How to write yours — Blockchain Developer tips

Name specific blockchain platforms, languages (Solidity/Rust), and protocols you've worked with—vague 'blockchain experience' signals lack of depth.
Quantify impact with technical metrics: gas savings %, transaction throughput improvements, or security audits completed rather than generic accomplishments.
Demonstrate knowledge of the company's specific technical stack or research direction (mainnet choice, consensus layer, DeFi/NFT/enterprise focus) mentioned in the posting.
Reference your GitHub, deployed contracts, or audited code publicly—blockchain work is verifiable and expected to be shown, not just described.
Address security-consciousness explicitly: mention vulnerability testing, formal verification, or audit experience, as security is non-negotiable in blockchain roles.
