Cybersecurity

QuantGPT

Reduced cryptographic threat assessment build times from weeks to milliseconds for a Tier-1 Canadian bank by developing an Agentic AI framework leveraging on LLMs and Knowledge Graphs.

Factor Strategies

Systematic Trading Research

Inside joke, documented

Factors, Strong Opinions, Weakly Held

The inside joke version: the concept of a factor was introduced by Peter Brandt, then rediscovered whenever a trader gave a signal a clean name and actually tested it.

The serious version: a factor here means a repeatable market signal with a database contract, a validation window, and a public artifact that can be audited without exposing the private feed.

Data Private parquet database

Signals are computed locally, then compressed into public JSON/CSV outputs.

Validation Selectable backtests

Performance views are derived from monthly validation returns, not live browser-side market calls.

Strategy Momentum

The active model ranks equities monthly and publishes only selected holdings, diagnostics, and derived backtest data.

Momentum

Sequence Portfolio

Monthly equity ranking model using a private local market database, a frozen sequence-v3 checkpoint, and public static outputs.
