Baremetal Self-Hosted Kubernetes Cluster

#homelab

I started this in late 2023 with a single Raspberry Pi because I wanted to learn how bare metal Kubernetes actually works. Two years later, I have two Intel Xeon workstations with 18TB of storage. I run my audiobooks, music, photo archive, file sync, and a bunch of personal tools on it. I've nuked and rebuilt this cluster more times than I can count.

ResultScrape

ResultScrape

Web Scraping, Flask API, React Frontend

#reactjs#flask

I found out a vulnerability in my college's ERP system. At the same time, students had to go through an arduous process to get results of previous semesters. I used ScraPy to exploit that vulnerability and scrape the results data. After that, I built an API for that data using Flask and a webapp using ReactJS, where any student can get their results easily.
