Building the next generation of web and mobile experiences.

About

Hi! I'm Nick Tietje. I'm an incoming computer science Master's student at Northeastern University. I'm currently employed as a Software Engineering Intern at Fidelity Investments.

I love creating practical tools and sharing them with the world. In my free time, I've released a mobile app for tracking Magic: The Gathering games, which has over 3000 installs. I've also contributed to open-source projects like RMG-Py, a computational modeling software used and developed by researchers at MIT and Northeastern University.

Beyond coding, I'm an avid board gamer, reader (sci-fi and fantasy), cyclist, and amateur chef, always seeking new challenges and experiences.
