Web & Software Development

Websites, web applications and custom software that fit your process and stay maintainable long term.

When a template cannot cover your requirements, we build the website or application you need. That might be a company website, a customer portal or an internal tool connected to your ERP or CRM. We also implement designs you already have.

Technology is a means to an end for us. What matters is maintainability, performance and a codebase your team or a partner can extend later without guesswork. We document architecture and handoff so you are not locked in.

Who this is for

  • Companies with requirements beyond page builders and standard CMS setups
  • Businesses that want to connect their website with line-of-business systems
  • Teams that take performance, SEO and accessibility seriously

Typical web and software projects

01

Marketing site with CMS integration

A multilingual company website with content your team can edit. Clear service pages and structured data help visitors and search engines understand what you offer.

02

Customer portal

Protected area for order status, documents and support requests. Connected to your existing data source without replacing the core system.

03

Internal planning tool

Web interface for processes that used to live in spreadsheets: permissions, history, export and ERP integration. Logic stays understandable for your operations team.

Existing software, Excel and your website

Do you take over software built by other developers?

Yes. We take over existing applications and continue their development, including when the previous provider is no longer available. We first review the source code and documentation. We establish which access credentials are available and how the application can be tested and operated safely.

You receive an assessment of its condition and the next steps. Working parts can stay. Together we agree which issues to address first and which additions are worthwhile. Taking over an application does not require rebuilding it from scratch.

How do you replace an Excel spreadsheet with an application?

We work through the spreadsheet with the people who use it every day. We review formulas and macros as well as rules that currently exist only in someone’s head. We turn this into an application that several people can use with appropriate access permissions.

Existing data is mapped, cleaned and imported in a trial run. We compare calculations against the spreadsheet using familiar examples. The workflow changes only after your review; if needed, both solutions run alongside each other for an agreed transition period.

Do you also build websites with WordPress?

Yes. We build and extend WordPress websites, including custom features and connections to other systems. Whether WordPress or another platform is the right fit depends on what your website needs to do and how your team manages its content.

We can also develop an existing WordPress site further. We first review its theme and plugins, then discuss with you what can be retained.

Does this match what you need?

Tell us about your project. We will discuss a suitable approach and what it requires. Based in Siegen, Germany, we work with businesses across the country.
