Incoming NTU Math & Computer Science student, building useful software on the side.
A small machine learning library built from scratch in Python and NumPy with no PyTorch or TensorFlow. Built to actually understand how these machine learning models work under the hood: forward/backward passes, gradient descent, and loss functions written by hand.

I've written a small neural network library from scratch in Python, and made Android apps for productivity. Currently learning quantitative finance and competitive programming on the side and participating in CTFs. I enjoy running and cycling and hope to get into electronics and 3D printing.
