Green, frothy and slightly mocked: matcha is what keeps me running. Coffee had its chance.

The one with the curls and the golden glasses. There is no agency behind Xellux, just one person: every app, every design and every reply comes from me.

No agency story. One person, one plan and quite a few late nights.
During my IT specialist apprenticeship I realize quickly: software is not a job to me, it is a craft. I want to understand how things work, down to the last line.
As a Shopware developer I build online shops that move real money. That is where you learn what software has to withstand: load, security and users with zero patience for bad interfaces.
I found Xellux in Bremen: design, code and AI from one pair of hands, as a subscription instead of project chaos. No overhead, no handovers, one signature style.
The studio grows into Xellux: CRM, appointments, quotes with online signature, e-invoicing and projects on one customer file, all with one login. Everything comes from one pair of hands. Mine.
All from one pair of hands
4 apps, one account. And this is just the start.
You always talk to the person who builds. No tickets, no handovers, no hold music.
Clean code, considered design and AI exactly where it actually helps.
Clear answers, honest numbers and no agency fluff. I tell you how things are.

My trademark since day one. You will spot me in any call at first glance.
I nudge pixels and animations until everything feels right. Even at 2 a.m.
My best code happens after midnight. Sadly my best ideas too, usually right before falling asleep.
Xellux Meet and the Xellux ID started as side projects. Some side quests just become the main quest.
I also exist as a sticker. Real-life Can waves less, the glasses are the same.
Why all this?
Bremen, Germany
I have seen often enough what happens when too many hands work on software: it gets slow, expensive and ends up feeling like nothing.
Xellux is my counter-proposal. Products that play together, one account for everything and one signature style. With one promise: it feels right, or it does not go live.
Message me directly or follow along. It is always the same person answering: me.
