Cross-Platform Mobile App Development
I build mobile clients that fit the product's backend, account model and security needs across Android and iOS.
What this service covers
I build mobile clients that fit the product's backend, account model and security needs across Android and iOS.
- Cross-platform app flows and responsive mobile UI
- Authentication and secure session handling
- API integration and real-time or push updates
- Local state and offline behavior where useful
- Payments or account features tied to backend rules
- Build and release preparation
How I build it
A mobile app must handle intermittent connectivity, app lifecycle changes and smaller screens without losing important user state. I define the core journeys and API contracts before choosing React Native or Flutter.
The Qbitcoin project included a React Native mobile wallet alongside node and explorer interfaces. MetaLLM has an Android app as part of its broader AI product.
Engineering decisions
Sensitive operations should be enforced by the backend, while the client stores the minimum data needed for a usable experience. Offline support is scoped to the actions that truly need it.
The best framework depends on existing team skills, platform-specific needs and integration requirements; I do not assume one stack fits every application.
Related project work
Qbitcoin and MetaLLM provide mobile product context, while their case studies explain the connected systems.
Technology and scope
React Native and Flutter appear in my documented project work, alongside REST APIs, PostgreSQL and Node.js backends.
Getting started
Share target platforms, main user journeys, designs if available, existing APIs and any offline or security requirements. I can scope a practical first release.
