Infomundi

I'm CTO at Infomundi, where I code full-stack and perform syadmin activities. The back-end was built using Python, while the front-end was made with Bootstrap and Vanilla JS/CSS. I actively maintain the site and plan to make it open-source in a near future.

I write articles and publish CTF writeups on my personal website.
