Modular website design for an in-house green tea campaign, aimed at streamlining invoice-based promotional sites.

To meet the increasing demand from advertisers for invoice-based promotional campaigns, our team initiated the creation of a modular invoice registration website. This internal project began with a fictional campaign — “Buy Refreshing Green Tea, Win Big” — to prototype the system’s visual and functional structure. I took the lead on designing a fictional green tea product, its promotional key visual, and the full responsive website layout to demonstrate the system’s flexibility and appeal.

My role was to anticipate common client needs and translate them into reusable web sections: a campaign banner, invoice upload module, and activity guidelines. To enhance workflow efficiency, I created a ready-to-use Figma template and worked closely with our front-end developer to define standardized specs and responsive behaviors. I also prepared visual guidelines and internal onboarding decks, enabling even non-design stakeholders like PMs to easily assemble campaign pages. The goal was to simplify production to a near plug-and-play level — where designers could simply copy and adapt components.
