PROFILE

Simeon Nakov

Worked on backend and smart contract development across the hiero-json-rpc-relay and hiero-local-node repositories, focusing on EVM compatibility and asset distribution automation. Delivered a codebase-wide refactor in Go and TypeScript to standardize address terminology, improving maintainability and preparing for future EVM-related features. Implemented frictionless airdrop functionality and integrated HIP904 contract tests into CI pipelines using GitHub Actions and Solidity, enhancing reliability and test coverage for Hedera smart contracts. Added HRC904 token standard support with new airdrop methods and comprehensive tests, strengthening the Hedera Token Service. Prioritized code standardization, automation, and robust testing without introducing customer-facing changes.
