EduMation
EduMation is an enterprise-ready education management platform focusing on solving complex scheduling and administrative challenges through automation. The platform centralizes student, teacher, and course management within a multi-tenant architecture, while its core feature — an intelligent, constraint-aware scheduling engine — automates the generation of weekly schedules by integrating internal requirements with external calendar availability (Google, Microsoft, ICS).

THE PROBLEM
Education institutions face a 'scheduling nightmare': manually coordinating dozens of teachers, student groups, and courses across limited time slots while avoiding conflicts with external personal commitments.
Built for professional training organizations managing multiple schools, programs, and student cohorts. The platform needed to handle complex constraint-based scheduling (teacher availability, room capacity, course dependencies) at scale while ensuring strict data isolation between institutions.
- Manual scheduling is brutal. Coordinating dozens of teachers and courses by hand takes days and is error-prone.
- One change breaks everything. A single teacher conflict cascades into dozens of reassignments across the semester.
- No tool exists for this niche. Generic scheduling software can't handle domain-specific education constraints.

THE SOLUTION
from weeks to minutes.
A modular MERN (MongoDB, Express, React, Node) stack with TypeScript for strict type safety. The React frontend follows a custom internal Design System, while the Node.js backend implements a heuristic-driven scheduling service. Each institution's data is isolated via a schoolId-based filtering layer, and external availability is cached with a 180-day TTL index for O(1) conflict checks.

KEY FEATURES
Built around how training organizations & coordinators actually work.
FEATURE 01
AI Scheduling Engine
A heuristic solver that processes hard constraints (teacher availability, room capacity) and soft constraints (lunch breaks, preferences) to generate conflict-free proposals in under 5 minutes.
- Generates 3 distinct proposals using seed-based randomization
- Handles complex multi-cohort timetabling in seconds
FEATURE 02
Real-Time Calendar Sync
Two-way OAuth2 sync with Google Calendar and Microsoft Graph ensures teacher personal commitments are always reflected, with no manual import step.
- 180-day TTL caching for O(1) conflict checks
- Background sync worker handles rate limits gracefully
FEATURE 03
Multi-Tenant Architecture
Strict data isolation enforced at the middleware layer ensures one institution never sees another's data, even on shared infrastructure.
- SchoolId-based filtering on every database query
- Role-based access control per institution and role
TECHNICAL CHALLENGE
Hard problems solved.
The scheduler uses a greedy heuristic that sorts courses by their 'degree of constraint' (Least-Constrained-First). It computes invalid slots by indexing internal events and cached external busy intervals. A seed-based randomization system generates three distinct proposals for administrators, while a dedicated sync worker handles OAuth2-based integrations with external calendar providers.
What made it hard
- Solving the NP-Hard scheduling problem while weighing multiple soft and hard constraints like lunch breaks, working hours, and teacher preferences.
- Ensuring strict multi-tenant data isolation via middleware-level filtering for all database queries across the shared infrastructure.
- Managing high-latency external calendar syncs (Google, Microsoft Graph, ICS) without blocking core application flows or exceeding provider rate limits.
- Building a high-performance interactive schedule UI capable of rendering hundreds of dynamic events with sub-100ms response times for edits.
