Cross-Platform App Development Team in Argentina

Case study: Retail loyalty app delivered in 14 weeks

A retail group needed to replace two separate native apps with one cross-platform product that could scale before peak season. We formed a squad (product owner, UX designer, 2 React Native engineers, 1 backend engineer, QA automation) and shipped in phased releases.

• First production release in 6 weeks, full rollout in 14 weeks.
• 38% reduction in mobile maintenance effort after consolidating duplicated native logic.
• Crash-free sessions improved from 97.9% to 99.4% with automated test coverage and observability.

The key was not just framework choice, but execution discipline: clear acceptance criteria, performance budgets, and store-readiness checklists for every sprint.

React Native Development

Ideal for teams that need rapid feature delivery with strong JavaScript/TypeScript velocity. We use native modules only where they create real value, and align implementation with official React Native best practices for navigation, performance, and release builds.

Flutter Development

Great for product teams prioritizing consistent UI and smooth interactions across devices. We structure Flutter projects for long-term maintainability, with clear state management conventions, code quality gates, and automated testing pipelines.

Code Sharing Strategy

We define clear boundaries for shared UI, business logic, and platform-specific capabilities. This avoids the common anti-pattern of forcing 100% shared code where native behavior is required. The result: healthier codebases and more predictable releases.

Platform-Specific Features

Biometrics, camera flows, push notifications, deep links, and payment SDKs often need native-level decisions. We implement these carefully so your app still feels natural on each platform while preserving as much shared code as possible.

Performance Optimization

Our developers understand cross-platform performance: they know how to optimize app performance on both iOS and Android, handle platform-specific performance considerations, minimize memory usage, optimize rendering, and build cross-platform applications that perform well on both platforms. They've built cross-platform apps that are fast and responsive on both iOS and Android.

Native Integration

Our developers understand native integration: they know how to integrate cross-platform apps with native iOS and Android features, handle platform-specific APIs, use native modules and platform channels effectively, and create cross-platform applications that can access device features like cameras, GPS, and sensors. They understand how to bridge the gap between cross-platform and native development.

Testing & Quality

Our developers understand cross-platform testing: they know how to write unit tests and integration tests for cross-platform apps, test on both iOS and Android devices, handle platform-specific test scenarios, and ensure cross-platform applications work well on both platforms. They build cross-platform apps that are not just functional, but also reliable and maintainable.

What Makes a Cross-Platform App Developer

When we say "cross-platform app developer," we mean developers who:

• Understand cross-platform frameworks: They know how to use React Native, Flutter, and other cross-platform frameworks effectively
• Share code effectively: They understand how to share code between iOS and Android while maintaining quality
• Handle platform differences: They know how to handle platform-specific features and maintain platform-specific UI/UX guidelines
• Optimize performance: They know how to optimize app performance on both iOS and Android platforms
• Write testable code: They understand how to write unit tests, integration tests, and test cross-platform apps on both platforms

Code Sharing

Shared modules reduce duplicate implementation work and keep product behavior aligned between platforms. Most teams see meaningful gains in delivery cadence when shared architecture is planned early.

Faster Development

One coordinated squad can plan, build, test, and release for both stores. That shortens feedback loops and helps product teams validate hypotheses earlier.

Cost Efficiency

Operating one core codebase reduces duplicated QA, release, and maintenance effort. That usually improves total cost of ownership over the product lifecycle.

Native-Level Experience

With proper architecture, performance budgets, and native integrations where needed, cross-platform apps can deliver smooth UX and stable production behavior at scale.

What You Can Build with Cross-Platform App Developers

Cross-platform app developers can build:

React Native Development

Best fit for teams with strong TypeScript practices, frequent UI iteration, and rapid release goals. We follow official guidance from the React Native ecosystem and optimize bundle size, startup time, and navigation performance.

Flutter Development

Strong choice when product teams want pixel-consistent interfaces and robust rendering control. We set up reusable component architecture, testing layers, and release pipelines for sustainable growth.

.NET MAUI and Xamarin Modernization

For teams with existing Xamarin codebases, we support migration paths to .NET MAUI, preserving business logic while modernizing UI and release tooling.

Platform Integration

We integrate secure auth, push notifications, camera, geolocation, biometrics, and payment providers while meeting app-store and platform quality requirements.
