Worked on improving the codebase of tarantool/tt by focusing on code quality and maintainability rather than feature development. Addressed a static analysis warning by removing a redundant Docker case from the CreatePacker switch, which previously duplicated the default nil return behavior. This change reduced unnecessary branching and clarified the control flow, making the packing logic easier to understand and maintain. Utilized Go for the implementation, applying skills in code refactoring and static analysis to enhance reliability and readability. The work contributed to a cleaner codebase, lowering the risk of future regressions and supporting ongoing development efforts in the repository.
