Project description:
"I’m ready to turn a clear concept for a crypto-focused utility into a polished, store-ready app available on both iOS and Android. The core idea is to give everyday users a reliable mobile tool that simplifies their interaction with cryptocurrencies—think portfolio tracking, real-time price data, secure wallet connectivity, and friction-free transactions or transfers.

What I have so far
• A detailed feature map outlining each screen, its purpose, and the flow between them
• Preferred design cues (light / dark theme, minimalist UI) and color palette
• Shortlist of third-party APIs for market data, wallet authentication, and on-chain analytics

Where I need your expertise
• Advising on the most efficient cross-platform stack (Swift + Kotlin, Flutter, React Native—open to your recommendation)
• Building the complete front-end experience with smooth, native-feeling performance
• Integrating the chosen crypto APIs securely—OAuth, token management, and encryption must be handled properly
• Standing up any lightweight backend or cloud functions required for user data, push notifications, or analytics
• Testing on a representative device matrix, fixing edge-case bugs, and preparing both builds for App Store and Play Store submission (including screenshots, descriptions, and compliance checks)

Deliverables
1. Full source code in a private Git repo, cleanly documented
2. Production-ready iOS (.ipa) and Android (.aab) builds
3. Setup docs covering environment, API keys, and deployment steps
4. A concise test report with device list, scenarios covered, and results
5. Post-launch support for the first round of user feedback (bug fixes only)

Acceptance criteria
• App passes App Store and Play Store review on first submission
• Wallet connection and market data refresh complete in <3 seconds on a 4G connection
• No critical or major crashes in Firebase Crashlytics after one week of live usage

If you excel at secure mobile development and have shipped crypto or finance utilities before, I’d love to see what you can bring to this project." (client-provided description)
