About Me

I like coding, optimising and learning. My main focus is on full-stack development with Next.js, but I'm also interested in AI and neural networks. In my free time I play tennis and hit the gym.

Learning Builds

Guided builds where I worked through unfamiliar ideas in code.

Sequentia: Part 1

Worked through character-level language modelling, comparing a count-based bigram model with a gradient-based neural approach.

bigrams · probability · gradient descent

ZdravkoGrad

Worked through a small autograd engine and neural network library to understand computation graphs and backpropagation.

Raycasting Engine

Followed a raycasting build to understand how 2D geometry, rays and projection can create a simple 3D scene.
