. Reliable.
IT that works – from concept to operation.
IT-Service Castel delivers practical solutions that simply work in day-to-day use: in-house software, display systems, networks, security and time tracking, with an optional service agreement. Content creation, design and CAD are also available. Tailored does not automatically mean expensive: clear priorities and a well-defined scope provide exactly what is needed without overengineering. Based in Berlin and Brandenburg, available throughout Germany.

German LoFi Beats
German LoFi Beats is my music project for focus, learning and relaxed sessions. The tracks are made with great attention to detail rather than simply produced off the shelf: music from the heart for moments when you need a clear head.
If you enjoy the vibe, have a listen, save a playlist and consider subscribing — it helps enormously.
Gaming community
AOE2GERMANY
Whether you are a fan, veteran or complete newcomer: if you enjoy Age of Empires II, AOE2GERMANY is the right place — the largest German-speaking AoE2 community.
It is all about playing: active matchmaking, events, tournaments, training and, above all, people who genuinely want to play. The community has a friendly atmosphere for discussing tactics, improving together or simply enjoying team games.
I founded the community and AoE2 is a true passion project for me. Join us directly on Discord — we look forward to welcoming you.
