About Me

Hi, I’m Jordan!

I am a third-year Computer Science undergraduate at Nanyang Technological University, specializing in Software Engineering and Cybersecurity. I am grateful to be a recipient of the Wee Cho Yaw Future Leaders Scholarship, which supports my full degree studies through to 2027.

Before NTU, I graduated from Ngee Ann Polytechnic with a Diploma in Information Technology (With Merit), achieving a near-perfect GPA of 3.98/4.00. I was recognized as the Second Most Outstanding Graduate, awarded the Singapore Computer Society Silver Medal & Ngee Ann Polytechnic Achievement Award and consistently placed on the Director’s List. My journey in tech began at the Institute of Technical Education, where I earned a perfect GPA of 4.00 in Web Applications and graduated with Merit.

Professionally, I am the Director of Marketing & Technology at Three Butlers Pte. Ltd., a company I actively built from ground-up since 2024. I lead the digital transformation, SEO, and workflow automation—growing our website to 1–2K monthly visitors and achieving first-page Google rankings within six months. I also execute digital marketing campaigns that have generated over 66,000 impressions and 1,200 monthly ad clicks.

Previously, I was a Service-Oriented Architecture Developer at OCBC Bank, where I was actively involved in the design, development and maintenance of middleware services that supports 10,000+ applications/systems deployed by the bank. My work in automation cut resolution times in half and ensured 95%+ uptime across critical banking systems.

I am deeply passionate about web and mobile app development, software design, and cybersecurity, with experience spanning Java, Python, C/C++, mobile development, SEO, and systems engineering. From leading hackathon-winning teams to delivering client websites, I thrive at the intersection of technology, design, and business impact.
