Full-stack web application development
We build web apps that are fast, beautiful, and built to scale
Web application development is the practice of building high-performance web applications on a modern full stack — Next.js, TypeScript, and Supabase. TreeSoop delivers everything from startup MVPs to large-scale SaaS platforms, with quality proven by a 4.92/5 rating on Wishket, Korea’s largest dev-outsourcing platform, built by a team of KAIST and POSTECH engineers.
A legacy codebase weighed down by technical debt — or an inefficient development process — keeps delaying feature launches while the same bugs come back again and again.
More than 60% of all traffic comes from mobile, yet the existing service is slow and awkward on phones — and bounce rates stay high.
When a marketing campaign or event sends traffic surging, the servers crash — and the outage turns directly into lost revenue.
React Server Components, streaming rendering, and static generation on the latest Next.js architecture deliver best-in-class performance and SEO at the same time.
The Vercel Edge Network guarantees sub-100ms response times anywhere in the world, on serverless infrastructure that scales automatically when traffic spikes.
TypeScript strict mode plus Vitest and Playwright E2E tests prevent runtime errors and keep the codebase stable.
PostgreSQL-based Supabase stands up authentication, realtime database, and file storage fast — cutting backend development time by 50%.
We define business goals, user journeys, and core features, then validate them together with wireframes.
We produce high-fidelity mockups in Figma and iterate on your feedback.
Features ship incrementally in two-week sprints, with a demo shared at the end of every sprint.
Automated testing, Lighthouse performance scores of 90+, and cross-browser verification.
CI/CD pipeline setup, monitoring configuration, and operations training complete a stable handover.
