I build the product and the story around it.
I'm Eric (Hyunjun Kim), studying Marketing & Information Systems at HKUST. I start with who a product is for, what it needs to do and why someone would choose it.
On my independent projects, I carry that thinking from research and positioning into product planning, interface design, frontend and backend development, testing and product marketing. I plan the work, build the experience and shape how it reaches people.
I also contribute to language-learning software with HKUST's Center for Language Education. XiYouQuest, a team project I contribute to, won 1st Place at the 2026 HKUST GenAI Hackathon.

I research before committing to a direction, review the full brief and make the proposed experience visible before building. I check the result against its purpose, refine it through feedback and keep useful decisions in a linked knowledge base.
ChatGPT supports research, planning and building; Claude helps refine the design details and finish the work. I set the direction, coordinate the process and review the results.
