"Hello World!"

I am Junjie Wu, currently a computer science and electrical engineering double major student at the University of New South Wales (UNSW) with a passion for building things and making things work. My academic and project work spans a variety of areas, from hardware electrical design, like working on electric vehicles, to audio systems, and blending software with hardware in low-level embedded systems, all the way to developing software projects, including this front-end website you're reading right now. I'd love to collaorate on new exciting ideas so feel free to reach out for a chat!

Guitar Power Amplifier

(September 2024 - December 2024)

A guitar power amplifier for loudspeakers that delivers clear, high-quality audio with optimal efficiency. It takes weak stereo signals from audio jacks or microphones, amplifies them, and preserves signal integrity while minimizing total harmonic distortion (THD). The design features a multi-stage cascaded approach with separate stages for signal gain and power output, offering precise control over both audio clarity and efficiency.

Skills: Power Electronics, Simulations, PCB Design, KiCad

Sunswift Racing: MPPT Project

(September 2023 - December 2024)

I worked on an electric vehicle that set a Guinness World Record and won the 2023 Bridgestone World Solar Challenge. As the project lead for the Energy Systems Department, I was in charge of the MPPT (Maximum Power Point Tracking) project.

Skills: Power Distribution, Renewable Energy, Altium, Team Leadership, Project Management

RankIt Website (Hackathon)

(March 24th - 26th 2025)

As a Hackathon project, I worked on the backend of RankIt website in a team of two (my teammate focused on the frontend). RankIt is a platform built for UNSW students to rank a variety of categories related to UNSW, including courses, food, restaurants, toilets, and more.

The backend is built using ExpressJS in the Node.js environment, utilizing JavaScript. Firebase serves as the NoSQL database for real-time data storage, and Supabase is used for image storage. The frontend was developed with React and TypeScript, utilizing Node.js for the development environment and build tools.

Skills: JavaScript, TypeScript, ExpressJS, Firebase, Supabase, NoSQL Database, RESTful API

Audio Equaliser in C++

(December 2024 - February 2025)

I built a 5-band audio equaliser using C++ STL (no external libraries). The equaliser reads in an audio file and allows users to apply various gains to 5 frequency bands (sub-bass, bass, midrange, upper midrange, treble). It can also process stereo audio, apply dynamic range compression, and save the result into an audio file.

Skills: C++, MATLAB, Digital Signal Processing, Real-Time Processing

Personal Portfolio

(December 2024 - January 2025)

You are looking at this right now!

This is a static website built with vanilla JavaScript, HTML, and CSS. It's my first frontend project, made to showcase all my other projects in one place and serve as my personal website. I plan to improve it in the future by adding a backend server, exploring other frameworks and APIs, and integrating a database.

Skills: HTML, CSS, JavaScript, Git, UI/UX, Responsive Design

Ambient Sound Monitor System

(May 2024 - August 2024)

This project is designed for users who may struggle to stay aware of their surroundings or frequently operate in noisy environments. It leverages advanced real-time processing to detect key sounds and deliver alerts through haptic and visual feedback, helping users stay aware in such environments.

Skills: C, FreeRTOS, Digital Signal Processing, Embedded Firmware
