Services - Software Engineering

Engineering built around data streams

We design systems that process data in real time, scale predictably, and stay understandable for the team that maintains them.

We combine streaming-data specialization with disciplined engineering practice. Every project starts with event-driven architecture and ends with observability, automation, and readiness for production operations.

Real-time data replication (CDC)

A Debezium and Kafka Connect replication platform captures changes from production databases and propagates them to target systems with minimal delay. The event-driven architecture provides no event loss, observability, and fault tolerance.

Data-stream transformation with ksqlDB

A ksqlDB stream-processing layer enriches, filters, and aggregates events in flight. Streams are joined in real time to feed billing systems and network anomaly detection.
