Learning Management System
Comprehensive Academic Portal for Students, Courses & Live Classes.
“Unified course management, student enrollments, and interactive live lectures into a single resilient academic portal.”
Replace with high-res UI dashboard screenshot, mockup, or banner (Recommended 1920x1080)
Consolidated Academic Operations Platform
Engineered for an institute requiring an all-in-one ecosystem to manage student admissions, semester course distribution, quiz submissions, and real-time live lecture broadcasts without third-party platform fragmentation.
Project at a Glance
A full-stack learning management system empowering educators to distribute course syllabi, assign homework, record automated attendance, and conduct interactive live lectures.
Educational Technology & Live Classroom Management
Educational Institutes & Academies
Q1 - Q3
Replaced 3 fragmented tools with a single authenticated portal handling course materials, grading, and live lectures.
The Problem
The institute struggled with fragmented software: Moodle for assignments, WhatsApp groups for class announcements, and unmonitored Zoom links for lectures. Students frequently missed live sessions, and professors spent hours manually reconciling attendance records.
Fragmented tools causing student confusion and dropped lecture attendance.
Manual attendance tracking taking 15 minutes of every 60-minute live lecture.
Insecure course material sharing leading to unauthorized syllabus leakage.
No centralized gradebook or academic progress transparency for parents and administration.
Goals
Technical Goals
- Single sign-on academic dashboard unifying course content and live class sessions.
- Automated attendance logging synchronized with live session join/leave timestamps.
- Role-based access control separating Student, Instructor, and Admin privileges.
- Sub-200ms document and lecture recording download speeds.
Business Goals
- Eliminate recurring third-party platform software subscription costs.
- Increase live lecture attendance and student assignment completion rates by >30%.
- Provide administrators with comprehensive audit logs of faculty class delivery.
My Role
Lead Full-Stack Architect
Core Responsibilities
- Designed the PostgreSQL relational schema for courses, enrollments, and lecture schedules.
- Engineered live class integration with WebRTC and Zoom Meeting SDK.
- Built responsive student and faculty dashboards using Next.js and Tailwind CSS.
- Implemented secure S3 document storage with time-limited pre-signed download URLs.
Primary Focus Areas
Solution
We engineered a centralized web-based LMS that bridges synchronous live lecturing with asynchronous course material management. Students log into a single personalized dashboard displaying active courses, upcoming live lectures, and pending assignments.
Integrated Live Classrooms
One-click classroom entry directly within the browser, logging student presence and duration automatically.
Structured Course Modules
Week-by-week curriculum tracking with video recordings, reading PDFs, and submission dropboxes.
Automated Academic Gradebook
Weighted assignment grading, automated quiz evaluations, and exportable transcript reports.
Architecture & Data Flow
Modern multi-tier architecture combining Next.js App Router, Node.js API services, PostgreSQL relational database, and live video streaming gateways.
Authentication & Enrollment
Next.js / JWT AuthStudent logs in; RBAC middleware verifies active semester enrollments.
Curriculum & Media Ingestion
AWS S3 / CloudFrontInstructors upload syllabi and lecture slides to secure S3 storage.
Live Class Room Dispatch
WebRTC / Zoom SDKScheduled class initializes live video room with duplex chat and screen sharing.
Automated Presence Logging
PostgreSQL / RedisSession presence tracker records join duration and syncs with student gradebook.
Core Features
One-Click Live Classrooms
Integrated video roomsLaunch and join live video lectures without leaving the LMS; includes interactive chat and raised-hand queues.
Automated Attendance Engine
Zero manual roll callsTracks student connection duration down to the second, generating instant presence reports for instructors.
Interactive Assignment Dropboxes
Rubric gradingSupports multi-format file uploads, late submission locks, and integrated instructor rubric grading.
Academic Progress Analytics
Visual progress trackingVisual charts tracking student completion percentages, quiz scores, and course engagement over time.
Engineering Decisions
Custom Integrated LMS vs Off-the-shelf Moodle Customization
Why: Moodle's monolithic PHP codebase proved too rigid and heavy for modern mobile-first responsiveness and live socket-driven classroom attendance.
Challenges
Attendance Spoofing: Students opening the live class tab and abandoning it to register attendance.
Implemented periodic client-side active engagement heartbeats paired with visibility API detection.
Guaranteed authentic student participation metrics across all courses.
