Worked on the hhru/frontik repository to enhance JSON handling and improve asynchronous task reliability using Python. Developed a feature that extended JSON serialization by decoding bytes into UTF-8 strings and introducing an optional sort_keys parameter, allowing for more flexible and predictable data output. Addressed a bug in asynchronous programming by ensuring that run_async_task correctly returns the result of awaited coroutines, which supports reliable task chaining and error handling. Expanded test coverage to validate both the new JSON encoding behaviors and async task results, strengthening backend development practices and reducing the risk of regressions or silent failures in downstream processes.
