Summary
🤩
Rockstar🎓
Top SchoolRakan Al-huneiti is a Senior Protocol Engineer with 13 years of hands-on experience building distributed systems and nine years focused on high-scale backend and blockchain infrastructure. He has led protocol and core development at organisations like Enjin and Parity, contributing to Polkadot/Substrate internals and key keystore/offchain signing features used by the ecosystem. Currently at Chainway Labs he’s building an EVM-compatible ZK rollup on Bitcoin using Rust and Risc0, bridging rollup and Bitcoin data-availability designs. Rakan combines deep Rust and Python expertise with practical security work on cryptographic signing and keystore integrations, and has contributed to well-known open-source projects including Substrate, Polkadot SDK and the Raiden Network. He also brings full-stack instincts from earlier work—ranging from Emacs tooling to large-scale backend systems at Souq and NewStore—which helps him navigate both developer ergonomics and low-level protocol concerns. Colleagues describe him as a systems-first engineer who moves fluidly between protocol design, secure signing primitives, and production-grade implementations.
