Hello! My name is Matti Jokitulppo and I'm a programmer currently stationed in Espoo, Finland. I'm currently getting my Master's degree in Computer Science at Aalto University and working at Reaktor as a developer. This is my website! Anyways, here's my resume, and down there you can look at some of the projects I've made, view the source code and all that good stuff. If you'd like to see more, take a look at my GitHub profile.
