Worked on the BitGoJS repository to enhance Ethereum and Go staking workflows using TypeScript and backend development skills. Delivered an update to the sdk-core module by introducing an unstakeAll flag to the EthUnstakeOptions interface, allowing developers to explicitly indicate full asset unstaking in Ethereum staking flows and reducing ambiguity in API usage. Later, implemented cryptographic signature enforcement for Go staking final options, addressing a validation gap that previously allowed unsigned transactions. This change improved transaction integrity and auditability by requiring signatures in the final options path. Focused on SDK development and testing, the work emphasized security and developer experience.
