Nexus Data Fabric
Real-time market sentiment & risk intelligence layer
Nexus is a real-time intelligence fabric that fuses market data, news and analyst commentary into a single risk surface — used by traders and risk officers to react to events seconds, not minutes, after they happen.
The challenge
Risk officers were stitching together five vendor feeds in spreadsheets. By the time a sentiment shift made it into a memo, the trading desk had already taken the hit.
Our approach
We built a streaming Kafka pipeline into a custom retrieval stack backed by ClickHouse and Pinecone, with fine-tuned Gemma 4 clusters scoring sentiment and exposure per instrument. Latency is held under 250ms end-to-end.
The outcome
Nexus now scores 1.4M events per minute, surfaces sentiment shifts 7x faster than the previous tooling, and has become the primary risk console on three trading floors.
What we built
- Fine-tuned Gemma 4 clusters with per-instrument sentiment heads
- Sub-250ms end-to-end streaming pipeline
- Hybrid BM25 + vector retrieval with cross-encoder re-ranking
- Risk-officer console with explainable exposure breakdowns
