I was one of the 50 selected students participating in the pilot run of the Swift Accelerator Programme, launched by Apple and the Infocomm Media Development Authority (IMDA). There, I learnt how to apply design thinking principles to develop iOS apps using UIKit and Swift.
Projects
CTF write-ups
I write about the CTF challenges I solve and publish them online. The write-ups are hosted on a GitHub Pages website that uses a custom Jekyll theme. I set up a GitHub Actions workflow to sync write-ups across the main & publishing branches of the GitHub repository.
GRACE iOS App (2021)
In the 3-day-long CODE_EXP hackathon, hosted by the Defence Science and Technology Agency (DSTA), my team created an app that employs Bluetooth technology to make contactless usage of lifts accessible for visually impaired people. We also produced a demo video and slide deck to present our creation.
Discord.py Bot (2021)
I developed a Discord bot for a school community server. The bot used the Discord.py API, and performed some image processing using the Python Image Library.
Portfolio website
I created this portfolio website using React.js and Next.js, with the goal of presenting relevant information in a clear and interesting way, with a focus on being responsive and accessible.
