Technical owner of the direct-message content moderation system at TikTok, where I built pipelines that moderate billions of messages a day globally. At Canva, I built recommendation and search ranking models. I've deployed LLM-powered and agentic workflows in production for high-concurrency, low-latency use cases. I've conducted hundreds of interviews and interviewed at top tech companies across Australia. So I understand the rubrics and what it takes to win. I'm also the author of two books on TensorFlow and NLP.
