I build infrastructure for agentic workflows — accounting components for React, and guardrails for coding agents.

Ledger UI — a React component library of animated, Excel-like accounting primitives: journal entries expanding to their debit and credit legs, split and merge, reconciliation matching, P&L and balance-sheet views, and entry forms with spreadsheet input semantics. Built to play nice with popular frameworks such as shadcn/ui, Tailwind, Motion.

Fairway — hooks that keep parallel coding-agent sessions off each other's work. Run several agent windows against one checkout and the failure is never a merge conflict; it's one agent staging over work another still holds uncommitted. A single Go binary hooks the harness itself and warns before the wide git operation, not after. ~5ms on the ordinary path, measured.

Deterministic accounting engine — double-entry over crypto + fiat, operated through an AI harness (Claude Code + domain skills) so every number carries its receipts. FIFO cost basis, multi-chain event parsing, per-wallet audit trails. Private; email for a walkthrough.

Regulated systems — an approval engine for a regulated-sector client, with legally binding deadlines. Scoped directly with the non-engineers who own the process.

Solana trading infrastructure — P&L analytics and trade-ledger reconstruction for delta-neutral day-trading and DLMM market-making, across thousands of transactions.

Local ML pipelines — multi-modal (voice / vision / OCR) over 100GB+ on local models, parsing statements, screenshots and recordings into structured, sourced data.

• fairway — the problem, the ruleset, and how the hooks are derived from your own session history.
• solana-app — a Solana program (Rust / Anchor) plus a Node backend: an on-chain event listener over a Helius RPC WebSocket, and a transaction parser over the Helius API.

Most current work is private — email jacob@slvr.mn for a code walkthrough.
