Worked on the hiero-ledger/solo repository to implement comprehensive unit tests for the ExplorerCommand feature, focusing on improving code reliability and ensuring that functionality aligned with project requirements. Applied TypeScript and software testing best practices, leveraging test-driven development to strengthen test coverage and reduce the risk of regressions. Integrated these tests directly into the repository, supporting continuous integration readiness and enabling faster debugging and safer future refactors. Demonstrated proficiency in unit testing and Git workflows, including signed-off and co-authored commits, while collaborating effectively with team members to maintain code quality and support ongoing development efforts throughout the project.
