Projects

Distributed File System

Distributed Systems and Networks

This was created using Java, and was a distributed storage system with a controller and multiple nodes (DStores) to store the data. The different nodes communicated using sockets.

Quiplash Clone

Cloud Application Development

This was made using VueJS and Bootstrap, with an accompanying API being coded in Python. The frontend was hosted on Google App Engine, and the API was hosted on Azure Functions and Cosmos DB.

Tree CRDTs with Highly Available Move Operations

3^rd Year Project

This project contains the creation of a new Tree CRDT in Go, as well as the implementation of an already existing Tree CRDT. Then compares the performance between the two algorithms. It aims to leverage the benefits of CRDTs to create a system that is highly available and fault tolerant.

Model Rocket

Team Project

There is two of us working on this project, and we have already had 2 launches of a previous version of the rocket, which was controlled using MicroPython. We are now working on the next version of the rocket, which is being coded using C++. The rocket is 3D-printed and initially utilized a Pi Pico. The current version, however, features an upgraded Teensy 4.1.
