Eradani Inc
Eradani works with clients to update old IBM-i systems with modern web frontends.
I worked to develop proof-of-concepts for their clients, building something that could be demoed, with just a couple weeks turn-around.
Examples include internal tracking tools for large distributors of kitchen supplies and automobile glass, which you've probably used if not heard of.
I worked on a React/Typescript frontend, coordinating with 2 other interns working on other parts of the same project.
We had to work quickly, pushing to Github and merging code often.
All code I did for Eradani is closed-source and owned by Eradani.
