Designing five live websites in four months.

I joined Build-One, part of the Daedong F·E group, as its first marketing hire. The existing brand and website needed a clearer presentation, better mobile layouts, and a consistent way to introduce the company’s materials. The audiences included architects, construction purchasing teams, and contractors.

Within a four-month internship, the work extended from visual identity to five corporate and product websites. The challenge was to connect these touchpoints while giving each product a clear place in the wider group.

I refreshed the Daedong F·E and Build-One logos and wrote their usage rules. I also designed Daedong F·E’s business cards and drafted the group’s first marketing roadmap. Establishing these elements together gave the website work a consistent visual starting point.

In Figma, I developed user flows, responsive layouts, and a shared component library for the Daedong F·E and Build-One / Long Brick sites. Reusing components helped carry the design direction across related pages while leaving room for product-specific information.

I designed the Daedong F·E and Build-One / Long Brick website flows and layouts in Figma. The product-page work organized browsing, specifications, colour options, and inquiry steps around the information a visitor needs before contacting the company.

I carried these decisions through responsive layouts and a shared component library. The screens below show the Figma proposal alongside the live implementation, including refinements made during collaboration.

For Thin Ceramic, Modular Stone, and SE Fastener, I built the front end directly in the company’s React, TypeScript, and Tailwind CSS codebase. I worked through each page day to day with the CEO and engineering director.

This required making design decisions within the implementation: translating product information into responsive pages, adapting to feedback, and keeping the sites visually connected. The five-site delivery combined Figma-led work with three sites developed directly alongside the engineering team.

My contribution covered visual identity, website flows and layouts, a shared component library, and front-end implementation. The engineering director provided technical guidance and implementation refinements. Multilingual and SEO setup were outside my contribution. I used Claude and Codex as coding assistants within this collaborative workflow.

I also worked with a Daedong F·E engineer on an AI system for automating construction drawings and was named as an inventor on the patent application, which is pending.

For the company’s product communication, I produced four YouTube Shorts from AutoCAD 3D models using AI video tools and refreshed the profiles of its existing Facebook, Instagram, and YouTube channels.

All five company websites went live within four months. The work also delivered refreshed logos and usage rules, business cards, a first marketing roadmap, four YouTube Shorts, and updated social-channel profiles.

Working across design and code taught me to turn a visual direction into reusable interface decisions and to resolve implementation questions with the engineering team. The result I can demonstrate is the delivered work and my contribution to it; this case does not claim a measured increase in conversion or usability.
