INTERMEDIATE
Build production-grade data pipelines that ingest, transform, and serve on-chain data — from raw blockchain events to analytics-ready DeFi metrics.
Understand the data engineer's role, the ETL pipeline pattern, and the storage hierarchy that underpins all data platforms.
Map the layers of on-chain data, understand the trade-offs between nodes, RPC providers, and indexers, and decode events and traces.
Choose between streaming and batch, transform raw blockchain data into analytics-ready tables, and enforce data quality at every stage.
Design layered data warehouses, model canonical DeFi metrics like TVL and volume, and package data as products served via APIs.
Handle the blockchain-specific challenges of reorgs and chain reorganisations, instrument pipelines for observability, and architect for scale.
