.NET development services

We've built on .NET since 2016. Enterprise backends, web applications, APIs, cloud infrastructure on Azure. C# is a core part of what we do, not an afterthought. We also push back when the brief needs it. That's usually how clients get more built for the same budget.

OUR SERVICES

.NET development that fits how you work

Finding developers who understand your business, not just the codebase, takes time you don’t have. Our .NET developers have built production systems across e-commerce, manufacturing, and healthcare. They join your team or own the project end-to-end. Either way, they’re productive from day one.

Custom .NET development

Web apps, mobile apps, cloud-native systems. We work with .NET 7+, Azure, AWS, and MS SQL Server. We’ve built everything from e-commerce platforms to product design tools with custom backend logic and third-party integrations.

API and integration development

We connect .NET applications with databases, CRMs, ERPs, and external services. ASP.NET Web API, WCF, REST. We’ve built secure access control systems handling product risk assessments and user permissions across enterprise environments.

Migration and modernization

Still on .NET Framework or Classic ASP? We migrate and modernize without breaking what works. Recent work includes upgrading legacy .NET 4.7.2 codebases to current Litium versions with Elasticsearch and microservices architecture.

BENEFITS

Why choose Zendev for .NET development?

Proven results

Proven results, not just expertise. We built a mobile application for Cargotec that improved operational efficiency by 103%. We increased revenue by 33% for Hidroxa and conversion rates by 445% for Magnetlabbet.

94% client satisfaction

Last year’s internal survey: 94% of clients reported a positive experience, while 65% of them were extremely satisfied and said they’d recommend us.

Cultural fit

Cultural alignment isn’t a soft benefit. It’s why our clients keep extending engagements. Our developers work the same hours as Western European teams, communicate directly, and take ownership without being managed.

Flexibility and scalability

Scope shifts. Requirements evolve. We adapt quickly whether that means scaling the team up, handling a legacy system mid-project, or changing direction entirely.
