About Me

Hey there! Zender here - a name that becomes my default because 'Nathan' seems to be as common as poorly named AWS services.

I'm a seasoned full-stack developer, well-versed in backend development and the creation of various mobile applications. Lately I have focused more on DevOps and security engineering and how to use those tools and practices to build secure platforms and solutions for businesses. But what drives me is leveraging these skills to create secure, innovative solutions for businesses, driven by the challenge of solving complex problems.
