Welcome to my site! I'm Jonah Fleishhacker, a CS student at the University of Chicago. I love computer science, music, outdoor exploration, astronomy, ecology, and sharing those passions with others.
Portfolio
In 2020, I built an interactive synthesizer and sequencer using Elm. It features many scales, separate keyboard/sequencer input, saving and loading files, and customizable BPM, length, and synth types. I really enjoyed making this, and still often play around with it for fun! Check it out above.
During the summer of 2020, I interned for the Bohdan Khomtchouk lab at UChicago, where I designed an application to visualize force-directed networks in augmented reality on mobile devices. Here is an early demo from the project.
During the summer of 2021, I interned for Mobius Materials, where I did full stack development (React/Django/Postgres). Responsibilities included helping create the silicon shortage tracker, migrating authentication services from Keycloak to Auth0, and implementing server-side rendering for SEO.
In 2021, I also created Covid-Twitter-Bot, a program that collects data from HHS/NYT, filters/cleans it, and posts various visualizations to my twitter page. Code, documentation and examples can be found in the linked repository. I used Python, specifically Pandas for data wrangling and Matplotlib for visualizations. The program is deployed on a heroku server with a daily schedule to fetch the data, generate the images, and post a Twitter thread.
About Me
I am a 4th year student at the University of Chicago, studying computer science and public health. In my free time, I enjoy exploring the outdoors, playing/listening to music, learning about natural sciences, and toying with data. Here's a photo of me at the Colorado national monument. Stopped by here on my drive back to SF after spring classes were moved online.
