I’m launching a new product and need one reliable partner who can take charge of everything: the public-facing website, the mobile apps, and the backend that ties them together. I’m still flexible on specific technologies—whether the first release lands on iOS, Android, or both, and whether you prefer React, Angular, Vue, or another modern framework—but the stack you choose must be maintainable, well-documented, and performance-oriented. Scope of work • Recommend an end-to-end architecture for web, mobile, and API layers • Build secure authentication, data sync, push notifications, and payment modules once we lock the feature list • Create an intuitive admin panel so I can manage users and content without touching code • Configure CI/CD pipelines and handle deployment to the App Store, Play Store, and a cloud host • Deliver clean, commented source code plus concise setup and release documentation Acceptance criteria 1. Web app loads in under three seconds on 4G and clears basic Lighthouse audits 2. Mobile app passes store review and runs smoothly on current iOS and Android versions 3. Backend endpoints include automated tests covering at least 80 % of logic 4. README explains local setup, environment variables, and release steps in plain language Show me links or screenshots of complete products you’ve shipped and a short note on the stack you would propose. I value clear communication and predictable delivery, and I’m ready to move quickly with the right fit.
