Rockstar🎓
Top SchoolAleksandar Brayanov is a blockchain engineer with eight years of technical experience and over four years focused on building scalable decentralized protocols using Rust, Substrate, TypeScript, and Solidity. He has a strong track record of shipping production-grade runtime and EVM-integration work—enabling full EVM compatibility for multiple Substrate projects and implementing Ethereum RPC and custom precompiles. Aleksandar’s contributions include a Merkle tree rewards system capable of distributing to 500+ million addresses and an offline marking mechanism that reduced inactive collator participation to two days on a live L1. He combines protocol-level engineering with security-minded upgrades and tooling (Chopsticks, Zombienet) to streamline cross-chain logic and runtime upgrades. Based in Salford and holding a BSc in Artificial Intelligence from Manchester, he’s particularly interested in the intersection of decentralized networks and AI, bringing both deep protocol expertise and practical deployment experience.
