AI agents and full-stack web apps: LLM tool loops, APIs, and deployed front ends.
01Next.js / Flask / Full-stack
A full-stack feedback board: people submit ideas, upvote, comment, and follow each one on a roadmap. Built from a Frontend Mentor design.
02AI agent / Python / LLM
An LLM travel agent that drafts an itinerary, then revises it in a ReAct think–act–observe loop with weather and activity tools.
03Robotics / Voice AI
A voice-driven C-3PO head that wakes when you step close, with three modes: daily conversation, language translation, and Star Wars talk. The video covers its design rationale and how it compares with other robots.

How the game was designed: market research, story and moodboard, concept sketches, storyboard, mechanics, level design, and VR interactions.
Creation
Story channels where AI handles writing, visuals, voice, and video drafts — and my own design and editing judgment shapes the result.
All channels
AI-made anime shorts about everyday life
Short sci-fi narratives about future worlds
About
Design, programming, and new technology have pulled at me since my bachelor’s degree, so I’m studying both sides properly — interaction design at Monash, and now computer science with a focus on AI and HCI at the University of Sydney.
I learn by making: interviewing people, prototyping fast, testing, and refining until an idea holds up. Lately that loop includes AI — as a tool I build with, and as material I tell stories with.
