I’m developing a cross-platform productivity app for Android and iOS and need an experienced Flutter developer who can take it from polished prototype to store-ready release. The emphasis is on performance, scalability, and a clean, intuitive UI that feels at home on both platforms. Mainly kotlin work Core scope You will implement the key productivity modules and wire them together with robust state management, push notifications, and AI-assisted logic. The selected features are: • Task management • Calendar integration • Collaboration tools • AI layer with smart task suggestions and predictive scheduling Beyond these modules, the build must cleanly consume our existing REST APIs, gracefully handle offline states, and keep animations silky-smooth even on mid-range devices. Deployment & compliance Part of the mandate is to configure signing, build pipelines, and App Store / Play Store assets so we glide through submission reviews without surprises. Deliverables are considered complete when: 1. Both Android and iOS releases pass internal QA for speed, memory footprint, and UI consistency. 2. AI suggestions and predictive scheduling respond in under one second on common test devices. 3. Stores accept the binaries on first submission, with push notifications and in-app purchases (if any) functioning in production. If you thrive on crafting beautiful Flutter code and ship confidently to both stores, let’s get started.
