// about me

Get to know me

I'm a Software Development Engineer II at Amazon, building and operating business-critical distributed systems for automated grocery fulfillment. I helped build the software foundation for the initial two-site pilot and now work on platforms supporting rapid network expansion.

I also developed an internal AI engineering platform adopted by 35 users across three teams. Alongside full-time work, I'm completing a Graduate Certificate in Computer Science focused on artificial intelligence and machine learning at the University of Queensland.

I started paid freelance development in 2017, delivering more than 60 Java plugin projects for 22 clients. My open-source Minecraft plugins have more than 30,000 downloads and attracted contributions from other developers.

I organized and hosted 5 music festival events to raise money for charity. The most recent event in July 2024 was a 2-day festival that raised A$1,500 for the TopBlokes Foundation, a charity dedicated to providing mental health support programs to young adults.

Across all 5 events, a total of A$6,500 (approximately US$4,500) was raised for charity.
