Kudu Market

A live student marketplace for the University of the Witwatersrand. I designed and built it as part of a group project.

React + TypeScript on Cloudflare's edge · Postgres with row-level security as the only authorization · realtime chat · CI tests on a Slurm cluster · free tiers only.

Tuning AI world models for the ASC finals

PROBLEM: ASC is an international student supercomputing competition. Our team had to get a cluster running and make real workloads run as fast as possible on it.
DID: Supported the team in setting up the cluster, and optimised two GPU-based world-model AI models to run as quickly as possible on two AMD GPUs.
RESULT: International finalist in Wuxi, China. [speed-up achieved]

AI parking-lot monitor

PROBLEM: Know whether the parking lot is full without walking out to check.
DID: YOLO11 car detection and the full Python pipeline, on a Raspberry Pi 4 with a webcam. Set up the on-site networking.
RESULT: Deployed on site during vacation work at the Innovation Centre.
