What I'm looking for

I am seeking a mid-level .NET/full-stack role where I can build scalable ASP.NET applications, improve test coverage and database performance, work within Agile/Kanban teams, and grow into senior engineering responsibilities.

I am a Full Stack .NET developer with professional experience since 2017, specializing in ASP.NET MVC and Web Forms and grounded in C# and VB.NET. I focus on building scalable, maintainable systems, implementing automated tests, and improving database performance through careful query optimization.

I have automated ETL and data migration pipelines with Python, Java, and PostgreSQL, which drove an 80% increase in system closure rate, and I routinely develop and execute NUnit and Selenium tests while managing releases with SVN. I am driven by problem solving, collaboration in Agile/Kanban teams, and continuous improvement.
