As a man playeth

De La Salle University

These are my final projects for the classes I took at DLSU

Operating System from scratch

• Built an OS from scratch in C and Assembly for Advanced Operating Systems and Networking class, wrote almost every line of C-code (with some GPT help) with blood on my eyes and QEMU crashing in the background
• Reference: Professor Raquel T. Marasigan (email) (linkedin)
• Designed for pedagogical teaching similar to xv6, implementing recommendations based on this paper
• Early screenshots of the operating system in action: welcome screen to the left, and desktop on the right. In the right, we can see an example of the editor being used with the words “Hello rootOS is FUN!!!” typed into the screen, and a window opened, demonstrating the multi-tasking abilities. If you noticed it on the right, there's also a tiny easter egg - a configurable crucifix ✝️ cursor in honor of Terry Davis.

Distributed serverless E‑commerce app

• Built for a class called Advanced Systems Design and Implementation, wrote it in JavaScript + NodeJS and deployed to AWS
• Reference: Professor Fernando Jabon Jr. (email)
