Drawing on our 20 years of experience with .NET application development, we can confidently help you decide if .NET platform is the most optimal option for your objectives, create a full-fledged development strategy, and help you realize the full value of one of the most matured developer platforms. 

Microservice architecture design

Our microservice designs address the scalability pain points head-on, employing .NET to craft architectures that evolve along with your business needs. With this approach, applications become more resilient and scalable while .NET development cycles are speeding up. 

API development and integration

Our .NET software development company specializes in designing and implementing custom APIs that let your .NET solutions and external systems transmit data in the most efficient way possible. We use Azure Service Bus, SignalR, or gRPC for integrations and ASP.NET Core to build restful APIs, and GraphQL for custom data fetching. Equipped with strict access control rules, latest security protocols, and detailed documentation, integration initiatives turn from challenges into opportunities. 

Migration and upgrade

Alongside offering track-proven engineering excellence in tackling complex migration challenges, we also support your migration initiatives with a tailored project management system. Whether it’s migrating from a legacy solution or upgrading the existing .NET application to the latest version, we ensure that your core infrastructure remains operational during updates and is ready for the technological challenges of the future. 

Quality assurance for .NET applications

Our rigorous QA processes, integrated within CI/CD pipelines, guarantee that your .NET applications meet the highest standards of quality. From unit tests to compatibility ones, we run a suite of comprehensive checks to address the critical demand for flawless, user-centric applications.

Maintenance & support

Most .NET development initiatives are not one-and-done engineering endeavors, but continuous projects that require proactive support and upkeep. Our .NET engineers will routinely optimize performance, manage compliance, and monitor security to keep your app running at peak efficiency. 

Multi-platform UI development

Leveraging .NET MAUI, Xamarin, and Blazor Hybrid, we create UIs that shine bright across all platforms. Our approach to UI development requires much less development resources due to MAUI’s unified codebase feature and addresses the critical need for responsive designs that foster the emotional connection between the user and the app. 

.NET app containerization

By containerizing .NET applications, we isolate applications from each other, increasing their efficiency and scalability. This deployment strategy ensures your applications are resilient, easily manageable, and cloud-ready.
