Summary
🤩
RockstarAge Manning is a founder and seasoned backend engineer based in Sydney with a decade of experience building robust, production-grade distributed systems. With a PhD background in theoretical particle physics, he blends deep analytical rigor with practical software engineering, having co-founded Sigma Prime and contributed to prominent open-source projects. His work on rust-libp2p improved core networking behavior—adding configurable inactivity timeouts, message signing, and Gossipsub v1.1 support—while addressing race conditions and protocol correctness. At Lighthouse he strengthened Ethereum validator client functionality, replacing services with tokio timers, expanding RPC support, and hardening attestation and peer-interaction logic. He’s comfortable operating at the protocol level and shipping low-level, safety-critical changes in Rust that power decentralized networks. Colleagues rely on him for tough backend challenges that require both research-grade thinking and pragmatic engineering.

The Rust Implementation of the libp2p networking stack.
Role in this project:Back-end Developer
Back-end DeveloperContributions:77 reviews, 17 commits, 41 PRs in 2 years 11 months
Contributions summary:Age primarily contributed to the core networking functionality of the libp2p Rust implementation. Their work focused on enhancing the `OneShotHandler` by allowing for configurable inactivity timeouts and adding features such as message signing, and support for Gossipsub v1.1. These changes include significant modifications to the core protocol, handling control messages, and implementing core features like message validation. They also refactored existing code to improve efficiency and address potential race conditions.
