I’m building a practical, no-frills utility app and need an experienced mobile developer to take it from concept to store-ready release. The core of the product is its messaging system, so real-time chat performance, secure data handling and an intuitive conversation view all need to be rock-solid. Here is what I expect: • A clean, modern UI that keeps the focus on the tool’s primary purpose while letting users swap messages seamlessly. • Stable builds for both iOS and Android (React Native, Flutter or the native stacks—choose the approach you work fastest and most reliably with). • User account creation with simple email or phone verification. • Cloud-based back-end for message storage and push notifications; Firebase or an equivalent scalable solution is fine, as long as setup is documented. • Hand-over of full, well-commented source code, build instructions and a short README so future maintenance is straightforward. Once you join, I’ll share wireframes and a concise feature list so you can provide milestones and timelines. I’m happy to iterate quickly, test weekly builds and give prompt feedback so we keep momentum high. Let’s craft a lightweight utility app that delights users with its chat feature and ships on schedule.
