I am a South Korea-based frontend developer working on responsive React and Next.js interfaces. I take narrowly defined web tasks: fixing mobile overflow and breakpoint collisions, restoring click targets and interaction states, or building a one-to-five-page brand site with an agreed section and handoff scope. I have delivered two paid OBS/PRISM browser tools with two public 5.0 reviews on a Korean freelance marketplace. They were web-operation tools, not client website builds. LIMEN and my other website studies are independent or self-operated work and are labelled accordingly. I work online, async and text-first with translation-assisted written English. Before starting, I confirm deliverables, acceptance, revision limits, IP and timing in writing and require a funded Twine Vault milestone.…I am a South Korea-based frontend developer working on responsive React and Next.js interfaces.

MORAEVA — Fictional AI-Medical Homepage Interface Concept
MORAEVA is an independently created fictional one-page clinical-interface concept, not client work or a real healthcare service. I designed the information hierarchy, synthetic demo product artifact, responsive frontend in semantic HTML, CSS and JavaScript, mobile navigation, and a non-transmitting briefing dialog. I checked the layout at 320, 390, 1366 and 1440 CSS widths. No patient data, clinical accuracy, diagnosis, partner, certification or business result is represented. webdesign frontend responsive…MORAEVA is an independently created fictional one-page clinical-interface concept, not client work or a real healthcare service.

Responsive UI Repair Method 1/3 — Mobile Overflow
Part 1 of one independent static HTML/CSS/JavaScript reconstruction—not a separate project, client work, client data, paid work, or React runtime evidence. I created controlled broken and fixed states to show a mobile overflow and clipped-CTA failure, then restored responsive content flow and a usable hit target. The complete method was checked in Chromium at 320, 360, 390, 430, 1280 and 1440 CSS pixels.…Part 1 of one independent static HTML/CSS/JavaScript reconstruction—not a separate project, client work, client data, paid work, or React runtime evidence.
