Things I build and run.

A data product that connects source-labeled prices, completed-sale evidence, and PSA population data for each exact card, printing, and grade, alongside portfolios, watchlists, market news, and collector discussion.

• 27,000+ catalog products with raw, PSA 9, and PSA 10 price states
• Provenance on every observation; unvalidated valuation models stay gated
• Python web app, ingestion workers, and Terraform-managed EC2 on AWS

A trading system where no strategy trades until it passes a standard evidence bar. A single Strategy Lab replays every strategy, market, and direction under the same costs and fill rules, then applies statistical verdict gates before anything reaches the broker.

• Forex engine live on four major pairs behind hard risk gates and a halt switch
• Crypto research with pre-registered hypotheses and paper shadow trading
• Python services on EC2 with systemd, nginx, and operator dashboards
