About
I've traded crypto since 2020, and when tax time came across 20+ wallets, multiple chains, and a collapsed exchange, nothing could handle it. So I built my own: double-entry ledger, FIFO cost basis, per-wallet audit trails. That same instinct runs through everything here — Solana DeFi P&L analytics, on-chain event tooling, Xero financial reporting, and data pipelines that turn high-volume mess into something legible. I'm a hardware and software power user, and I share what I learn about AI and tooling for staying productive solo.
Open to software-engineering roles in AI and crypto — remote, or based in Tel Aviv.

Declarative double-entry accounting for crypto and fiat — the ledger is derived from rules and raw events, regenerated rather than hand-edited, so every balance is reproducible and audit-grade. FIFO cost basis, multi-chain event parsing, per-wallet provenance, multi-entity consolidation, price resolution, and Australian CGT. The fiat side integrates Xero (OAuth + Stripe billing) for customers spanning REITs, private credit, lenders, and vCFOs. Built because no existing tool could handle DeFi positions, collapsed exchanges, and SMSF compliance.
Browser-based profit & loss calculator for Meteora DLMM liquidity positions on Solana. Tracks deposits, withdrawals, fee claims, and impermanent loss per position. Runs entirely client-side with IndexedDB and sql.js.
A delta-neutral strategy simulator: feed strategy params and market data, and a generator derives the full trade ledger plus a scrubbable PnL timeline. Generator-first — the ledger is regenerated from rules, never hand-edited, and stays delta-neutral by construction.

I write about building crypto and financial-data tools — and what I learn using AI to ship more on my own.
