Novademi

01 — Problem

The institute's courses, coaching and events ran on a Laravel monolith held together by demo screens. There were no real tables for orders, enrollments, certificates or coaching; student progress and coach follow-up were tracked by hand.

02 — System

We rebuilt it as a tested TypeScript modular monolith and two Next.js apps. The browser never touches the API: sessions live in httpOnly cookies and requests travel server-to-server through a server-side layer. Legacy users migrate on first login, with old password hashes verified and upgraded to stronger ones.

03 — Architecture

Site and admin apps reach the API through their own server-side layers. Payment and notification jobs are processed from database queues by a separate background worker.

04 — Capabilities

1. 01

   Identity and security

   Four login audiences, 15-minute access tokens, rotating refresh tokens with reuse detection, mandatory TOTP for admins and an 11-role / ~40-permission catalogue.

2. 02

   LMS core

   Course → section → lesson structure, sequential unlocking, server-side completion, resume position, lesson notes; a drag-and-drop curriculum builder.

3. 03

   Classes and live lessons

   Class-specific live lessons, present/late/absent/excused attendance, automatic meeting creation and sync through the video-conferencing integration.

4. 04

   Exams and assignments

   Section, final and practice quizzes; single/multiple choice, true-false and open questions, server-side timers, autosave and a grading queue.

5. 05

   Coaching

   Capacity-aware coach–student matching, weekly availability, 14-day booking without double-booking, sessions drawn from package quota and daily study plans.

6. 06

   Practice exams and topic analysis

   Automatic net-score calculation for TYT/AYT/YDT/LGS practice exams; net trend, per-subject change and the topics that cost the most over the last 10 exams.

7. 07

   Commerce and access

   Orders with idempotency keys and an explicit state machine, virtual-POS payments and a signed webhook, discount codes, per-item partial refunds; payment turns into course access automatically.

8. 08

   Certificates and tickets

   PDF certificates generated without a library, public verification and revocation notices; 256-bit-token digital tickets with a validation page for events.

05 — Impact

• 01

  Coaching, courses, exams, certificates and events now live under one member account.

• 02

  Legacy users move to the new system without resetting their passwords.

• 03

  Coaches see each student's exam trend and weak topics without manual calculation.
