12+ Years of App Development
Everything from a single source
50+ Successful App Projects
We build and modernize business-critical apps with .NET MAUI - new cross-platform products, Xamarin migrations, and long-term support. You get predictable delivery, a stable codebase, and clear ownership.
.NET MAUI is the smart way to reach as many people as possible on as many devices as possible with just one app.
Consistent UX is table stakes. We add automated testing, code reviews, and release discipline to keep quality stable across platforms.
A single codebase reduces duplicated work—while our architecture choices and documentation reduce vendor lock-in and maintenance risk.
We align scope, milestones, and acceptance criteria early—so you can plan budgets and internal rollouts with confidence.
We stay accountable post-launch: monitoring, updates, roadmap iterations, and team continuity—so your app keeps delivering value.
Cayas has specialized in mobile app development for over twelve years, with extensive experience in .NET MAUI and Xamarin. As a certified Microsoft partner, we know exactly what's important in cross-platform development.
We develop excellent cross-platform apps based on .NET MAUI, primarily for B2B companies in various industries. These include custom solutions for logistics, agriculture, and building security.
Our developer team creates both simple and complex applications for small and large companies that work equally well on smartphones, tablets, and desktop devices. For you, this means maximum reach with efficient development.

How We Work
We guide you as a dedicated partner at eye level—from the idea to the finished app. With passion, experience, and a holistic view, we turn smart ideas into professional digital solutions. As an officially recognized .NET MAUI specialist, we bring not only expertise but also genuine interest and passion to every project.
.NET Multi-Platform App UI—or .NET MAUI for short—is an app technology from Microsoft that allows a single app to be created for multiple platforms at once, without duplicating effort. It enables the development of an app for Android, iOS, Windows, and macOS without having to write separate code for each platform.
By the way: .NET MAUI is the successor to Xamarin. If you want to learn more about Xamarin or already have an existing Xamarin app, you can find more information here:
FAQ
We scope the work in a short discovery (goals, users, platforms, integrations, security, success criteria). You receive:
We typically use either milestone-based fixed scope or a monthly team package:
In both cases you get cost transparency and a clear change-control process.
You own the deliverables: source code, repositories, and documentation. We set up access from day one and align IP/licensing clauses with your procurement requirements.
You get a staffed team and documented architecture instead of a single point of failure. We use quality gates (code reviews, CI/CD, testing), clear ownership, and project governance so delivery does not depend on one person’s availability.
Yes. We offer post-launch support, monitoring, bug-fixing SLAs, and planned feature iterations. If you prefer, we enable an orderly handover to your in-house team with documentation and knowledge transfer.
Yes. We assess your Xamarin codebase, dependencies, and UI approach and propose an incremental or full migration. The goal is continuity: keep business functionality stable while modernizing the stack and improving maintainability.
After the initial call, we typically deliver a feasibility outline within days. As a guide:
Start dates depend on scope and availability, but you will always get realistic milestones.
Yes. We build GDPR-compliant by default and can align with additional requirements (e.g., SOC 2 evidence, HIPAA considerations) depending on hosting, data flows, and vendor policies. Security and privacy are addressed early and validated during delivery.
