I need a complete software-development effort to turn my commissioning workflow into a polished mobile app that runs smoothly on both iOS and Android. The core idea is simple: give field teams a single place to handle every commissioning step—logging equipment data, checking tasks off in real time, and instantly generating the completion reports we submit to clients. Because the project centres on full-cycle software development, I’m expecting you to handle architecture choices, clean UI/UX for technicians, API integrations (if you prefer a cloud back end, I’m open to Firebase, AWS or similar), and store deployment. I’m happy to supply existing process docs, sample spreadsheets and branding assets the moment we kick off. Key acceptance points • One code-base targeting iOS and Android (Flutter, React Native, Kotlin Multiplatform or your preferred approach) • Offline data capture with automatic sync once a connection returns • Secure user sign-in plus role-based access for managers and technicians • PDF or Excel report export pulled directly from the logged data • A short admin panel (web or in-app) so I can update task lists without releasing a new build Hand-over isn’t complete until I can install a test build from TestFlight and Google Play internal track, run through each commissioning scenario, and see the export match our current manual report. If this sounds like the kind of build you enjoy, let’s talk timeline and milestones.
