NovaSystems

NovaSystems is my self-funded systematic trading and AI systems business. It trades my own capital and has no outside customers or investors. I design, build and operate its systems myself, with AI coding tools working from written specifications.

How NovaSystems works NovaSystems: live data flows into code that computes every number, then to a self-hosted model for routine work and frontier models for hard calls under a daily spend cap, then through an approval gate to a human decision; the system fails closed on bad data.

Research desk A loop that runs every 60 seconds, fetching data, computing, ranking and publishing, graded nightly. Fetch data Every60 seconds Graded nightly

Research desk

An AI research desk that refreshes every minute: code computes every number, the model ranks and explains.
Nova platform Three layers, data platform, model training and controls, with a pause mark for the review that stopped it. CONTROLS MODELTRAINING DATAPLATFORM

Nova platform

A real-time data and machine-learning platform, and the controls that paused it when a review said stop.
Compass A router sends most work to a self-hosted open-weight model and only hard cases to vendor and frontier models. Router Self-hostedopen-weight model

Compass

A clean-sheet rebuild with a self-hosted open-weight model and cost-capped routing to frontier models.
Aria A busy, alert-filled finance app beside Aria's calm single card. Engagement-driven apps Your plan is on track. Aria

Aria

A design study for an AI wealth manager built to serve the client, not to maximize engagement.
