Hi, I’m Tham You Wei, a Software EngineerI build reliable mobile infrastructure and practical developer tools.
I’m a Software Engineer focused on Mobile Native Infrastructure at Shopee, where I work on foundations and internal libraries to help product teams in Shopee ship faster and more reliably. I enjoy keeping up with software trends and turning useful ideas into practical systems. A big part of my work involves building internal tooling and automation that improves developer experience and increases delivery confidence. Specifically, I architect libraries and endpoints that bridge low-level native OS capabilities with React Native, ensuring high-level frameworks remain performant and deeply integrated. I also develop native iOS features built for massive scale and optimal performance, whilst adhering to industry-standard release cycle practices such as greyscale releasing and A/B testing. Outside of work, I experiment with agentic AI architecture, focusing on how tool-calling and autonomous frameworks can extend LLM capabilities. Whether it's mobile infra or AI agents, I’m driven by the challenge of turning complex ideas into practical, reliable systems!
Side-note: I admittedly finally only started on this portfolio recently just to play around with the pretext library recently developed by Cheng Lou. Huge shoutout to him for revolutionizing the way we build text-based interfaces!

My Pet Projects
Side builds, experiments, and things I ship for fun.Some personal projects I build for fun and learning.
RideRingerA native mobile app that allows users to set alarms and notifications when they reach their intended destinations on long Bus/MRT rides
Stock PredictionI used A2C to train a model to predict the stock price of a given stock. This project was a fun way to learn about reinforcement learning and stock market prediction.
Generating 3D objects on MapboxA project for me to learn agentic applications on geospatial solutions. I created an agentic AI workflow to generate 3D objects on a map.
