The parts clients don't see until they're missing

  • Design and build, one hand

    I sketch the page and write the code, so what you approve is what ships. Responsive at 1440 / 1280 / 834 / 390 widths, with reduced-motion and keyboard support.

  • Inquiry flow that works

    Server-validated lead forms with field-level errors and a spam honeypot. Accessible menus, dialogs, and accordions by default.

  • Launch and handoff

    Metadata, OG images, sitemap, and JSON-LD wired on every page. Deployed on Vercel with your domain, or a clean repo handoff with a README.

  • All of it, standard on every build

I'm Gyeongbin, a computer science student in Seoul. I sketch the page and write the code, so what you approve is what ships.

Brief to launch in four steps

The Growth and Custom arc below. The Launch package compresses the same arc into 5 days because you bring the copy and the direction.

  1. 01Day 0

    Brief

    A 20-minute async brief: your product, audience, the one action the page exists to drive. I reply with questions and a fixed quote.

  2. 02Day 1-3

    Design concept

    One hero-direction concept plus section plan. You approve the direction before a single full section is built.

  3. 03Day 3-7

    Build

    Full responsive build with real copy, motion, and form logic. You get a live preview URL from day one.

  4. 04Day 7-10

    QA + launch

    Cross-viewport QA, accessibility pass, SEO check, then deploy to your domain. Revision rounds happen here.

  • Four of the showcased projects are self-directed concept work. Their brands are fictional and disclosed as such on each site. Plugview is a live product build, while JellyPal is a shipped Windows desktop-pet mini project. All are held to the same standard: real responsive QA, accessibility, SEO, and interaction details. The point is to show the range of products and design systems I can build, end to end.
