Technology another team can take over.
We consider developer availability in Korea, predictable operating costs and whether another team can take over.
Web frontend
React, Next.js, TypeScript, Tailwind CSS, shadcn/ui
We build landing pages and admin interfaces, configure page titles and descriptions for search, and check layouts and loading performance across devices.
Mobile apps
React Native, Expo, EAS, Native Modules
We share code across iOS and Android while handling platform-specific behavior separately. Native modules are used where direct device control is needed.
Backend and data
Node.js, Supabase, PostgreSQL, Prisma
We store user and business data and control access and changes by permission. Database design considers expected data volume and user numbers.
Deployment and operations
Vercel, GitHub Actions, EAS Build, Sentry, PostHog
We automate builds and deployments and collect error and usage data, making release history and affected versions traceable.
AI
OpenAI API, Vercel AI SDK, RAG, Evaluation datasets
We show the documents an AI answer is based on and require staff approval of generated responses. Real questions and expected answers are used to check accuracy.
Three questions behind our technology choices
After checking that a technology meets the functional requirements, we review the following.
Can you find developers for it?
We consider whether your team or another provider can find the developers needed for handover, and whether documentation and community support are available.
Is it suitable for production?
We review production use, support lifecycles and known issues, then select versions compatible with the other libraries in your system.
What does it cost to build and maintain?
We compare development and infrastructure costs, along with the work required for updates and incident response, to propose an approach suited to your budget and team.
