Sean Cook — San Francisco

AI, data,
and design.

I build things at that intersection.
Previously data science leadership at Meta and Nextdoor.

PondTools.com↗

Pond design and estimating software for contractors and homeowners. Trace a pond on a yard photo or satellite image and get its volume, a 3D model, equipment sized to the pond and a priced parts list, plus an AI image and short video of the finished pond in the customer's own yard. For larger ponds it estimates the lake bed from LiDAR.

AIShovels.fyi↗

An autonomous AI-driven portfolio manager that researches AI-infrastructure stocks daily and executes real trades on a live brokerage account.

Color the Colonies↗

The Earth-Moon problem: a graph G = (V, E₁ ∪ E₂) with both layers planar and χ(G) ≥ 10. The bounds 9 ≤ χ ≤ 12 have not moved in decades. A search that rules out whole families, and logs why.

DanteForData.com↗

A free to use Python library to supercharge Data Science workflows.

Bid4Assets-Reader.com↗

A scraper and viewer for California county tax-defaulted property auctions on Bid4Assets — pulls each parcel's location, satellite imagery, and supporting documents into a single sortable, filterable map and table.

Autopilot↗

An agent looper that runs unattended coding cycles against a project and keeps going for days. Watches its own usage window, gates every cycle behind a verify command it runs itself rather than trusting the model's word, and reports progress in plain English through a web UI.
