How We Onboard Your Cross Platform Developer
Most engagements move from initial requirements to active development within 3 to 5 business days, with no lengthy discovery phases, no extended onboarding cycles before anything gets built.
Share Your Requirements
Tell us your target platforms, preferred framework, team size, and project stage we scope the right fit from there.
Developer Matching
We align a Flutter, React Native, or Kotlin Multiplatform developer to your stack, product type, and working timezone.
Trial & Alignment
Review the developer's code approach and communication on a real backlog task before committing to a longer engagement.
Active Development
Your developer joins your sprint, integrates into your tools, and begins contributing to production work from day one.
Cross Platform Products We've Shipped
A React Native Mobility App Built for Fleet Dispatch Across iOS & Android
We built the CarGator driver and customer apps in React Native for iOS and Android, integrating WhatsApp-triggered dispatch, real-time fleet coordination via Socket.IO, and an operator admin panel deployed across GCP and AWS. The entire mobility stack customer app, driver app, and admin portal were delivered from a single React Native codebase, cutting development effort while maintaining full platform parity across iOS and Android.
Hire when building visually consistent apps for iOS and Android with a single Dart codebase, Riverpod state management, and platform channel integrations.
Hire when your team already works in JavaScript/TypeScript and needs a mobile app that leverages an existing web component library or REST/GraphQL APIs.
Hire when you want to share business logic across iOS and Android while keeping platform-specific UIs native, ideal for performance-sensitive or regulated products.
Framework-Specific Depth
Our Flutter developers work with Riverpod, GoRouter, and Isar, not just the basics. Our React Native engineers are fully migrated to the New Architecture (JSI/Fabric) and don't carry Xamarin or Cordova baggage from a previous decade of hybrid work. You get developers who have shipped complex, production-grade apps, not developers who learned cross-platform as a secondary skill.
Store Compliance Ownership
We handle App Store Connect submissions, Google Play release tracks, binary review correspondence, and privacy manifest requirements, particularly the App Privacy Report obligations introduced in iOS 17. Our team knows how to navigate review rejections without stalling your launch timeline.
Fast, Structured Onboarding
Most engagements reach active development within 3-5 days. We align on your Git workflow, branching strategy, CI/CD tooling, and task management setup before writing a line of code. No two-week discovery periods before anything gets built.

Industries Covered
Flutter and React Native apps built for iOS and Android from a shared codebase, with platform channel integrations for native device APIs, biometrics, and camera access.
.svg&w=96&q=75){kind=small}
Mobile tools for internal teams, field service apps, approval workflows, and operations dashboards with Active Directory authentication, MDM compatibility, and offline data sync.
On-device ML inference using TensorFlow Lite or Core ML bridges within Flutter or React Native apps, covering image recognition, NLP features, and AI-assisted user flows.
Migration of legacy Xamarin, Cordova, or Ionic codebases to Flutter or React Native, retaining business logic while resolving performance bottlenecks and deprecated dependency chains.
Companion apps for Wear OS and watchOS built alongside the main cross platform product, sharing health data APIs, push notifications, and Bluetooth peripheral sessions.
Augmented reality experiences built with ARCore and ARKit through platform channels in Flutter or React Native, used in retail, field inspection, and training applications.
Mobile interfaces for IoT hardware using MQTT, BLE, and WebSocket protocols built to handle device pairing, telemetry display, and edge-to-cloud data pipelines.
Payment gateways (Stripe, Razorpay), analytics (Mixpanel, Amplitude), CRM connectors, and push notification infrastructure using FCM and APNs across both platforms.
Rebuild of existing single-platform iOS or Android apps into cross platform codebases using Flutter or React Native, with zero feature regression and full regression test coverage.
Need a Developer Fully Committed to Your Product?
A dedicated Flutter or React Native developer works exclusively on your codebase, fully embedded in your sprints, your tools, and your release cycles, with no split attention across other projects.
Full Codebase Ownership
A dedicated Flutter or React Native developer owns your entire mobile codebase on both platforms, every sprint, every release cycle without splitting attention across other projects.
Sprint Integration
Your developer joins daily standups, participates in backlog grooming, and ships within your existing delivery rhythm without requiring a separate process or project layer.
Platform Continuity
The same developer stays aligned with your architecture decisions, state management patterns, and store compliance requirements across every development cycle.
Release Management
App Store Connect submissions, Google Play release tracks, and CI/CD pipeline ownership are handled directly, not delegated back to your internal team.
Industries We Build Cross Platform Products For
Cross platform development carries different technical and compliance implications depending on your industry.

Built for Every Stage of Your Business
The right cross-platform engagement looks different depending on where your product and team currently stand. Here is how we work across every stage.
Startups
Ship to iOS and Android from a single Flutter or React Native codebase without splitting your budget across two native builds or two separate engineering tracks.
Mid-Size Businesses
Keep iOS and Android in lockstep as your product scales. One codebase means one PR ships to both platforms, with maintenance costs running 40 yo 60% lower than parallel native builds.
Enterprise Level Businesses
Standardise mobile architecture across business units with shared component libraries, unified CI/CD pipelines, and consistent App Store and Play Store compliance across every product.
