Karen A.

Senior .NET developer with 20,000+ hours on Upwork and 100+ successfully completed projects — consistently delivering high-quality, maintainable solutions on time. I build robust ASP.NET Core web applications and APIs, and I integrate AI tools natively into my development workflow: using Claude Code and Cursor for faster, smarter coding, Perplexity for technical research, and ChatGPT for rapid prototyping. This means you get the output of a senior developer with the speed of a modern AI-assisted pipeline. Whether you need a complex MVC application, a clean REST API, or a Sitefinity CMS build — I bring both deep expertise and cutting-edge tooling to every project.
