About
I build technology that helps people do more with confidence.
I'm Yong Jun, a software engineer focused on turning complex problems, evolving requirements and ambitious ideas into reliable software. I'm constantly looking for opportunities to both hone my craft and create better products.

Background

Whether as a student or a professional, curiosity has always been the driving force behind how I learn, build and grow.
Before university, I taught myself Swift in a week to build a Swift Playground for Apple's WWDC Scholarship. During National Service as a Cyber Specialist, I developed automation tools that reduced manual processing time by up to 90%, while gaining hands-on experience defending enterprise systems in a Security Operations Center. That experience inspired me to explore offensive security independently, leading me to earn the OSCP certification and participate in capture-the-flag competitions.
At SUTD, I've continued growing as a software engineer through academic projects and leadership roles in ROOTech and the Digital Design & Development Club (3DC). Whether building software for coursework or creating solutions for the student community, I've enjoyed collaborating with others to turn ideas into products that make a difference. Through ROOTech, I've also had the opportunity to mentor fellow students, an experience that's shaped how I approach collaboration and continuous learning. Together, these experiences have reinforced my belief that the best technology solves real problems while remaining reliable, secure and easy to use.
How I Work
I enjoy working on problems where the solution isn't immediately obvious.
Whether I'm building a full-stack application, automating security workflows or experimenting with AI, I start by understanding the problem before thinking about the technology. I value writing software that's maintainable, designing systems that are resilient and building products that people genuinely enjoy using.
I believe the best products are built through thoughtful collaboration, strong engineering fundamentals and a curiosity to keep learning.
Focus
Today, my interests sit at the intersection of software engineering, cybersecurity and AI.
I'm particularly interested in building secure-by-design applications and agentic systems that reduce repetitive work while improving reliability. AI especially fascinates me in its potential to augment cybersecurity, from streamlining investigations to improving detection and response.
