I need a mobile developer to bring my existing app up to the latest platform version and smooth out any issues the update introduces. This first step is strictly a maintenance pass—no payment is attached to it. Once the upgrade is stable, I will open a paid phase to add new AI-driven matching features. Please show me tidigare arbete—examples of past mobile projects where you performed successful version migrations or similar fixes. Initial deliverables • Rebuild the app on the newest SDK or framework version with zero build errors. • Resolve any crashes, broken functionality, or noticeable slow-downs created by the upgrade. • Supply a concise change log summarising what you adjusted and why. If you’re comfortable starting with this unpaid phase and would like to be first in line for the upcoming paid AI work, let’s talk.
