GuruLink.
Full-stack multi-tenant SaaS platform for tuition institutes and tutors. It connects public marketplace discovery with tenant dashboards for students, classes, QR/code attendance, fee collection, monthly ledgers, inquiries, community posts, subscriptions, and super-admin billing controls.
Next.js 16, React 19, TypeScript, and Tailwind CSS on the front; Express.js, Prisma ORM, PostgreSQL, JWT, tenant middleware, role middleware, subscription middleware, Zod validation, and Vercel Blob uploads on the back. A pnpm monorepo keeps frontend, server, shared packages, and infrastructure assets together.
Problem
Tuition institutes often split student records, attendance, payments, public marketing, inquiries, and parent communication across spreadsheets, chat groups, receipt books, and disconnected tools. That makes fee reconciliation slow and creates operational gaps between admissions, tutors, and finance teams.
Solution
GuruLink connects the public discovery journey to the internal operating system of a tuition business. Parents and students can discover classes and submit inquiries, while tenant teams manage classes, enrollments, QR/code attendance, monthly fee ledgers, outstanding balances, subscriptions, and community announcements from one dashboard.
