About Me

Hi, I’m Pung Kah Jyun, a dedicated technology professional with a strong foundation in problem-solving. I’ve graduated in Information Systems at the National University of Singapore in August 2025, where I’ve developed proficiency in Java, Python, and other key technical skills. My academic achievements include a Business Management diploma from Nanyang Polytechnic, with a CGPA of 3.78/4.

At present, I’m working as a Software Engineer at Port Singapore of Authority, where I’m enhancing my expertise in Software Engineering. My work involves using Java, C#, Node.js, and more. Previously, I interned at CPF and GXS Bank, where I was given the chance to research + develop + create Gen AI applications in designing and implementing systems such as multi agents system, before GPT creates their own agents (man I have to find new things to do)...

My initial tech experience came from an internship at Trinax Private Limited, where I worked as a Software Developer and Tester. I contributed to software design and development and conducted extensive testing, reinforcing my dedication to quality and effective teamwork.

Feel free to check out my LinkedIn profile or portfolio website to see some of the projects I’ve worked on. Let’s connect and discuss how I can contribute to your team’s success.
