Got one SaaS bug blocking a release or breaking a core workflow? I’ll reproduce it, trace the failure across the backend, API, database, authentication, or integration layer, and deliver a tested fix with a clear root-cause note. This service covers one reproducible issue in an existing codebase—not a bundle of unrelated bugs or a new feature build. What’s included: • Reproduction steps and a concise root-cause summary • Targeted code, configuration, or database fix • Regression test or repeatable verification steps • Error-handling or logging improvement when relevant • Patch notes plus deployment and rollback guidance Send me the error, reproduction steps, logs, and current setup. I’ll tell you the cleanest way to fix it.
