High-performance apps built with Xamarin and .NET MAUI.

Native iOS and Android apps from a single C# codebase built for enterprises that need platform-specific performance without platform-specific teams. Xamarin and .NET MAUI apps for regulated industries, enterprise systems, and mission-critical workflows.

AI-powered Xamarin development

Faster builds. Smarter Xamarin applications.

We embed AI at every stage of the Xamarin development lifecycle from project scaffolding and automated code review to performance profiling and App Store compliance checks so your enterprise mobile app ships faster and stays production-ready.

  • AI-assisted Xamarin project scaffolding

    MVVM architecture, shared code layers, platform-specific renderers, and dependency injection containers generated from your app spec reducing boilerplate and enforcing Xamarin best practices from the first commit.

  • Intelligent code review & .NET mobile standards

    Automated PR analysis catches memory leaks, main-thread violations, platform API misuse, and accessibility failures before they reach your QA team or App Store review.

  • AI-powered UI generation & design consistency

    XAML UI components and platform-specific styles generated from design specs maintaining design system consistency across iOS and Android without duplicate effort.

  • Performance profiling & battery optimisation

    Memory allocation spikes, UI thread blocking, and battery drain patterns surfaced continuously not discovered during App Store review or user complaints.

  • Smart test generation & device coverage analysis

    NUnit and Xamarin.UITest suites auto-scaffolded from screen and workflow specs, with AI-suggested device coverage for maximum platform compatibility confidence.

  • App Store compliance & release automation

    Provisioning profiles, entitlements, App Store Connect metadata, and Play Store listing validation checked and maintained automatically throughout development.

Xamarin Development Process

Six sprints. Your Xamarin app live on both stores.

SPRINT 1 / Discovery

Requirements & Xamarin architecture

Platform matrix, shared code strategy, enterprise integration requirements, and API contracts confirmed before development starts. You leave with a validated architecture and a device compatibility matrix.

SPRINT 2–3 / Design

Design + Xamarin scaffolding

Figma mobile designs, platform-specific adaptations, and the Xamarin solution scaffolded with MVVM structure, test suites, and CI pipeline configured before the full build sprint begins.

SPRINT 3–6 / Build

Xamarin development, weekly demos

Friday demo, Friday invoice. TestFlight and internal track builds from sprint 3 so you can test the real app on real devices. Pause anytime.

SPRINT 6 / QA & Performance

Device testing + performance profiling

Xamarin.UITest suites across the device matrix, memory profiling, battery optimisation, and App Store compliance review completed before submission.

SPRINT 7 / Launch

App Store + Play Store submission

App Store Connect and Play Console submission, ASO optimisation, and App Center monitoring configured before launch. We stay on through your first rollout.

+ ONGOING

Operate or hand off

Stay with us under SLA for ongoing feature development and Xamarin maintenance, or take it home with full documentation and a 90-day warranty.

Industry expertise

We've shipped here. Many times over

Deep teams with industry context - not generalists googling compliance acronyms. Each industry below has 30+ shipped projects and a partner who knows the regulator.

Word of mouth

What clients tell their peers.

Real names, real companies, real numbers. Video on the left, written notes on the right - choose whichever feels more honest.
