Lefinno Kwok
Developer & CreatorI'm a developer with a wide range of interests spanning embedded systems, computer vision, game development, and web applications. I enjoy the challenge of taking an idea from concept to completion, whether that means designing a PCB, training a model, or shipping a web app.
My projects reflect my curiosity — from building an 8-bit transistor computer from scratch, to developing gesture recognition systems, to creating tools that leverage large language models for diagram generation.
