Professional Bio

I always liked to create things, so when I realized that I could create with nothing more than a computer, I was sure that I wanted to work as a software developer. When I’m developing for IoT devices or residential automation, I prefer using Python, but when I creating websites or mobile apps, my favorite technology is React. I'm self-taught, competitive, and determined, and when I'm not working, I enjoy playing soccer and video games.
