Systems Engineering from First Principles
A first-principles treatment of software systems engineering — reasoning from fundamentals rather than inherited patterns to arrive at clearer mental models for architecture, reliability, and design tradeoffs.
A clinical intake agent that guides users through a symptom questionnaire and surfaces supplement recommendations backed by PubMed citations. Built on a supplement knowledge graph and iDISK, with a privacy-preserving session model — no conversation data is stored.
Infrastructure-as-code patterns and examples from real-world AWS deployments.
Two privacy-first skills for the OpenClaw agent platform. Both run entirely locally, require no npm dependencies, and are built on Node.js built-in modules — no build step, no supply chain risk.
Fraud Filter
A community trust network for AI agent payment endpoints. Downloads nightly satisfaction scores, verifies endpoints before transactions, and submits anonymous outcome reports. Endpoint URLs are SHA-256 hashed; amounts are bucketed into ranges — no transaction details leave the machine.
Spend Ledger
A tamper-evident local ledger that tracks payments made through OpenClaw wallet tools. Detects payments via hook integration, records them in a hash-chained JSONL log, and surfaces spending history through a localhost-only dashboard. Includes loop detection and chain integrity verification.
An EHR and patient portal for complementary medicine practitioners. Features customizable SOAP notes, treatment and billing code libraries, superbill generation, and patient-facing iOS/Android apps — built for acupuncturists and CAM providers underserved by Western-medicine EHR systems.
