Ledger AI — apps like Koinly handle the easy 90%; Ledger AI handles the hard 10% — decoding on-chain transactions into statements for traders, accountants and tax purposes. Hundreds of thousands of on-chain multi-chain events parsed, tens of thousands of fiat transactions reconciled for clients to date. Building this I learned how to reconcile mutable and immutable data sources and I intend to leverage that to add features for monitoring agent spending. https://ledgerai.fly.dev Backend: React Router v7 + TypeScript server with PostgreSQL and Prisma, ~60 models shaped to the GnuCash schema. Inngest orchestrates a multi-step pipeline that ingests Xero (OAuth) and Solana on-chain events (via Anchor and the Meteora DLMM SDK), composes journals, and surfaces P&L and position-lifecycle reports. Current use case is P&L reconstruction of Meteora LP positions on Solana. Frontend: React components that feel familiar if you’re used to MS Excel — high information density with spreadsheet input semantics. Server-side rendered (React Router v7), URL-driven search and filter, forms via Conform + Zod, tables via TanStack Table with keyboard navigation, optimistic UI with useFetcher, and animated transitions via Framer Motion over Radix UI primitives. Components take double-entry-shaped props and animate only the transitions the ledger permits — a split visibly conserves its parent total; the component layer composes over a headless engine rather than wrapping a data grid. Extracted as the Ledger UI component library at https://ledgerui.fly.dev. Agent Harness — Python pipeline for ingesting unstructured data from voice, vision and OCR using local models on MLX (Apple Silicon). Model choice per task via evals (vision-language models benchmarked for OCR on legible vs degraded documents). Structured output feeds downstream pipelines like Ledger AI. Fairway — agentic workflows: guardrails and devtools for collaborating agents. Claude Code’s docs tell you what to do when you ask; Fairway tells you what to do when you don’t know what to ask, and gives you hooks to encourage patterns and discourage antipatterns. Nine small tools sharing one Go binary, one WAL-mode SQLite store and one MCP server, so anything one tool writes another can read — each extending a command Claude Code already ships: /insights, /usage, claude agents and the tool hooks. Includes a concurrency guard that intercepts wide git operations (reset --hard, force push, checkout .) before one autonomous coding agent clobbers another’s uncommitted work — multi-agent-safe by design, no shared state between sessions, pre-run interception at the hook layer. Pick the ones you want: most are read-only pull commands that need nothing installed, and two wire into your setup with explicit install and uninstall verbs. The binary alone creates no files, opens no ports, writes no config. MIT-licensed. Contact for code access. https://github.com/bespy/fairway Verify My Order — contact-lens prescription verification for a US retailer. A companion Shopify app: orders don’t ship until a prescription is verified — a state machine that negotiates between doctors, patients and the retailer over multi-channel communications. Regulated-sector approval engine with legally binding response deadlines, scoped directly with the non-engineers who own the process. https://verifymyorder.com · https://dimplecolor.com
