Ruang Bimbel Indonesia

I solo-built ruangbimbel.id from zero to production — an online learning platform that helps users prepare for CPNS, BUMN, and UTBK exams through complete study materials, question banks, and realistic simulations. It's an all-in-one space for learning, practice, and evaluation, where users can take tryouts that feel just like the real test — complete with scores, detailed discussions, and personalized insights.

Frontend — Built with Next.js, TypeScript, and TanStack Query for a fast, type-safe, and seamless UX across 4 separate applications:

• 🌐 Landing App — Public-facing marketing & information site
• 👤 User App — Main learning platform
• 🛠️ Admin App — Content management based admin role
• 👑 Super Admin App — System administration & analytics

Backend — Powered by Go with Gin framework, PostgreSQL, and Redis for reliability, speed, and smart caching — all containerized with Docker.
