Inherited codebases often hide critical bugs behind layers of spaghetti logic. In this session, I take you through the journey of tackling a monolith plagued by database concurrency conflicts and object mapping on object mapping on more object mapping that stripped away essential context.

Rather than a full rewrite, we used GitHub Copilot CLI to analyze the chaos and follow the individual strings of spaghetti. By leveraging Aspire's built-in distributed tracing and structured logging, we finally gained visibility into the flow of data, pinpointing exactly where concurrency broke and where context was lost.
