Hello, I'm

Ho Jian Feng(Marcus)

Generative AI & Full-Stack Developer — Building intelligent, scalable systems.

About me

I'm a final-year Computer Science student at Nanyang Technological University, with a focus on AI, full-stack development, and building systems that scale. My coursework spans Data Structures & Algorithms, Machine Learning, NLP, and Software Engineering.

I've interned at TE Connectivity (Generative AI & Full-Stack) and the Home Team Science & Technology Agency (multi-modal AI), and I enjoy turning complex problems into clean, production-ready solutions—from agentic AI microservices to modern Angular UIs used by tens of thousands of users.
