I will investigate and fix one agreed issue in an existing tRPC procedure, Prisma query or API integration. Examples include validation, request or response handling, query behaviour, or connecting an app to an existing endpoint. Please message me before ordering so I can review the issue, confirm the scope and agree on the expected result. Included: - One existing procedure, query or integration flow - The scoped code change and relevant verification - A short explanation of what changed - One revision against the original agreed requirements Destructive database migrations, production data repair, authentication redesign, new backend systems and large performance investigations need a separate scope. Delivery is through messages and code handoff. To get started: Relevant code, setup steps, schemas or API docs, reproduction steps and expected behaviour. Use test data and confirm scope before ordering.
