Present

.NET Developer
Independent Development

.NET developer with 11 years of experience in web development, including 7 years specializing in .NET technologies, primarily ASP.NET MVC and .NET Framework. Experienced in building, maintaining, and supporting enterprise applications used across multiple business systems.

I focus on feature development, system integrations, and production support for complex enterprise environments. I have experience creating internal dashboards, administrative tools, and service endpoints, and I serve as a subject matter expert for business-critical applications. My work includes coordinating deployments, troubleshooting issues, and mentoring other developers in team standards and workflows.

Technologies I work with include C#, ASP.NET MVC & Core, SQL Server, ADO.NET, JavaScript, jQuery, Bootstrap, and AJAX. I have experience with Jenkins for CI/CD, IIS, and Agile/DevOps practices. In personal projects, I have explored ASP.NET Core, Web API, and EF Core to expand my skill set.

I’m seeking roles where I can continue to leverage my .NET expertise, support enterprise systems, and contribute to development teams that value reliable, maintainable software and deep knowledge of business applications.
