I specialize in making blazing fast backends utilizing NodeJS. I have, however, worked with many other languages and frameworks in the past, and I pick up on new technologies very quickly. I'm also very comfortable working with frontends, where I make snappy, responsive user interfaces.
Backend development - I primarily use ExpressJS to create lightweight backends for all sorts of web applications. I have worked on simple CRUD applications as well as the backends for complex, real time, REST-driven frontends.
Design & UX - While I specialize in programming, I also have a good eye for design. I design user interfaces which are clean, minimalist, and get to the point. When working with CSS, I use SASS to create code which is organized and reusable.
