Kohyun L.
Over deze dienst
I turn a business idea, or a messy spreadsheet-and-chat workflow, into a SaaS that people actually use - user app, admin panel, data and integrations in one flow.
Products I built and still run
- DongdaemunClick - GPT-powered e-commerce product listing automation
- ManualQ - AI safety-training SaaS with assignments and certificates
- Shopilgong Solution+ - ad profit analytics combining ad spend, cost and refunds
What I build
- Sign-in, roles and permissions
- PostgreSQL / Supabase data model and admin tools
- Stripe billing, email and Slack alerts, OpenAI features, REST APIs
- Responsive UI, deployment on Vercel, error tracking
Stack: Next.js, React, TypeScript, Supabase, Vercel. You see working results every 1-2 weeks and the source code is yours. Please message me before ordering Standard or Premium so we can confirm scope.

Talen
Koreaans, Engels
I'm Kohyun, an independent product builder in Seoul. I design, build and launch apps end to end - product scope, UX/UI, React Native and Expo, Next.js and Supabase, App Store release and the updates after it. I run 9 live iOS/Android apps of my own, shipped in 175 countries and localized into up to 15 languages, plus 3 SaaS and automation products. When you work with me you get one person who owns the whole thing, clear scope before we start, and real builds you can tap every week or two.
Veelgestelde vragen
Can you migrate our spreadsheets or existing data?
Yes. I review the format and volume first, then plan cleanup, deduplication and validation as a separate, clearly priced step.
Who owns the code and hosting accounts?
You do. Everything runs on your own Vercel, Supabase and Stripe accounts, and you get the full source code plus a list of environment variables and setup notes.
