About
I’m Christian Hählen – your point of contact for IT and web. 15+ years of IT projects, systems engineering and support – that experience goes into every Fachbyte project.
A clear process – so you know what to expect.
We talk through your needs and goals – free and without obligation.
I analyse your situation and put together a fitting, easy-to-follow solution.
I put your solution in place – on schedule, documented and tested, so it holds up in everyday use.
I’m still here after the project is done – with support and further development.
From a single workstation to a company team: hospitality, retail, trades, medical practices, office and services.
IT support, Microsoft 365, networks and workflows – one point of contact for everything.
Website, email and devices: all set up so you can focus on the business.
PC problems, a new computer, Wi-Fi at home – explained patiently and solved cleanly.

Book a free initial consultationThe essentials up front about working together.
Most matters I sort out with you directly on screen — by remote support, video call or phone. For on-site work I have local partners, in Switzerland the firm ctrl-alt.ch. You always have the same point of contact.
Both. From a single workstation through the self-employed to a company team: you get the same care, no matter how big your request is.
Transparent and with no hidden costs. Depending on the task I charge by time or offer a fixed price. What makes sense for you we sort out in the free initial consultation – nothing is charged before that.
You usually get a reply the same day, and within 24 hours at the latest on a working day. For urgent faults I deal with them as fast as possible.
Yes. I first get an overview of your current setup and then either take it over as it is – optimising step by step – or rebuild it cleanly if that’s the better route.
Yes. Access runs over an encrypted connection, happens only with your approval and is time-limited. No permanent back door remains on your system.
You decide how we start.
A free initial consultation by phone or video call. No obligation, around 30 minutes.
