Garden Finance
Sep 2024 — Present (2y 2m)Backend and solver infrastructure powering Garden's cross-chain swap protocol. $2.3B+ settled across 15+ chains with sub-minute swap execution.
- Led cross-chain integrations for Starknet, Solana, and XRPL, extending Garden's settlement infrastructure to new chains.
- Architected Garden's V2 API, opening the protocol to external integrators (Li.Fi, Rango, Phantom, and 30+ others), now powering $110M+ in third-party volume.
- Engineered Garden's solver, a concurrent Rust market maker that prices and fills cross-chain swaps from live market data in real time, routing execution across Jupiter, CoW Swap, Uniswap, and Astra Markets while managing inventory and exposure.
- Built the solver's Binance and Hyperliquid integrations across their market-data and order APIs: spot markets for cross-venue inventory rebalancing, and USD-margined perpetuals for delta-neutral hedging and price protection.
- Implemented WebAuthn passkey sign-in (Face ID and Touch ID) for the Garden app.
- Prototyped a MetaMask Snap bringing Garden's cross-chain swaps directly into MetaMask.
selected engineering work
One-command localnet framework for EVM, Solana, Starknet, Bitcoin, Litecoin, and zkSync: reproducible blockchain environments for integration testing and CI. Each network boots with pre-funded accounts, a unified faucet, and contracts pre-deployed at fixed addresses, exposed through a Rust testkit library with first-class CI integration and per-chain block explorers.
