Achievements: - project 1: "24 hour control over natural gas consumption for Ukrainian railways".Description: the system automates the process of obtaining volumesspent gas from metering devices. The system gives recommendations for troubleshooting metering devices. The system generates various reports on gas consumption for various enterprises.- project 2: "24-hour monitoring of failures of signaling devices (signaling, centralization, blocking) at all signaling and communication enterprises of Ukrainian railways".Description: Dispatchers enter operational information about damage to devices at various stages and stations. The system gives recommendations for troubleshooting. Periodically, laboratory cars pass by railways, which also promptly enter information about the identified damage. The management of the railways analyzes the identified malfunctions and makes decisions to eliminate them. The system generates various reports on detected faults.

Support for highly available and fault-tolerant systems so that they can operate stably under changing loads. Create scripts and use tools to automate routine tasks such as application deployment, testing, and monitoring.
