Software.
Hardware.
Systems.
We develop custom technical solutions for companies, public authorities and international clients — from PCB and embedded system to secure cloud infrastructure and the finished application.
Software does not end at the screen.
An application is only as reliable as the system behind it. We therefore treat electronics, operating system, communication, backend, data storage and user interface as one technical unit.
QNTUM21 can develop individual components or take responsibility for the complete system architecture — from the first functional prototype to the documented, operational solution.
From electronics to application.
Each discipline remains clearly defined while sharing one technical architecture. The result is a system that can be operated, maintained and developed in a controlled manner.
Applications for real processes.
Native, cross-platform and web-based applications for businesses, public authorities, technical teams and international users.
Software directly at the hardware.
Firmware, bootloaders, drivers, real-time functions and diagnostics for custom ECUs, black boxes, data loggers and gateways.
Connect devices securely.
Telemetry, remote configuration, device identity, fleet management and controlled software delivery for connected systems.
The technical foundation behind it.
Scalable backends, APIs, process automation, monitoring and private, hybrid or cloud-based infrastructure.
Keep data under control.
Protected data storage, clear access models, encryption, audit trails, recovery strategies and resilient architectures.
Turn signals into system states.
Classical, neural and self-learning signal processing for pattern recognition, sensor fusion, condition assessment and anomaly detection.
Dedicated electronics. Built for the task.
Where standard components fail to meet technical or security requirements, we develop the complete electronic system — from circuit architecture and component selection to PCB layout, prototyping, firmware and customer-specific calibration data.

The architecture follows the system.
Sensors, actuators, buses and external services are connected according to the application — including proprietary and customer-specific interfaces.
The scope also includes analogue and digital I/O, frequency and PWM signals, power outputs and project-specific communication paths.
Protection starts in the architecture.
Security is not added at the end. Device identity, key management, update paths, permissions, auditability and recovery are considered during system design.
Automotive, aviation, public sector and defence environments.
Applicability, qualification and certification are defined per project according to use case, safety class and target market.

Operating systems
Custom engineering, not a product catalogue.
We join where standard solutions no longer fit — as the engineering partner for one component or for the complete system.
Control units, gateways and black boxes
Custom hardware, firmware, communication and diagnostics.
IoT and telemetry platforms
Device management, remote access, monitoring, updates and secure data paths.
Apps and web-based portals
For internal processes, clients, public authorities and international users.
Test and analysis systems
Data acquisition, automated testing, signal processing and reports.
Protected platforms
Backends, databases, identity and operation for elevated protection needs.
Keep existing systems operational
Analysis, redevelopment and controlled migration of legacy platforms.
One system. Clear responsibility.
Requirements
Understand use case, functions, interfaces, protection needs and certification goals.
Architecture
Plan hardware, software, data flows and operation as one system.
Development
Implement, integrate and document all components.
Verification
Test functions, failure modes, interfaces and security controls.
Operation
Support commissioning, monitoring, updates and further development.
The task determines the architecture.
