I build the systems under on-chain apps: native/Anchor Solana programs, indexers, transaction infrastructure, and the high-throughput backends and APIs around them. TypeScript-first, strong Rust for the parts where performance decides the outcome. Currently building data infrastructure for Solana. Previously: lead engineer shipping DeFi products end-to-end (lending, staking, NFT marketplaces), and Anchor program security auditing.
Recent work:
- Anigacha — provably-fair on-chain NFT lottery. Native Pinocchio, Switchboard VRF, zero-copy chunked custody, grind-proof refunds.
Interested in: low-level Solana, DeFi infra, trading systems. Reach me: Telegram @OxKaoru
