Hi A common challenge in enterprise .NET systems is maintaining performance, code quality, and scalability as APIs and business logic grow over time. I work as a senior .NET engineer designing clean architectures with C#, ASP.NET Core, and RESTful Web APIs that remain easy to extend and test. I have strong hands-on experience with Entity Framework and Dapper, choosing the right data-access strategy to balance maintainability and performance on SQL Server. I focus on writing optimized, well-documented code and applying best practices such as dependency injection, SOLID principles, and proper exception handling. On the frontend side, I collaborate comfortably with Angular, React, or Vue teams to ensure API contracts are clean and predictable. I’m experienced with Git-based workflows and Agile environments, contributing actively to technical discussions and architectural decisions. When needed, I also support Azure deployments, CI/CD pipelines, and Dockerized services to keep delivery reliable. Thanks, Hercules
