The engineering backbone

Enterprise systems designed, built, and operated end to end: forecourt automation and fiscal compliant point of sale, hospitality platforms, ecommerce, industrial IoT, applied AI, cyber security, and cloud operations.

Real Time Operations

Event driven data pipelines carry forecourt, fiscal, and industrial telemetry at sub second latency, so decisions are made on live data.

Compliance by Design

Bulgarian NRA fiscal rules, GDPR, PSD2, and NIS2 requirements are engineered into every build, verified before release, not retrofitted at audit time.

Hardware to Cloud, One Team

Dispenser controllers, ATG probes, payment terminals, message brokers, cloud ingestion, and dashboards, delivered and supported by the same engineers.

Operational Intelligence

Applied AI with measurable return: demand forecasting, anomaly detection, predictive maintenance, and receipt level fraud scoring.
