PROFILE
Geoff Little
Graham Little developed scalable, read-heavy database workflows for the pragma-org/amaru repository, focusing on enabling safe, concurrent, read-only access to the ledger and chain databases. He refactored the storage layer to support multiple backend types, introducing generic internal mechanisms and separating read and write responsibilities through new ReadOnlyChainDB and ReadOnlyChainStore abstractions. Using Rust, he optimized data access patterns and updated helper utilities to support efficient multi-reader scenarios, reducing transaction overhead while maintaining data consistency. His work included updating tests for reliability on read-only RocksDB stores, reflecting a deep understanding of concurrency control, database management, and robust software design.
