Worked on the 0xbow-io/privacy-pools-core repository, delivering features to enhance blockchain contract interactions and ERC20 withdrawal flows. Developed and improved the ContractInteractionsService using TypeScript and Solidity, enabling reliable deposit, withdrawal, and relayer management with robust error handling and cryptographic correctness. Implemented a brute-force commitment recovery service to restore lost commitments, and enforced SNARK secret generation bounds for secure cryptographic operations. Expanded unit testing and documentation to support maintainability. Later, introduced relayer gas funding for ERC20 withdrawals via Uniswap integration, and streamlined developer onboarding with comprehensive README updates, demonstrating expertise in backend development, blockchain interaction, and API design.

Feb 1, 2025February 2025 — 0xbow-io/privacy-pools-core: Key deliverables focused on contract interaction reliability, recovery capabilities, and cryptographic correctness. Delivered enhancements to ContractInteractionsService (ABIs for IEntrypoint, IPrivacyPool, IPrivacyPoolSimple; deposit/withdrawal/relay/ragequit management; approveERC20 with ERC20 token support; improved error handling), enabling seamless ERC20 approvals and safer user flows. Implemented brute-force commitment recovery service to recover lost commitments by iterating candidate values within a range, with timeout controls and decimals handling. Expanded test coverage and documentation for ContractInteractionsService to raise reliability and maintainability. Enforced SNARK secret generation bounds by applying modulo with SNARK_SCALAR_FIELD to ensure cryptographic operations stay within the field.
