PROFILE

Simeon Nakov

Simeon Nakov contributed to the hiero-json-rpc-relay and hiero-local-node repositories by delivering features that enhanced EVM compatibility and streamlined asset distribution. He led a codebase-wide refactor to standardize address terminology, replacing all instances of 'eth-address' with 'evm-address' to clarify EVM support and improve maintainability. In hiero-local-node, he implemented frictionless airdrop functionality, automating asset distribution logic. Simeon also integrated HIP904 smart contract tests into CI pipelines and added HRC904 token standard support in the Hedera Token Service. His work demonstrated depth in backend development, Solidity smart contract engineering, and CI/CD automation using TypeScript and GitHub Actions.
