...together, including any required APIs, database tables, and payment gateway hooks. Look & feel The interface has to be colorful and vibrant—think lively imagery, bold accents, and intuitive gestures that make the ordering process fun rather than clinical. Please apply material-design best practices so the palette remains consistent across screens and animations feel native. Tech expectations Native Kotlin is preferred, though a high-performance cross-platform toolkit such as Flutter is acceptable if it does not restrict Android-first optimizations. Use Firebase, AWS, or an equivalent real-time backend for authentication and order status pushes.

I need a seasoned mobile engineer to retrofit a proper offline-first caching layer into my production iOS (Swift) and Android (Kotlin) apps. Right now every launch triggers a full download from our REST API, which slows everything down. Your job is to persist both textual content and images to the device on first load, then switch to a lightweight delta-sync that only fetches items that are new, updated, or deleted. Scope of the screens that must work seamlessly from cache: Home, Map details, Services, Articles, General Information, plus all related detail pages and their images. Once the data is stored locally, navigation should feel instant, without flash-of-loading screens, even after the user force-quits and reopens the app or loses connectivity. I’m open to the most app...

I’m building my first Android application and quickly realised I still have a lot to learn. I’d like an experienced Android developer to team up with me, write clean, well-documented code, and explain the thought process along the way so I can level up while we ship a working app. Here’s what I have in mind: • A simple, native Android project (Java or Kotlin) set up with solid architecture I can reuse. • Core screens, navigation, and data handling implemented and clearly commented. • Short walk-through notes or quick screen-share recordings after each milestone so I understand each decision. The Git repository, build-ready source code, and your explanatory notes will serve as the final deliverables. If this sounds straightforward to you and you...

I need an experienced mobile app developer to build a complete Android application from the ground up. My focus is solely on the Android platform at this stage—no iOS version is required right now—so you should be comfortable working in Kotlin or Java and familiar with Android Studio, Material Design, and the latest SDK standards. The core idea and feature set are ready to be refined, and I’m looking for guidance on translating those requirements into a clean, performant build. If you have suggestions on architecture or third-party integrations, I’m open to hearing them; however, the final product must run smoothly on current Android OS versions and be submission-ready for Google Play. Deliverables: • Full Android Studio project with well-commented sou...
