About Fariha
ASP.NET Developer | ASP.NET Core | AI Integration
Dhaka, Bangladesh - 6:55 pm local time
Hello! I'm Fariha, a Full Stack .NET Software Engineer with 7+ years of experience building and maintaining enterprise-grade web applications. Throughout my career, I've helped organizations develop scalable ERP systems, modernize legacy applications, optimize SQL Server databases, build secure REST APIs, and resolve complex production issues.
My approach starts with understanding the business problem before writing code. I believe software should improve business operations not just deliver features. By understanding workflows, pain points, and long-term objectives, I create solutions that are practical, maintainable, and built for growth.

My technical expertise includes C#, ASP.NET Core, .NET Framework, MVC, Blazor, Web API, React, Next.js, JavaScript, jQuery, SQL Server, PostgreSQL, MySQL, Dapper, LINQ, SignalR, Docker, Kubernetes, Azure, AWS, Git, Azure DevOps, and modern AI-assisted development tools that improve productivity while maintaining engineering quality.
