Getting GitHub updates on Discord

Mon, 23 Mar 2026 00:00:00 +0000

I’ll be honest, I set this up because GitHub email notifications just weren’t cutting it. They’re delayed, easy to miss, and honestly a bit noisy.

Instead of over-engineering a solution (which I was very tempted to do), I went with the simplest possible approach:

Let GitHub send events directly to Discord using a webhook.

No backend. No scripts. Just HTTP.

Requirements

Before starting, make sure you have:

A GitHub account with a repository
A Discord server where you can create webhooks

How This Works

At a high level:

Building CatWiz: A Prompt Injection CTF Challenge

Introduction

As large language models become more integrated into real-world applications, prompt injection has emerged as a critical security concern. These attacks exploit how AI systems interpret input, often allowing users to bypass safeguards and extract sensitive information.

To explore this problem in a hands-on and engaging way, my teammate Hiten Gupta and I partnered with the AIML Club - Adelaide University to design and host Catwiz, a Capture The Flag (CTF) challenge centered around AI prompt injection.

My Insane Blog Pipeline

Tue, 24 Feb 2026 00:00:00 +0000

I’ve reached a point where my brain is essentially a browser with too many tabs open. To fix this, I decided to start blogging for two reasons: I needed a “second brain” to offload everything I’m learning, and I stumbled upon a NetworkChuck video that made building a blog pipeline look like the perfect sandbox for some DevOps experimentation.

Instead of just “making a website” I decided to treat this like a real engineering project. I’ve been procrastinating on my portfolio for years, so I figured I’d finally build it properly using CI/CD, GitHub Actions, and modern static site practices.

Minesweeper 2.0

Sat, 07 Feb 2026 00:00:00 +0000

Reinventing a Classic: Building Minesweeper 2.0

Introduction

Few games are as iconic and deceptively simple as Minesweeper. Beneath its minimal interface lies a game of logic, probability, and careful decision-making. However, while the original game is timeless, it leaves little room for variation or innovation.

That’s exactly the challenge Minesweeper 2.0 set out to solve.

The goal of this project was to reimagine the traditional Minesweeper experience by introducing powerups, while preserving the core logic-driven mechanics that make the game so engaging. Built using C++ and the SFML graphics library, the project focuses on delivering a smooth, responsive, and visually intuitive desktop gaming experience.

SmartCourse Advisor: Merging AI, Data, and Student Voices

Introduction

Choosing the right university courses is a decision that can significantly shape a student’s academic journey, yet the process is often fragmented and overwhelming. Students typically rely on scattered sources such as informal reviews, outdated course guides, or trial-and-error when planning their degree.

This challenge becomes even more relevant in the context of institutional change, such as the University of Adelaide merger, where navigating course options can become even more complex.

Cinematch

Building Cinematch: A Full-Stack Movie Discovery Platform

Introduction

One of the biggest problems with modern streaming platforms is not the lack of content, it’s deciding what to watch. With thousands of movies and TV shows available, users often spend more time browsing than actually watching.

To solve this, We worked on Cinematch, a full-stack web application designed to make movie and TV discovery fast, personalised, and interactive. The goal was to create a platform that feels engaging like a swipe-based app, while still providing powerful filtering, search, and watchlist management features.

Spotify Analysis

Exploring Music Through Data: Spotify Audio Feature Analysis

Introduction

Music is often described as emotional and subjective, but beneath that subjectivity lies a rich layer of measurable data. Platforms like Spotify analyze tracks using detailed audio features such as danceability, energy, and valence, offering a unique opportunity to study music from a data-driven perspective.

This project, Spotify Audio Feature Analysis, was designed to explore how these characteristics vary across genres, popularity levels, and time. By combining publicly available datasets from Kaggle with additional metadata retrieved via the Spotify Web API, the goal was to uncover patterns in how music evolves and what defines different styles of sound.

Typing Speed V2

Sat, 07 Jan 2023 00:00:00 +0000

Building a Fast, Minimal Typing Speed Test with Python and MySQL

Introduction

Typing speed tests are a simple but effective way to improve accuracy, speed, and consistency while working on a computer. Most online typing platforms rely heavily on graphical interfaces and web-based systems, but I wanted to explore a different challenge: building a fast, responsive, and fully terminal-based typing experience powered by a real backend database.

That idea led to the development of Typing-Speed-TUI-V2, a Python-based typing speed application featuring a Text User Interface (TUI) and persistent MySQL storage. The project was designed to combine low-level terminal interaction with backend engineering concepts such as authentication, database management, statistics tracking, and secure password handling.
