Rockstar🎓
Top SchoolTobin Harding is a Rust-focused Bitcoin maintainer and systems programmer with 11 years of experience building secure, high-assurance software for crypto and Linux ecosystems. He currently works on institutional cryptocurrency wallet design using Intel SGX and maintains core rust-bitcoin projects with funding from Riot/Kraken, reflecting deep open-source stewardship. His background spans atomic-swap protocol work, Lightning and ERC-20 integrations, and kernel-level contributions to Linux and OpenZFS, showing fluency from userland services to kernel patches. An advocate for code quality, he consistently improves maintainability across major Rust projects (bdk, rust-secp256k1, electrs, miniscript), and has a track record of adding tests and fixing subtle bugs. Based in Sydney, he blends academic rigor (BSc and graduate CS credentials) with practical apprenticeship and community leadership as founder of the Central Coast Linux Users Group. Notably, his contributions range from low-level kernel fixes to cryptographic wallet mechanics, a rare cross-section in the Bitcoin tooling landscape.
