Tech Stack

• Architecture: Turborepo Monorepo, pnpm workspaces
• Admin Portal: Next.js 15, TypeScript, Tailwind CSS

• Backend API: Node.js, Express 5, 18 Route Modules
• Database: Prisma ORM, PostgreSQL (26 Models)
• Queues & Mail: Redis Queue & Nodemailer Worker
• Auth: JWT Auth, bcrypt, 5 User Roles
• Media & Files: Cloudinary, PDFKit (Invoices/Receipts)

Key Accomplishments

• Two-Portal Monorepo Architecture: Designed and built a Turborepo monorepo ERP spanning two independent frontends (29 Next.js admin pages + 20 Vite student pages) unified by a single Express API serving 132 endpoints across 18 route modules.
• Role-Based Access Control: Enforced 40 protected frontend routes using JWT-backed auth context and 5 role-specific middleware guards (admin, professor, student, verifier, and combined) — ensuring zero unauthorized cross-role access.
• Shared Component Library: Extracted 164 shared UI components — dashboards, data tables, multi-filter panels, form builders, and navigation primitives — enabling consistent UX across both portals with zero duplication.
• Scalable Relational Schema: Architected a Prisma database with 26 models, 32 enums, and 89 relation fields covering users, applications, enrollments, payments, grades, attendance, and complaints — optimized for complex cross-entity queries.
• Asynchronous Email Worker: Built an async email worker using Redis queues and Nodemailer — 7 purpose-built templates, 3 priority queues, and automatic retry (3 attempts) for admission confirmations, payment receipts, and placement notifications.
