Summary
🤩
Rockstar🎓
Top SchoolRyan Schneider is a Staff Backend Engineer with 17+ years building and operating Linux-backed distributed systems at scale, currently focused on backend and infra roles in the Ethereum and cloud-native space. He has deep hands-on experience in Go, Terraform/Pulumi, and production ownership—scaling INFURA services to billions of requests and contributing performance improvements to high-profile Ethereum clients like go-ethereum, Erigon, and Reth. Comfortable across languages and domains from iOS signal-capture work in Swift to low-level C/C++ systems, he combines SRE rigor with software craftsmanship learned leading PlayStation Now infrastructure and live game operations. Ryan’s open-source footprint highlights a knack for reducing contention, optimizing RPCs, and adding pragmatic caching and MEV/RPC features in blockchain clients. He prefers owning the full lifecycle—design, deploy, and run—and often surfaces non-obvious wins: subtle concurrency fixes and test coverage that measurably improve production reliability. Based in Southern California, he blends a generalist’s curiosity with specialist impact in backend performance and resilient infrastructure.

Modular, contributor-friendly and blazing-fast implementation of the Ethereum protocol, in Rust
Role in this project:Back-end Developer
Back-end DeveloperContributions:35 reviews, 14 PRs, 55 comments in 1 year 8 months
Contributions summary:Ryan primarily contributed to the implementation and enhancement of features within the Reth Ethereum client. Their work involved fixing issues related to port reuse in network tests and implementing new RPC methods, specifically `reth_getBalanceChangesInBlock` and several new Flashbots RPC methods related to builder validation, including V3 and V4, along with other MEV improvements. These changes touched on core components like RPC modules, the state database, and the MEV (Miner Extractable Value) API, highlighting a focus on Ethereum protocol implementation and optimization.
