R&D is responsible for the development of devices at Ajax, which consists of four departments: System, Device, Automation and QA. The System Department makes devices smart, turning them into a full-fledged IoT. They created and develop OS Malevich (a modular RTOS for various hardware platforms) and cloud service Ajax Cloud (Java 20 / Kotlin, AWS, Akka, NATS, Kafka, Mongo, MySQL). Applications for iOS (Objective-C, Swift), Android (Java, Kotlin), Windows/macOS (Python / C++, QT, QML) have been developed for system management, maintenance and monitoring by users, installers and engineers of security companies.
