The case documents the diagnostic; Kotlin/KMP are evolution recommendations. [Review the case and delivered scope](/en/cases/maderaplus-technical-diagnostic) Diagnostic staging with anonymised data. 203 documented backend/API calls. 115 issues reviewed and 23 prioritised actions. Tell me about the project ## Tell me what needs to be resolved. Objective, current state and timing are enough to assess fit and suggest a concrete starting point.

[Discuss maintenance](#landing-contact) ## Common maintenance needs To start, I need repository access, a reproducible environment, publication context and someone who can validate changes. 01 ### Recurring errors Bugs, regressions or fragile behavior in important application flows. 02 ### Evolutives New functionality, API changes, UX improvements or product adaptations. 03 ### Release and publication Version preparation, risk review and support through the production release. ## How work is ordered Continuity needs a simple operating frame so every request does not become an emergency. 01 ### Initial diagnostic Reproducible build, application state, dependencies, visible debt, publishing access and critical flows. 02 ### Priorities Backlog, validation owner and criteria to separate urgent fixes from planned improvements. 03 ### Follow-through Small deliveries, tests, change notes and clear release and rollback criteria. ## Common Questions The minimum worth clarifying before opening a collaboration. Can you maintain an app you did not build?+ Yes, when repository access, a reproducible environment, minimum context and a validation owner are available. Is this a retainer or a fixed project?+ It can be a retainer for recurring work or a fixed project for a specific release or evolutive. Do you also review publication?+ Yes. I can cover the checklist, tests, risk closure, release notes and publication support. ## Keep Comparing If you are still comparing options, these routes help narrow the decision.
