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.
Ledger AI — high-volume financial reporting for crypto and fiat. Double-entry over both in one ledger, operated through an AI harness (Claude Code + domain skills) so the model proposes and a deterministic engine computes. FIFO cost basis, multi-chain event parsing, per-wallet audit trails, every figure traceable to the event and rule that produced it.
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.
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.
- What are the types of agentic harness? — four types, told apart by what the model is pointed at.
- Where to deploy an LLM in 2026 — why renting a GPU is getting hard to buy, and who is left needing it.
- What is deterministic accounting software? — derive the ledger from inputs and rules instead of storing rows you edit.

- 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.
