Software Development
Web development, app development and custom software — tailor-made, performant and built around your business. We build digital products that keep working: cleanly built, easy to maintain and ready to grow.
01 · Web Development
Websites: fast and maintainable.
From landing pages to complex web applications — we build fast, maintainable websites to WCAG guidelines and with modern technologies. We think about performance, search visibility and upkeep from the very start.
Marketing
Websites & landing pages
Fast-loading company sites and campaign landing pages, built cleanly for search engines and strong on every device.
Applications
Web applications & portals
Customer portals, booking systems, dashboards and SaaS platforms — with user management, roles and interfaces to your systems.
E-commerce
Online shops
Shops with WooCommerce, Shopify or custom-built: fast pages, clean checkout processes and connections to inventory and shipping.
Content
CMS & editing
Maintain content yourself without technical knowledge: WordPress or a headless CMS, set up to fit, with clear roles and simple workflows.
02 · App Development
Apps for mobile and desktop.
Native and cross-platform apps for iOS and Android as well as desktop apps for macOS and Windows — thought through in UX and design, strong in performance.

iPhone & iPad
Native apps in Swift and SwiftUI: fluid, secure and close to the platform — including widgets, push notifications and Apple services.
Android
Apps for smartphones and tablets with clean architecture, modern design and publication in the Google Play Store.
Cross-platform
One codebase
With Flutter or Ionic, one app for iOS and Android is built from a shared codebase — when reach and budget matter.
Desktop
macOS & Windows
Desktop apps with Electron and local data storage — connected to your backend, with updates and secure storage of credentials.
03 · Custom Development
Software that fits exactly.
When off-the-shelf solutions are not enough: we develop custom software, interfaces and tools exactly to your requirements — from prototype to production use.
Backend
APIs & data storage
Clean data models, REST interfaces and authentication — the stable foundation for web, app and automation.
Integration
Middleware & interfaces
Shop, ERP, CRM, payment providers and shipping talk to each other: we connect systems that used to work apart.
Internal
Internal tools
Admin interfaces, dashboards and workflows that replace spreadsheets and manual work — fitted to your processes.
Modernization
Replacing legacy systems
Grown software is modernized or replaced step by step — without stopping day-to-day operations.
04 · Quality
Built for performance and longevity.
Good software is not recognized by its looks alone but by speed, accessibility, security and maintainability. For us these belong to development — not to rework.
Performance
Fast on every device
Optimized load times and good Core Web Vitals benefit your visitors — and are one of the factors search engines take into account.
Accessibility
Usable by everyone
Semantic HTML, good contrast and keyboard operation according to WCAG — important for all users and with a view to the European Accessibility Act.
Security
Secure from the start
Secure authentication, validated input, regular updates and backups protect data and operations.
Maintainability
Clean, documented code
Clear structure, tests and documentation make further development and handover easy — today and years from now.
05 · Process
In four steps to the finished product.
We work in short stages with regular interim results. That way you keep an overview and can steer at any time.
Step 1
Concept & planning
Goals, target group and scope are clarified. The result is a plan with priorities, effort and timeline.
Step 2
Design & prototype
Flows and interfaces are created as a clickable prototype — testable before the first line of code is written.
Step 3
Development
Implementation happens in stages with regular test versions, automated tests and short check-ins.
Step 4
Launch & support
We take the project live, monitor the start and support you with maintenance, updates and further development.
06 · Technologies
Modern tools, proven in use.
We choose technology to fit the task: established standards instead of short-lived trends. Here is an excerpt from our stack — the glossary lists all technologies with context.
