Data & Ethics
Credibility is the product.
Every number in this portfolio traces to an authoritative public source, every license and attribution requirement is honored, and every limitation stays visible. This page documents the practices and cites the data providers behind each product.
Integrity in practice
These aren't aspirations pinned to a wall — they're implemented behaviors. Compet 2026 suppresses any score that falls below its confidence threshold rather than publish bad data when a vendor feed fails. The Global Exchange Planner reports its own negative finding — a naïve baseline beat every forecasting model, so it recommends a risk-managed split instead of fabricating a timing edge. EconOS marks stale series instead of hiding them.
The discipline comes from the day job. Nine years of federal compliance — 2 CFR Part 200, subrecipient monitoring, procurement review — is work where a wrong number has real consequences. Software built by someone who signs off on drawdowns treats data integrity as a professional obligation, not a feature.
Working principles
- Only credible public data: federal statistical agencies, city open-data programs, and documented research datasets.
- Licenses honored: non-commercial and attribution terms are flagged in each repository and respected in each product.
- Computed vs. proposed: calculated outputs stay separate from planned enhancements. No fabricated metrics or impact.
- Honest limits: data-sparse geographies, modeled estimates, and baseline comparisons are surfaced, not smoothed over.
- Reproducible where repo-backed: portfolio pipelines rebuild with one command and validate output against schema gates.
- No personal data: products use aggregate public statistics; nothing identifies an individual.

Citation practice: each product references the provider's canonical name, the specific dataset or series identifier, and the retrieval date in its repository documentation and on-page source notes. Government works are public domain under 17 U.S.C. § 105 unless otherwise marked; non-federal providers (MTA, NYC Open Data, FRED) are used under their published terms with attribution. Data are presented for education and analysis — not investment, legal, medical, or policy advice.
