Who I Am

I'm a second-year Information Engineering & Media student at Nanyang Technological University (NTU), currently on exchange at NUS focusing on Innovation, Product Design & Software Engineering. I'm on track for First Class Honours, with academic interests spanning both technical engineering and the design side of media and product.

My work sits at the crossroads of AI systems and real-world impact — whether that's building computer vision pipelines for robotics, engineering data-driven marketing strategies, or designing assistive technology for people with disabilities.

Outside of tech, I lead media and partnerships for Indonesia Cultural Night and contribute to the EEE Club's design and communications. I believe the best solutions are built by people who understand both the system and the human on the other side of it.

Game Development
Horror Game Environment Design

Designed and prototyped an immersive 3D horror environment in Unity, with custom C# scripting for interactive elements. Players must search a derelict house for a key, avoid a hidden threat, and use objects like a lantern and gun to survive — built from scene composition and lighting to particle effects and player interaction logic.

Data Analytics / Business Strategy
Short-Term Rental Market Entry Analysis

A capstone analytics project (simulated client, Watershed Properties) evaluating short-term rental conversion potential across 244 properties. Built a linear regression model to predict occupancy from rent percentile, then used Excel Solver to optimize rent and identify 41 profitable properties worth $1.37M in year, and presented via an interactive Tableau dashboard.
