kimbsoo
About this gig
I build fast custom websites with React and Next.js. No page builders, no bloated templates, no plugin subscriptions. Just clean code that loads quickly and works on every screen. What you get - A site built from scratch in React / Next.js - Fully responsive, mobile first - Speed optimized and SEO ready - Deployed live and working, not handed over as a folder of files I run my own web services in production, including a sports media platform and a Steam deal tracker with live data pipelines. So I build for what happens after launch, not just for handoff day. I also work with Korean platform APIs, including public data, Coupang, Naver Smart Store and Toss. If you are bringing a product into the Korean market, I can handle the integration and localization side too. Message me before you order. Tell me what you need and I will tell you honestly whether it fits a package or needs a custom offer. I would rather turn a project down than miss your deadline. Based in South Korea (KST). I reply within a few hours.

I build and operate live consumer web services in Korea — a sports
media platform, a Steam deal tracker, and several mini-apps on Toss,
Korea's largest fintech super-app with 30M users.
My specialty is the part of a Korean launch that outside teams can't
do on their own: Korean public data APIs, marketplace APIs (Coupang,
Naver Smart Store), Toss platform integration, and localization.
Stack: React, TypeScript, Next.js, Astro, Java/Spring Boot,
PostgreSQL, Cloudflare Workers.
Tell me what you need built — I reply within a few hours (KST).

FAQ
Do you use WordPress or a page builder?
No. Everything is hand coded in React and Next.js. That means faster load times, no plugin bloat, and no monthly fees for a builder you do not control. You own the code.
What do you need from me to get started?
Your text and images, any brand colors or reference sites you like, and a rough list of the pages you want. If your content is not ready yet, I can build with placeholders and swap it in later.
Will I be able to edit the site myself later?
By default the content lives in the code, so edits come through me. If you want to update pages yourself, message me before ordering and I will add a simple CMS as a custom offer.
Can you work with Korean platforms and APIs?
Yes. I work with Korean public data APIs, Coupang and Naver Smart Store APIs, and the Toss mini app platform. Send me the details and I will quote it as a custom offer.
Do you provide hosting and a domain?
Hosting setup is included in Premium and available as an extra on the other packages. The accounts stay in your name and you keep full ownership. I only configure them for you.
