ABOUT ME
I am a software engineer specializing in backend/full-stack work. I like building passion projects from scratch and learning new things to get my projects off the ground. Over five+ years of programming, I have picked up experience working with Java, Scala, JavaScript, Python and C/C++ on projects ranging from video games and music visualizers to deep neural networks and distributed key-value stores.
