Student Developer · AI/ML & Data Analytics · JC1 at Hwa Chong Institution
SingaporeI am a JC1 student at Hwa Chong Institution and a student developer focused on applied AI, computer vision, full-stack software, and agentic systems. I enjoy taking ideas from concept to working prototype: understanding the problem, designing the system, building the implementation, testing it, and improving it based on feedback. Long term, I want to build practical AI systems that solve real problems and continue developing the engineering judgement needed to turn prototypes into reliable products.
