Liam Faruq

Senior Engineer · Rust / Solana · DeFi & Trading Infrastructure

I build and ship Solana programs and the Rust backends behind them — and consult on both.

Anchor programs, vault architecture, liquidation engines, prediction-market and trading infrastructure — with deep integrations across Solana DeFi: Jupiter (perpetuals, lending, predictions), Orca, Meteora, Raydium, Kamino, and Phoenix. I contribute to open source in the Rust/Solana stack, and consulting runs through my UK company, EpochFi Labs Ltd.
