I will debug and stabilize your laravel or PHP app with regression tests


About this gig
I investigate and stabilize existing Laravel and PHP applications by reproducing the problem, tracing the root cause, making the smallest safe change, and adding regression evidence.
Typical scope includes:
exceptions and unexpected behavior
validation, authorization, and state-transition defects
database, API, queue, CSV, and integration problems
focused performance and timeout investigation
regression tests and verification notes
My public Laravel/Vue reference includes CSV import, row-level validation, reporting, authorization, layered domain/API/UI tests, static analysis, and a documented 25-item development defect log.
You receive the root-cause explanation, scoped code changes, tests where practical, and written verification steps. I work asynchronously and do not require video meetings.
Please send the framework and PHP version, reproduction steps, expected behavior, logs with secrets removed, repository area, test commands, deployment constraints, and acceptance criteria. Production deployment and unrelated feature work are separate scope.
