Built a low-latency Block Root Archive service in Rust (gRPC/Tonic) for efficient cross-chain proof validation under high-throughput conditions. Designed a blockchain data indexing pipeline (Rust, SQLx, PostgreSQL, Axum) serving on-chain events with sub-second query latency. Leveraged async Rust (Tokio) to handle concurrent data ingestion and RPC requests with non-blocking execution. Developed a high-throughput RPC client with batching, retries, and structured error handling to manage node failures and degraded responses. Tested Ethereum JSON-RPC pipelines (mempool, transaction lifecycle, edge cases) and built Python automation (web3.py) for validation. Debugged critical issues in RPC handling and transaction execution, improving backend reliability.

Developed Move smart contracts on Aptos for account management and lending logic with secure state transitions. Integrated fungible and non-fungible token standards into production-ready modules.
