What we build

From the first line of code to production infrastructure — everything from one source.

Websites & Web Apps

Astro · Next.js

We build web applications that not only look good but perform. From marketing websites through content management systems to complex, database-driven SaaS platforms — we cover the full spectrum. Our focus is on fast load times, WCAG accessibility and an architecture that grows with your business.

  • Server-Side Rendering & Static Generation
  • CMS integration (Storyblok, Contentful, Strapi)
  • SEO optimisation & Core Web Vitals
  • Accessibility to WCAG 2.1 AA

Mobile Apps

React Native · Swift

Mobile apps that deliver real value. We develop native apps with Swift (iOS) and cross-platform solutions with React Native or Flutter — whichever makes most sense for your use case. We focus on platform-native interaction patterns, smooth animations and UX that keeps users coming back.

  • iOS & Android from a single codebase (React Native / Flutter)
  • Native Swift development for demanding iOS apps
  • App Store & Google Play submission
  • Push notifications & offline capability

Desktop Applications

Tauri · Electron

Desktop software that accelerates workflows. Whether a lean utility tool or complex business application — with Tauri, Electron or .NET we build software that runs on Windows, macOS and Linux. We prioritise native-feeling interaction, low system requirements and reliable update mechanisms.

  • Cross-platform: Windows, macOS, Linux
  • Rust-based Tauri for minimal system requirements
  • Automatic updates via Sparkle / electron-updater
  • Native system integration (Tray, Notifications, Filesystem)

IT Infrastructure

Docker · Kubernetes

Good software deserves good infrastructure. We design and operate cloud architectures that scale with your requirements — without vendor lock-in and with an eye on running costs. From the first CI/CD pipeline to a production-ready Kubernetes cluster, we guide you through every phase.

  • CI/CD pipelines (GitHub Actions, GitLab CI)
  • Container orchestration with Kubernetes
  • Infrastructure as Code (Terraform, Pulumi)
  • Cloud architectures (AWS, GCP, Azure, Hetzner)

AI Integration

AI Integration

AI is not an end in itself. We analyse whether and how AI actually helps your product or process — and then implement it cleanly and maintainably. From RAG-based document assistants to automated data extraction and AI-powered features in existing applications. We choose the appropriate model (local or cloud-based), build the necessary infrastructure, and explain what we do and why.

OpenAI LLMs Embeddings RAG
  • RAG (Retrieval-Augmented Generation) for knowledge bases
  • Automated data extraction & classification
  • AI-powered search functionality
  • Fine-tuning & prompt engineering
  • Local models (Ollama, llama.cpp) for privacy-critical applications
