Real-time Regulatory Compliance
The Core Challenge & Constraints
Apex's legacy mainframe batch reconciliation took 6 hours each night, creating massive settlement credit risks and regulatory reporting friction under revised Basel IV standards.
The InventIQ Engineering Solution
We engineered a distributed event-sourced architecture using Apache Kafka and memory-mapped Rust workers, orchestrated within private Kubernetes clusters across Frankfurt, New York, and Tokyo.
Key Technical Architectural Decisions
Zero-allocation memory serialization using FlatBuffers over TCP/gRPC
Active-active Byzantine fault-tolerant state machine replication
Automated real-time reconciliation with ledger cryptographic verification
Executive real-time liquidity dashboard built on Next.js & WebSockets
“InventIQ delivered what two prior tier-1 consulting firms said was mathematically impossible within our compliance envelope. Our settlement engine is now the benchmark of Wall Street.”
