Full-Stack Cross-Platform App Development

I have an application concept that must launch simultaneously as a responsive web app and as mobile installs on both iOS and Android. I’m looking for one experienced full-stack developer who can own the build end-to-end—database design, API layer, front-end implementation, and store deployment—while advising me on the most suitable tech stack.

Here’s what I need from you:
• Architect and implement a shared back-end that serves both the browser version and the mobile builds.
• Develop the web interface so it works flawlessly on desktop and mobile browsers.
• Produce companion apps for iOS and Android from the same codebase (React Native, Flutter, or a comparable cross-platform framework—open to your recommendation).
• Configure basic CI/CD, staging, and production environments, then guide submission to the App Store and Google Play.
• Deliver clean, well-commented source code plus concise setup documentation so my team can maintain it going forward.

We’ll start with a quick discovery session to finalise the feature set, after which I’d like to work in milestone releases that we can test together. If this sounds like a build you can drive confidently, let’s discuss your approach and timeline.
