I'm a Embedded Systems Engineer who graduated from the University of Wisconsin: Platteville.
Outside my professional work, I spend my time reverse engineering and re-implementing different web services and APIs.
While most of my work is with embedded systems and web applications, I have experience developing for iOS, macOS, Linux, and more.
