Xamarin Development Outsourcing Company in USA
Siblings Software is a Miami-headquartered Xamarin engineering services provider that approaches mobile platforms as evolving ecosystems, not discrete project deliveries. Our integrated engineering units combine .NET enterprise architects with user research specialists, inclusive design practitioners, and production deployment engineers ensuring every target platform—from iOS devices to industrial Windows tablets—delivers native-feeling performance and operational reliability.
Organizations partner with us when development throughput declines or internal engineering teams require reinforcement during transitions from legacy Xamarin.Forms implementations to contemporary .NET MAUI architectures. We integrate alongside your product leadership, streamline complex deployment workflows, and transfer proven methodologies developed across healthcare systems, supply chain platforms, financial technology solutions, and mobile workforce applications.
- Dedicated pods aligned to U.S. Eastern and Central time zones with fluent English and Spanish collaboration.
- Reusable UI libraries, device lab testing, and telemetry templates that shorten release cycles by 30% on average.
- Compliance-first delivery for HIPAA, SOC 2, and PCI projects with documented threat modeling and audit-ready artifacts.
Xamarin Engineering Service Portfolio
Multi-platform applications delivering native-level user experiences, enabled by systematic delivery methodologies.
Our Xamarin engineering practice is guided by system architects who launched their initial mobile applications during Xamarin's Mono project origins. Currently we employ the same proven methodology: participatory planning sessions, product telemetry integration from the first development cycle, and incremental release cadences supported by physical device testing infrastructure and deployment safety mechanisms.
Product Engineering
for iOS, Android & Windows
We craft design-led mobile products with Xamarin.Forms and .NET MAUI, extending them with native renderers or bindings when performance matters. Expect biometrics, offline sync, device permissions, and enterprise-grade security baked in—not bolted on at the end.
Platform Modernization
and Legacy Rescue
Have an older Xamarin app that needs a path to .NET MAUI? We audit architecture decisions, create migration branches, and refactor brittle renderers while keeping production support steady. Technical debt gets paid down alongside new features.
API & Cloud Integration
with Azure & AWS
Our engineers align mobile front ends with secure microservices, event-driven backends, and analytics pipelines. We build REST and gRPC gateways, integrate Azure AD B2C or Okta, and instrument telemetry with Azure Monitor, App Center, and Elastic so product teams can react to real data.
Need a different engagement? We also provide UX audits, automated UI testing with Appium, and mobile DevOps coaching to help your internal team succeed long-term.
Our systematic Xamarin evolution methodology
Each partnership follows a clear execution framework ensuring stakeholders understand upcoming activities. We collaboratively develop technology roadmaps, leverage analytics to sequence enhancement initiatives, and utilize established tools from the .NET MAUI platform ecosystem and the .NET migration automation toolkit.
Discovery & assessment
- Architecture heat map covering renderers, custom controls, and third-party SDKs.
- Product discovery workshop to rank user journeys and success metrics.
- Security and compliance scan aligned with OWASP MASVS.
Build & release
- Dual-track agile delivery with backlog refinement and weekly show-and-tell demos.
- Automated testing matrix that spans unit, snapshot, and device-lab smoke suites.
- Release trains orchestrated through Azure DevOps, GitHub Actions, or Bitrise.
Measure & evolve
- Telemetry dashboards in App Center and Grafana monitoring adoption, retention, and crash-free sessions.
- Monthly roadmap reviews grounded in user research and product analytics.
- Knowledge transfer, playbooks, and pairing sessions to empower your in-house team.
Need stakeholder buy-in? We share anonymized scorecards and measurable outcomes from similar projects so your leadership can see how modernization pays off.

Do you want to outsource Xamarin development?
If you need a consulting partner who understands regulated industries, field operations, or consumer mobile, we will help you design, build, and continually evolve your Xamarin product without sacrificing velocity.
Custom Xamarin Software Development
Every engagement starts with a product discovery sprint. We map personas, prioritize features, and define KPIs to ensure that the Xamarin solution we build moves the needle for your business. Our architects evaluate whether to stay on Xamarin.Forms, adopt Microsoft’s latest guidance, or hybridize with native Swift/Kotlin components for advanced device interaction.
What we typically deliver
- Design systems and reusable UI libraries aligned with your brand.
- Modular architectures (MVVM, Clean Architecture, Prism) with dependency injection.
- Secure integrations with ERPs, telematics platforms, or IoT devices.
- Automated build pipelines (Azure DevOps, GitHub Actions, Bitrise) with staged rollouts.
How we keep quality high
- Test pyramids mixing unit, snapshot, and device lab testing.
- Real-time analytics dashboards and crash monitoring.
- Continuous accessibility reviews and localization support.
- Comprehensive documentation and knowledge transfer workshops.
Case Study: FleetPulse Technician App
A U.S. fleet management company needed to replace three disconnected mobile apps with one experience for over 1,200 field technicians. We delivered a Xamarin.Forms application backed by Azure Functions that ingests telematics data and syncs work orders offline. Our discovery sprint surfaced key gaps in connectivity, so offline-first architecture became a priority from the start.
- 74% reduction in time-to-complete inspections thanks to barcode scanning, diagnostics integrations, and on-device caching.
- Real-time dashboards built with SignalR, surfacing truck availability to dispatch teams and reducing wait time by 32%.
- Single codebase deployed to iOS, Android, and ruggedized Windows tablets with device-specific renderers stitched together through Xamarin platform specifics.
- Zero-sev-one incidents across the first six months of production thanks to automated regression suites and staged rollouts.
“Siblings Software collapsed three legacy apps into one without slowing our crews. The team was honest about trade-offs, handled compliance with ease, and left us with playbooks we now use on every rollout.” — Director of Field Technology, FleetPulse
After launch we trained the client's internal developers, documented deployment playbooks, and transitioned to a shared support squad for ongoing feature releases and analytics experiments.
