Services in detail

What we actually deliver.

Custom software development from architecture to production. Open-source platforms have their own pages.

01

Web, Mobile, Desktop & POS

One software family for every surface your users sit in front of. Web with React and Next.js, mobile apps via Capacitor from the same codebase, desktop and POS apps with C# and .NET - including native integration with hardware and legacy systems.

  • Scalable web apps with React, Next.js, and TypeScript
  • iOS and Android via Capacitor from the same codebase, no separate mobile team needed
  • Desktop applications with C# / .NET (Avalonia, WPF, MAUI) for Windows, macOS, and Linux
  • POS software with native integration: receipt printers, scanners, card readers, TSE
  • Native capabilities via Capacitor: Push, Geo, Camera, Biometrics
  • API integration in any direction: REST, SOAP, and GraphQL - even in legacy environments
  • App-Store publishing including review process
  • PWA mode as a web-first alternative
02

IoT & Connectivity

Where the physical world meets software. Scanner apps, booking and access systems, trackers, POS, live data, and push - all on one real-time pipeline, including hardware selection and secure data flows.

  • Barcode/QR scanner apps for iOS and Android (Capacitor + native Camera API)
  • Booking and reservation systems with slot management and payment
  • Access systems: ticketing, check-in, door openers, wallet integration
  • POS systems with German KassenSichV-compliant TSE (DSFinV-K, fiskaltrust, etc.)
  • Real-time updates via Socket.io / WebSockets, Web Push, APN, FCM
  • GPS trackers with live map, geofencing
  • IoT integration via MQTT, BLE, NFC, RFID
  • GDPR-compliant data on EU infrastructure
03

Technical Consulting

Before you spend money, get a clear picture. We analyse your situation, evaluate stack options, and flag the risks.

  • Architecture reviews of existing systems
  • Stack selection for new projects
  • Code audits with concrete remediation
  • Effort estimates and roadmaps instead of gut feeling
  • Sparring for internal teams, no long-term lock-in
04

Salesforce & System Integration

Connect Salesforce, ERP, and cloud into one data flow, instead of isolated silos. We build the layer in between, so data is entered once and stays current everywhere - across multiple countries too.

  • Connect Salesforce to your ERP and existing systems (e.g. Navision)
  • Enter data once, current everywhere - no double maintenance
  • One central interface (GraphQL) instead of many fragile point-to-point links
  • Connect existing systems, don't replace them
  • Across multiple countries and tenants too
05

Cloud Operations & DevOps

Cloud that just runs - without your own ops team. EU infrastructure (Hetzner) by default. If your setup requires Azure, we run it cleanly in the EU region - automated and with protected access.

  • Secure operations on EU infrastructure (Hetzner) or Azure in the EU region
  • Automated updates and deployments without downtime
  • Separate environments for testing and production
  • Managed access and protected credentials
  • Auditable and GDPR-compliant

Open-Source Platforms

Off-the-shelf tools, operated by us.

When custom code isn't needed: three open-source platforms we set up, brand in your colours, and operate.
