I'm a software and data engineer at Marketing Decisions on the Gold Coast. Most days I'm in Snowflake and Python, building the pipelines, models, AI tools and internal apps that turn customer data into something a marketing team can act on.

Before that I built websites for clients in Malaysia and Australia. I graduated from Griffith University in 2025 with a Bachelor of Computer Science with Distinction.

I work in English and Mandarin, and also speak Malay and Japanese.
