About Me

I am a final-year Software Engineering student at Singapore Institute of Technology (SIT), currently interning at PSA International. I'm passionate about creating innovative software solutions that make a real impact. My technical interests lie in AI/ML, test automation, mobile development, and full-stack web applications.

What motivates me is the opportunity to solve complex problems through technology. I love the challenge of translating real-world needs into elegant software solutions, whether it's developing AI-powered platforms or creating user-friendly mobile applications. Every project is a chance to learn, grow, and contribute something meaningful to the world.

My journey includes building end-to-end test automation for port operations systems at PSA International, developing inventory management systems at NEC Asia Pacific Pte Ltd, and active participation in hackathons and tech competitions. I've worked on projects ranging from RAG agents and AI-driven job matching platforms to fitness tracking applications, always focusing on creating solutions that are both technically sound and user-centric.
