Jia Dian's Portfolio

Or you can call me JD for short 😄

A Software Engineer with close to 4 years of experience in Fullstack Web Development, I thrive on analysing and solving problems through clean, purposeful code. I bring a keen eye for design to everything I build and strive to create meaning in my work. Welcome to my portfolio site!

Equinix Internship

As a Software Engineer Intern at Equinix Asia Pacific I built automation tools and gained hands-on experience with Agile, DevOps, Linux, and diverse technology stacks. Three main projects: (1) Ansible modules in Python, (2) a command-line utility tool in Python, and (3) a service-probe application in Spring Boot.

IM2073 – Eshop Spring-React Web Application

The second project for IM2073. Originally tasked to build a web shop using Java Servlets and Tomcat; revamped to use Spring Boot as the backend and React as the frontend, with MySQL as the database.

SCDF × IBM Hackathon: Elderly Care Smart Solution

My first hackathon with a group of NTU friends. Problem statement: with more elderly people living alone in Singapore, there is high risk of undetected emergencies. Our solution uses a smartwatch IoT device with machine learning to detect fall risk and heart rate, plus a chatbot to call emergency responders.

IM4717: JY Movies – Web Application Design

A final-year elective project where my friend and I built a mock cinema booking website using HTML, CSS, JavaScript, and PHP with a MySQL backend. Features include browsing and searching movies, viewing showtimes, booking tickets with seat selection, and managing bookings.

Final Year Project: Machine Learning and Simulation of GPR Data

Final year project where I worked with Ground Penetrating Radars (GPRs) to collect and synthesise tree root scans using Generative Adversarial Networks (GANs). By augmenting the GPR scans, this project aims to address the lack of data used for tree health monitoring and insights. Through this project, I experienced the full journey of machine learning, from data collection and preprocessing to model training and reiteration. By implementing and comparing different GAN architectures (DCGAN, WGAN-GP, pix2pix), I learned the nuances of making these models work, from fine tuning parameters and learning rates to recognising signs of mode collapse.
