A reference architecture for real-time pipelines on Databricks. Auto Loader, DLT, expectations, and SLOs that survive production.
Three Uncorrelated Edges: Designing an AI-Native Quant Stack
A quantitative research stack with one edge is a strategy. A stack with three uncorrelated edges is a portfolio. Here is how Sigma Axion is structured, and why uncorrelated edges matter operationally.
The Agent Factory: Planner, Executor, Critic, Referee
Most production agentic systems converge on the same architecture: a planner, an executor, a critic, and a referee. Here is the pattern, why it works, and how we apply it across industries.
Living Systematic Reviews: Evidence That Stays Current
A traditional systematic review is a snapshot, frozen at the search date. A living review is a stream, refreshed as new evidence appears. Here is the architecture that makes living reviews operationally feasible.
Dimensional Modeling on Delta Lake — and When to Choose Data Vault Instead
Star schema, data vault, one-big-table, federation. Each has a different shape and different trade-offs on Delta Lake. A decision framework.
Causal AI for Aviation Operations: from Correlation to Cause
Most aviation analytics tell you what correlates with delay. Causal AI tells you what causes it — with sensitivity analysis. Here is how the AeroFarr causal layer works, and why it matters operationally.
