What I'm looking for

I'm seeking roles building scalable enterprise .NET applications with cloud/DevOps practices in collaborative Agile teams, opportunities to lead modules, optimize databases, and deliver cost-efficient solutions that improve uptime and workflows.

I am a Full Stack .NET developer with 3+ years building enterprise applications across web, desktop, and mobile, specializing in .NET Core, ASP.NET, C#, SQL Server and API design.

I built an in-house ERP using .NET Core 8, SQL Server, and WPF that eliminated third-party dependency and saved the organization 40% in annual licensing; I designed scalable APIs and advanced SQL procedures that unified access across web, mobile, desktop and RPA, reducing reliance on external tools by 60% and cutting manual errors by 25%.

I work with Azure, AWS S3 and DevOps pipelines to ensure reliable deployments and 99.9% uptime, and I enjoy collaborating in Agile teams to deliver cost-efficient, high-quality solutions.
