About

I’m Daniel A. Portillo, an aspiring full-stack developer and Information Technology student with a strong foundation in building user-focused web applications. I’ve developed hands-on experience with ASP.NET Web Forms, C#, SQL Server, JavaScript, HTML, CSS, and Bootstrap, and I enjoy turning requirements into solutions that are reliable, maintainable, and easy to use.

Beyond academics, I bring 10 years of professional experience and a detail-oriented problem-solving mindset shaped by my military service. Working in roles that required documentation, compliance testing, and technical support, I’m comfortable learning new tools quickly, collaborating with teams, and troubleshooting issues methodically—I can contribute effectively in a software development environment while continuing to grow my engineering and development skills.
