Example problem: Sort incoming customer requests, summarize long documents, pull details from contracts or invoices.
Agents and bots
Build agents and bots that do one specific job using tools they have permission to use.
Example problem: A bot that answers common questions, or an agent that looks up internal data and drafts a reply.
AI tools and products
Design and build internal tools or AI products, from the idea to a working version.
Example problem: An internal tool for one team, or an AI product for your own customers.

EXPERIMENTS
Experiments and research
Experiments of my own, including the results that did not turn out as hoped.
Research Testing macro indicators for gold
The MacroLens project tests macro indicators with pre-registration, placebo runs and a locked holdout. As of 08/11/2026: 160 tests, 0 passed; no indicator has been shown to have an edge. The value is the honest validation method, not a trading signal.
Engineering A tested building-block library for EAs
A set of technically tested code blocks used to assemble EAs, with boundary-value checks: 209 checks, 0 failures (from internal test logs, 08/11/2026).
