Custom Software Development

Dotnet Turkey develops business applications where software has to fit into an established operating model rather than start from a blank page. Typical work includes internal enterprise platforms, customer portals, mobile applications, backend services and system extensions. Architecture decisions are made with existing data models, identity systems, integration points, operational ownership and support processes in view.

For .NET environments, we work with current C# and .NET releases, including .NET 8, and combine these services with Angular, React or React Native frontends. REST APIs, asynchronous messaging and event-driven patterns are used where they fit the process. The goal is not to introduce complexity for its own sake, but to establish boundaries that are understandable and testable.

Existing systems often contain years of business logic that cannot be discarded. We assess which parts should remain, which interfaces should be isolated and which components should be replaced. Modernization can therefore range from a runtime upgrade and modular refactoring to extracting services from a monolith, introducing API layers or rebuilding selected user interfaces.

Where a legacy system continues to perform its core function, we can place modern services around it instead of forcing a full rewrite. This reduces migration risk and allows business teams to validate new functionality in stages. Release planning, data migration and rollback paths are treated as engineering topics from the beginning.

Projects are suitable for private companies, industrial organizations, financial institutions, public-sector environments and technology businesses. Depending on the project, the team can cover business analysis, software architecture, implementation, testing, DevOps and technical handover. Code review, automated testing and deployment controls are integrated into the development process rather than added after implementation.
