What I'm looking for

I’m looking for an Agile team where I can build enterprise web systems end to end—RESTful APIs, React/SignalR features, and performance-tuned SQL—while deploying reliably on Azure and contributing to clean architecture and code quality.

I’m a Software Engineer with 4 years of experience designing, building, and maintaining enterprise-scale web applications using ASP.NET Core, ASP.NET MVC, C#, and Microsoft SQL Server.

I specialize in RESTful API development and clean architectural approaches, including Repository Pattern, Dependency Injection, SOLID principles, and Onion/Clean Architecture, with a focus on maintainable and testable codebases.

I build end-to-end features by integrating React.js frontends with backend services, and I’ve delivered real-time functionality using SignalR while supporting full-stack troubleshooting across production deployments.

I also strengthen performance and reliability by optimizing SQL queries, stored procedures, and CTEs, and by deploying to Microsoft Azure (App Services, Functions, Blob Storage) with Git-based collaboration in Agile/Scrum teams.
