Sound familiar?
Three problems I see all the time.
Your website doesn’t show how good your business really is?
Many companies do excellent work but lose customers and applicants to competitors because their website is outdated and slow.
See web design & relaunch →You and your team are drowning in manual data entry between shop, Excel and ERP?
Prices are typed in by hand, stock levels don't match, and agencies quote €50,000 for a PIM system.
Lean PIM & integrations →Nobody understands your IT landscape anymore?
From the old on-site server to Microsoft 365, printers and hardware on site: you need a system that simply works.

How we work together
Four steps. No surprises.
-
Talk & understand
We talk about your plans, your customers and your processes – by phone, video or on site. Afterwards you get a clear, written quote.
-
Concept & look
I sketch structure, content and design. You see early on where it's heading and can step in at any time.
-
Build
I build, test and show you progress on a protected preview. No black box, but regular, honest updates.
-
Launch & support
Once you approve, everything goes live – with a handover and documentation. And afterwards I'm still there for maintenance, updates and new ideas.
About me
Honest, down to earth, reliable.
I'm not an agency machine with project managers and ticket systems. When you call me, you talk to the person who actually builds your website or sets up your IT. I listen, tell you honestly what makes sense and what doesn't – and stay reachable long after the project has gone live.
Sascha Liesener
Digital craftsman from Mülheim an der Ruhr
More about me →
Plain talk, no jargon
You always understand what I'm doing and why. If something doesn't make sense, I'll tell you – even if I could earn money from it.
Thinking along, not just ticking boxes
I ask about your processes and numbers before writing a single line of code. That's how you get what you really need.
Still there after launch
Maintenance, updates, new ideas: you have one dedicated contact who knows your project.
Project or problem?
Tell me about it.
Whether it’s a new project or IT that just needs to work again: a quick call or a few lines are enough. I’ll tell you honestly what I think – and what it takes.
