Web Application Development in Surabaya

Browser applications and the APIs behind them, from interactive front ends to data-heavy tools.

The front end is built with Vue 3 and Quasar or with Next.js and React, depending on what the project needs: Quasar when a dense, component-rich interface matters, Next.js when server rendering and public discoverability do. Back ends are Node.js with Express, or Go when the service has to be small, fast and easy to deploy as one binary.

Two public projects show the range. Job Wire combines several job sources behind one Express API, with optional Redis caching and an in-memory fallback, and ranks results against a CV parsed from PDF or DOCX. Workspace Designer is a 3D house designer in Next.js with Three.js and Tailwind CSS where state changes drive the 3D scene and a running price.

What you receive

  • Responsive interface tested on phone, tablet and desktop widths
  • A documented HTTP API with input validation and consistent error responses
  • Server-side or build-time rendering for pages that need to be indexed
  • Deployment configuration for Vercel or a Node process behind a reverse proxy
