Software development

Need something specific and want software of your own? I build custom software around your needs, from an internal tool or standalone app to a CRM you can run on your own servers.

When standard software does not fit

Custom software makes sense when existing tools cannot support important workflows or come with so many features that they become unnecessarily complicated for your needs. You get an application whose functions and interface fit the way you work.

This could be an internal tool, an application for preparing and processing data, your own smartphone app or software for a very specific use case. A solution you operate yourself can reduce your dependence on subscription software services (SaaS) and give you more control over data, features and future development.

From workflow to application

We start by describing the key tasks: who uses the application, which information they need and what result they expect. An initial prototype makes the interface and scope tangible.

I then build the application and test it with you against the agreed tasks. Existing data can be transferred. If other programs need to be connected, we clarify which information they should exchange and which interfaces are available.

Plan for data and operation

We agree where the application will run, who can access it and how its data will be backed up. If your own IT team will operate it, I coordinate the technical foundation and setup with them.

You receive the source code and documentation covering setup, operation and further development. This enables your IT team to maintain and extend the application after handover. If you would like further support from me, we agree its scope. Hosting and external service costs are discussed in advance.

Common questions

Can you extend an existing application?

That depends on its technology, source code and available interfaces. I first assess the options and whether an extension makes sense. Access to external systems is agreed with you beforehand.

Which devices can the application run on?

Applications can be developed for desktop (macOS, Windows, Linux), smartphones (iOS and Android) or the browser. The right approach depends on who will use it, their devices and the functions they need.

Can the application work without an internet connection?

Many functions can run locally on the device. We agree which data and tasks need to be available offline. Synchronisation and connected online services still require a connection.

How can the application be changed or extended later?

The application is structured to support future development. You receive the source code and the documentation your own IT team or other developers need to continue working on it. If you wish, I can handle later changes and new features.

How much does custom software development cost?

That depends on what the application needs to do and the scope of the project. A small internal tool involves a different amount of work from an app with several user roles and connected systems. Send me an enquiry, even if your idea is not fully defined yet. We will discuss what you need and agree the scope together. I can then prepare a free quote.

Got an idea? Let's make it real.

Tell me briefly what you have in mind, even if it's still fuzzy. I'll get back to you within 48 hours.
