HORUS

HORUS is a Hazelcast Solution Partner headquartered in Warsaw, Poland, with a team of 80 engineers building mission-critical systems for large enterprises (500+ employees) in telecommunications, banking, insurance, retail, and manufacturing.

We implement Hazelcast where milliseconds matter: distributed caching, in-memory data grids, and real-time stream processing inside high-throughput platforms. Our Java-first engineering team (Spring Boot, Kubernetes) builds Online Charging Systems (OCS) and billing platforms where Hazelcast delivers low-latency state management. We also integrate Hazelcast with Camunda – where we hold Platinum Partner status – and Temporal in end-to-end orchestration architectures. That same architectural approach powers the provisioning platform we built at Play (P4), Poland’s largest mobile operator, serving 15M+ subscribers and executing 30M workflows per month.

Typical engagements include caching layers for core banking and insurance systems, event stream processing, session and state replication in clustered environments, performance tuning of existing Hazelcast deployments, and migration from legacy in-memory solutions. Every project ends with a full competence transfer to the client’s internal IT teams.

We primarily serve clients in Poland and are open to engagements across EMEA and beyond.
