Experienced Software Engineer that has worked with both consumer and enterprise apps. 5+ years of professional engineering experience. My current interests are scalable app architectures and functional programming.

Although I'm currently focused on Android development, I also have experience developing across the entire stack. I have developed multiple projects with React as well as creating micro-services with Node.js and Elixir. I am familiar with a variety of persistence technologies: PostgreSQL, ElasticSearch, and Redis.
