I’m Raihan Nishat, a Software Engineer specializing in ASP.NET Core, Clean Architecture, and enterprise-grade backend development. I enjoy building scalable, maintainable, and configuration-driven systems that solve real business problems through clean code and strong engineering practices.
Throughout my journey, I’ve worked on legacy system modernization, dynamic business logic implementation, architectural improvements, and background services that enhance performance and system reliability. I focus on clean abstractions, runtime polymorphism, modular design, and writing code that remains easy to evolve as requirements change.
- Build and optimize backend systems using C#, ASP.NET Core, EF Core, Dependency Injection
- Refactor codebases following SOLID, DRY, and Clean Architecture
- Implement CQRS, Repository & Unit of Work, and mediator-based designs
- Write reliable unit tests using xUnit, NUnit, Moq, FluentAssertions
- Develop background jobs using HangFire and Worker Services
