Custom Development

Web, Mobile, Desktop & POS

From the browser to the checkout counter: one software family for every surface. Web with React and Next.js, mobile from the same codebase, desktop and POS native with C# and .NET, including integration with hardware and existing systems.

  • Web apps with React, Next.js and TypeScript
  • iOS and Android from the same codebase, no separate mobile team needed
  • Desktop applications with C#/.NET for Windows, macOS and Linux
  • POS software integrated with printers, scanners, card readers and fiscal devices
  • Push, location, camera and biometrics natively integrated
  • Interfaces in any direction: REST, SOAP and GraphQL, legacy systems included
  • App Store publishing including the review process
  • PWA when a store app isn't needed

Custom Development

Salesforce & System Integration

Connect Salesforce, ERP and cloud into one data flow instead of maintaining isolated silos. We build the layer in between: data is entered once and stays current everywhere. We already run an integration like this in live operation.

  • Connect Salesforce to ERP and existing systems (e.g. Navision)
  • One central interface (GraphQL) instead of many fragile point-to-point links
  • Connect existing systems, don't replace them
  • Across tenants and countries, with clean data mapping

Custom Development

Cloud Operations & DevOps

Cloud that just runs, without an in-house ops team. Hosting in Germany or the EU (Hetzner) by default, depending on your needs. If your setup requires Azure, we run it in the EU region with a data processing agreement.

  • Automated updates and deployments without maintenance windows
  • Separate environments for testing and production
  • Access managed, credentials protected, changes traceable
  • Monitoring and backups included, auditable and GDPR-compliant

Custom Development

IoT & Connectivity

Where the physical world meets software. Scanner apps, booking and access systems, trackers and tills: connected live, including hardware selection and secure data flows.

  • Barcode and QR scanner apps for iOS and Android
  • Booking and reservation systems with slot management and payment
  • Access systems: ticketing, check-in, door openers, wallet integration
  • POS systems compliant with German fiscal regulations (TSE)
  • Live updates and push on iOS, Android and the web
  • GPS tracking with live map and geofencing
  • Connecting devices and sensors: NFC, RFID, Bluetooth

Custom Development

AI Solutions

AI pays off where it solves a real problem, not for its own sake. We assess your use cases, integrate language models into existing systems, and keep data and operations in the EU.

  • Identify use cases and check feasibility before any development
  • Answers from your own data (RAG): documents, wiki and tickets, with source citations
  • Integrate language models into existing systems: chat, search, classification, extraction
  • Self-hosted open-source models or EU-hosted APIs instead of US cloud
  • Process automation: document processing, email triage, data reconciliation
  • GDPR and the EU AI Act: risk classification, transparency duties, clean data flows
  • Training for internal teams: prompting, model limits, sensible use cases

Custom Development

Technical Consulting

Before you spend money, get a clear picture. We analyse your situation, evaluate the options, and say openly where the risks are. Even when the answer is no.

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

Open-Source Platforms

Ready-made platforms, run by us.

When custom code isn't needed: we set up Keycloak, OpenDesk and Typo3, brand them in your design, and run them on EU servers.

Let's talk about your project.

30 minutes, free, no strings attached. Afterwards both sides know whether it fits.
