Hi, I'm

HackXperience 2026

24–25 Jul 2026 · SIM, Singapore · Team of 4

GutGenug: a business dashboard you sign into with Google. Ask one AI agent, and it checks orders and stock with two helper agents before answering.

Go · React · TypeScript · Python · Redis · Azure AI Foundry

What I learned

  • Setting up Google sign-in myself, from creating the credentials to keeping them out of the code.
  • Building with AI: about 10 hours shaping the idea, then the rest of the day turning it into a working app.
  • In hackathons the idea matters most. Judges liked our design and build, but wanted a bolder idea.
  • Teamwork: listening to three other views and combining them into one solution.

About

I study Computer Science at the University of Wollongong in Singapore, majoring in Big Data, Cybersecurity and AI. I build things people pay for and use: a TikTok live-streaming tool with paid plans, a licensing system for Windows games, and bots that run my daily chores.
