I’m a Senior .NET Developer with 4+ years of experience in Enterprise Application Development, Telecom Billing Systems, SQL Server Database Development, and Production Support. I build and enhance REST APIs and database-driven business applications that stay reliable in real-world operations.

In my current role, I develop and maintain enterprise telecom billing applications and backend services using C#, SQL Server, ADO.NET, LINQ, and .NET technologies. I work extensively with ASP.NET Core Web API, Entity Framework Core, and SQL Server Stored Procedures, Views, Functions, Triggers, and complex T-SQL queries to support billing, reporting, and transaction processing workflows.

I’m especially strong in performance and stability: I optimize database performance, tune queries, and investigate production issues through Root Cause Analysis. I also contribute across the SDLC—from requirement analysis to development, testing support, deployment, and maintenance—and I’ve delivered scalable solutions like an Employee Management System using JWT Authentication, Dependency Injection, Repository Pattern, and Swagger/OpenAPI documentation.
