Top SchoolDaniel Werner is a Principal Software Engineer with 14+ years building performance-sensitive backend and data systems, currently working on Rust-based indexing and high-throughput data pipelines for The Graph at Edge & Node. A self-taught engineer and independent consultant, he has repeatedly delivered large efficiency gains—e.g., cutting Patricia Merkle Trie disk growth by ~80% and improving smart contract runtime performance by 450% at CasperLabs. His work spans systems, blockchain, and streaming data (Arrow Flight), with deep practical expertise in Rust, ingest/performance optimization, and scalable architecture. An active open-source contributor, he’s implemented client RPC features for the Casper network and maintains critical indexer components, demonstrating both low-level systems chops and production-focused engineering. He prefers solving hard backend bottlenecks and building robust tooling that scales from prototype to mainnet.

Contributions summary:Daniel primarily contributed to the development of the Casper client, focusing on adding functionality for retrieving balance information. This involved creating a new `get-balance` subcommand, implementing the associated client-side logic and integrating it with the Casper node's RPC interface. Refactoring of the codebase was also done to improve modularity and organization, and RPC functionality was implemented using trait-based design. This included modifying existing client-side code.
