Enterprise Projects

Delivering enterprise solutions

Our core business is building advanced technology projects for enterprise partners. From embedded systems controlling industrial hardware, through financial solutions, to custom mobile applications — we design and deploy software that runs in the most demanding production environments.

Cash & Payment Devices

Software controlling financial self-service devices — ATMs, deposit machines, and cash recyclers. CEN/XFS standard implementation for peripheral communication, integration with cryptographic modules. On the financial systems side, we have the knowledge and capability to develop cryptographic operation modules running on HSM devices.

Self-Service Machines

We build complete solutions for self-service devices used daily by hundreds of thousands of people across Europe. We specialize in the low-level layer — controlling locks, sensors, and communication modules. We integrate the devices with photovoltaic installations and payment terminals. We also develop the cross-platform kiosk application — this is what the customer interacts with at the device.

IoT with Power Management

Embedded Linux for autonomous off-grid devices. Intelligent power management — adaptive sleep states, dedicated Cortex-M33 coprocessor firmware, LTE connectivity with failover, industrial integration (Modbus, I2C, SPI, GPIO). Months of operation on battery or photovoltaic panel.

Custom Mobile Applications

Dedicated mobile solutions supporting the work of technicians, installers, and field service teams. The offline-first architecture guarantees continuity of work and reliable data synchronization, while native integration with the client's ERP and EAM systems and support for scanners, printers, and Bluetooth devices provide full support for operational processes.

Logistics Automation

Controllers for parcel sortation and flow systems in logistics centers. Middleware between PLC controllers and client systems — barcode reading, weight validation, real-time parcel routing, flow visualization and management. Support for standard hardware communication protocols, OAuth-based integration, audit and flow monitoring. We replace legacy systems with modern, fast and reliable solutions.
