My name is Andrea, and I am working every day to command every aspect of modern computers. I started learning scripting languages in my hometown in Nauvoo, IL at the age of nine on the whiteboard with a longtime family friend before eventually finding myself cutting my teeth on interesting contracts in the D.C. and Baltimore areas. I hope to one day be able to call myself a "full-stack developer" as I get closer and closer to understanding the circuits that make up modern computer systems. Currently, I understand most things down to the OS/embedded firmware level, but I am starting to dip my toes in the digital logic/FPGA pool.
