◇ The problem
Where they were stuck.
Helios analysts were drowning in 6 separate dashboards and lost an average of 90 seconds per decision. Latency was killing alpha.
◇ Our approach
How we shipped it.
- 01
Replaced the multi-dashboard sprawl with a single, keyboard-first command surface.
- 02
Built a streaming feature store on top of ClickHouse + Redis with sub-50ms p95.
- 03
Trained a domain-tuned LLM judge to rank news/sentiment events against open positions.
- 04
Wrapped every model decision with a full eval harness and human-in-the-loop overrides.
