You’ve probably used products built by our .NET developers.
We've been providing .NET development services for leading brands since 2009. Our .NET developers create software that clears payments in milliseconds, protects clinical data, and serves millions of daily users. When performance and uptime are on the line, we’re who companies call.
We build enterprise-grade web platforms from the ground up—combining robust ASP.NET Core APIs with modern, responsive web front-ends. Our APIs run in containers and auto-scale on AWS or Azure, while our front-end teams deliver secure, user-friendly interfaces across devices. Together, these capabilities create complete platforms that are resilient, easy to integrate, and designed for both end-users and developers.
That old .NET monolith is costing you more than just server space. We tackle the hidden costs by migrating .NET Framework 4.x estates to .NET 8 without halting production. Our engineers incrementally port WCF and WebForms components, keeping your system online. You get a future-ready codebase, lighter infrastructure bills, and the freedom to adopt more efficient cloud services.
We deliver native-performance apps for iOS, Android, Windows, and macOS from a single .NET MAUI codebase. Many cross-platform frameworks fall short when you need enterprise-grade features like encrypted storage, biometric authentication, and offline sync—requirements that are standard in regulated industries such as healthcare and finance. With .NET MAUI, our specialists share business logic across platforms while tailoring the UI layer for each device, then automate store deployments through GitHub Actions. So your users enjoy consistent experiences while your team maintains one repository.
We provide a comprehensive quality strategy that goes beyond basic unit tests. Our QA specialists design and implement robust automated testing suites, including integration, performance, and security testing. We use industry-standard tools to identify bottlenecks and ensure your .NET applications are stable, performant, and ready for production launch.
We transform raw operational data into actionable insight using .NET workers orchestrated by Apache Spark, Azure Synapse, or AWS Glue. As data volumes grow, mid-market and enterprise teams alike need platforms that protect sensitive fields, adapt to changing schemas, and deliver dashboards in near real-time. Our data engineers wire structured ETL pipelines, versioned Data Contracts, and Blazor or React front-ends. That foundation gives decision makers reliable metrics while governance stays intact.
Trading desks, imaging suites, and industrial HMIs still rely on rich Windows clients. We craft WPF and WinUI applications using MVVM and GPU-accelerated rendering to meet those demands. These environments often require hardware integration, real-time data feeds, and multi-monitor layouts—capabilities we deliver in close collaboration with your product and security teams. Your staff gains intuitive tools that remain maintainable through future Windows releases.
Great .NET software deserves a great platform. We design and build the automated infrastructure your services need to run reliably on AWS or Azure. Using Infrastructure as Code (Terraform, Pulumi) and mature CI/CD practices, we create a stable, secure, and observable foundation for your applications, freeing your developers to focus on features, not plumbing.
Remote assets—from factory floors to field equipment—generate torrents of telemetry, often with unreliable connectivity. We build .NET IoT modules for ARM devices that buffer data locally, compress payloads, and sync securely to the cloud. To support real-world deployments, our teams also implement protocol gateways for MQTT, OPC UA, and Modbus, folding legacy sensors and machinery into modern analytics pipelines. This gives operations teams end-to-end visibility into assets while keeping bandwidth and power usage under control.

AP's legacy Classic ASP platform couldn't support modern omnichannel content delivery for its web, mobile, and social channels. We provided a team of senior engineers to migrate their entire content library, with over 3.6 million stories dating back to 1985, to a modern .NET framework. The new platform enabled dynamic, API-driven content delivery, improving the news experience for 1.5 million app users and 56 million social media followers.
To scale its market-leading learning management system (LMS), Blackboard needed to streamline development by integrating its core business systems. We provided a skilled development team to design and implement new processes, integrating key functions between their Salesforce and ServiceNow platforms. This systems integration streamlined support and development workflows, allowing them to innovate on their LMS more rapidly.
CropTrak needed to modernize its technology stack from legacy web forms to a modern MVC architecture to enhance its web and mobile products for the agriculture industry. We provided a dedicated team of senior .NET and Xamarin engineers who managed the full tech stack renewal.
