Recipes for systems I build. Each one is a step-by-step walkthrough — schema, infrastructure, code, and wiring — so someone else can rebuild it without cloning a repo. Teaching the pattern, not handing off the source.
Dev Secrets with the Proton Pass CLI
Rebuilt my workstation on Debian and lost the macOS Keychain. The Proton Pass CLI injects secrets from an already-synced vault into your dev process. No .env on disk, and agent tokens are scoped and short-lived.
Agent Kanban for Claude Code
A folder-based kanban board that runs inside Claude Code. Tasks as markdown files, gates at every transition, and parallel multi-agent execution.
Cross-App Auth on Cloudflare with Better Auth
One login across multiple Cloudflare apps. A shared worker handles identity, sessions, and invites. Each app resolves its own user profile by auth_user_id.
Dev Secrets with envchain
Store secrets in the macOS Keychain and inject them directly into your dev process. No .env file, no plain text on disk, nothing to run before npm run dev.
AI-Operated Prospecting on Cloudflare D1
A prospecting pipeline backed by D1 that discovers B2B leads from county parcel data and Google Places, enriches them, and lets an AI agent qualify them.
Proton Mail Inbox Triage with Claude Code
A Claude Code skill that connects to Proton Mail Bridge via IMAP, scans sender frequency, and batch-trashes thousands of emails with a CSV audit trail.
AI-Operated Bookkeeping on Cloudflare
Double-entry ledger on a Worker + D1 + R2, with an AI agent that reads receipts, enters transactions, and queries the books through a locked-down API.
