Multi-Chain DeFi Data Pipeline (Solana / ETH / BSC)

Large-scale on-chain data collection and analytics infrastructure across three networks: Solana, Ethereum, and BSC. The goal was to build a fast, proprietary analytics database rather than relying on third-party explorers.

Started with deploying historical archive nodes per network. Then built a parametric bulk ingestion system using NATS as the message broker and ScyllaDB for storage — fast enough to handle the volume without falling behind. Reporting and dashboards were built on top of ClickHouse.

Tech Stack: Rust, NATS, ScyllaDB, ClickHouse, Solana, Ethereum, BSC
