01 Services

Your business, your software.

We develop the right solution together.

Websites

from €1,200
approx. 4 to 12 weeks

The first thing customers see before they ever walk in — as good on a phone as on a desktop.

  • From a one-page calling card to a multilingual company site
  • Update your content yourself, at any time
  • Search engine optimisation included

Apps

from €4,000
approx. 3 to 7 months

For iOS and Android, or as a web app with no store at all. Including existing apps that nobody maintains any more.

  • Reach customers, visitors and prospects
  • Internal apps for your team, field staff and warehouse
  • Publishing to the App Store and Google Play included

Windows

from €3,000
approx. 2 to 5 months

For the machine in the shop, the office or the workshop. Offline operation possible.

  • Interfaces built with WPF or WinUI on current .NET
  • Connections to external interfaces
  • Automation of routine work

CMS & database

from €3,500
approx. 2 to 5 months

One place for customers, orders, products and appointments instead of five spreadsheets. As a website, an app or a Windows program — or all three at once.

  • Exactly the fields and workflows you need
  • Individual access rights for management, office and staff
  • Reports, exports, automatic backups
  • Migration of your existing data

And afterwards: operation.

Your site runs with me, not with a provider you can never reach. Monthly, with three months' notice.

Unused hours expire at the end of the month. Pay a year in advance and one month is free.

02 Clients

Businesses that outgrew the website builder.

Most of them share the same problem: a site nobody can maintain any more — or an idea no off-the-shelf software covers.

03 Approach

Agile project management.

Short cycles with clear goals instead of a rigid specification. The main benefits:

  1. Room for flexibility
  2. Optimisation during development, not after
  3. Planning the next step together

As a certified Scrum Master and Product Owner I have worked this way with teams since 2022. It pays off most on larger projects: the more that is already built, the more a late change of direction costs.

Modular

Grows with your business

Built in modules and extensible: new parts are integrated into the system instead of rebuilding what already works.

Budget

There is a solution for every budget

You name the range. I show you transparently what is feasible and what is better kept for a later stage.

Speed

Urgent projects can move faster

A larger budget buys extra capacity when the deadline is tight; I bring in partners I have worked with for years. Carefree for you: contact, responsibility and warranty stay with me.

Quality

German engineering quality

Cleanly structured code, deadlines that hold, and a solution-focused approach to technical challenges.

04 Qualifications

Learned, examined, certified.

Certificates alone do not make good software. They do show that the fundamentals were examined, not just picked up along the way.

The more complex a data model, the more I enjoy designing it.

05 Why custom

Why not just use WordPress?

Around 40 % of all websites are built with WordPress. What looks cheap at the start often turns into a cost trap.

Off-the-shelf template

  • Only what the theme allows is possible
  • Changes need yet another plugin — or cannot be done at all
  • Subscriptions for theme, plugins and maintenance, rising every year
  • Nobody knows in advance what later changes will cost
  • Ten to thirty third-party extensions as an attack surface
  • A single update can break the site overnight

Built by hand

  • Whatever you want is possible
  • I implement changes directly in the code
  • No recurring licence or subscription costs
  • Extensions get a fixed price up front as well
  • Small attack surface, updates handled by me
  • Only the code you need: fast loading, better search rankings

In my experience WordPress is a mature product. For private sites, hobby projects and blogs it is often exactly right, and agencies work with it too. Still, you can usually spot a WordPress site at a glance: something has slipped, something does not work, or the layout breaks on a phone. What bothered me most was the lack of freedom — a site written from scratch has no such limit.

Self-service

What you can change without me

The editing interface is tailored to your requirements. Together we decide what you want to maintain yourself. And of course I am happy to take care of all of it for you.

Search engines

Found where it matters

Clean HTML, short loading times, meaningful titles and structured data for opening hours and reviews, plus your Google Business Profile. Nobody serious will promise you first place — but measurably you are clearly ahead of a typical website builder page.

06 Portfolio

Example sites.

07 Process

From an idea to software that runs.

01 · First call

30 minutes, free of charge

By phone or on site. I will tell you honestly whether I am the right person.

02 · Quote

Fixed price, in writing

Scope, price and schedule are settled before the first line of code is written.

03 · Development

First results early on

Real working versions instead of progress reports. What comes next we decide together.

04 · Launch and operation

I keep looking after it afterwards

Hosting, updates, backups and small changes at a fixed monthly price.
