Over five months, contributed to ethereum/hevm by building and refining symbolic execution features, error handling, and developer tooling for EVM smart contract analysis. Focused on robust input discovery, assertion testing, and partial execution path reporting, the work improved test coverage and debuggability. Enhanced the CLI and RPC systems with persistent caching and clearer messaging, while strengthening ABI encoding/decoding and integer handling. Addressed error diagnostics for precompiles and FFI, reducing crashes and improving user feedback. Leveraged Haskell and Solidity, applying formal verification, code refactoring, and functional programming to deliver maintainable, future-proof infrastructure supporting smart contract development and automated testing.
