Project details

I build fast, custom-coded websites that get found in both search engines and AI answers.

Most agencies stop at "it looks nice." I go further: every site ships with clean semantic markup, per-page meta tags, OG images, an auto-generated sitemap, and JSON-LD structured data so your pages can be cited by Google and by AI assistants like ChatGPT and Perplexity.

What you get:
 • Responsive design that holds up on desktop, tablet and mobile
 • Server-side rendering for fast loads and better indexing
 • SEO and GEO structure built in from day one, not bolted on later
 • Multilingual routing if you need Korean/English or other locales
 • Full source code, so you are never locked into one vendor

I have built and deployed brand sites, global platforms and corporate sites end to end - planning, design, front end, back end and deployment - so there is one owner and no handoff gaps. Stack: Next.js/React, Node, TypeScript.

About Chunghun

Chunghun L.Status: Offline
EnterNext. One team for strategy, design, dev, marketing, and AI.
Seoul, South Korea - 7:16 am local time
I build the systems companies actually run on: commerce platforms, internal admin tools, ERP/CRM dashboards, and data automation.

Recent work includes a B2B wholesale marketplace built from scratch (multi-role suppliers/sellers, order pipeline, settlement dashboard), an ERP for an import distributor covering purchase orders through settlement, an AI-assisted product detail-page generator for a fashion store, and scrapers that turn hours of daily manual work into a few clicks - 4,452 apartment units collected in about a minute.

I run projects end to end - planning, design, front end, back end, deployment - so there is one owner and no handoff gaps. Stack: Next.js/React, Node, Python, PostgreSQL, with OpenAI and third-party API integrations. I also handle SEO/GEO so what I build actually gets found.

If you have a manual process, a spreadsheet workflow, or an idea that needs to become a working product, I'd rather show you a demo than a deck.
