12-Week Intensive Curriculum

Transform from beginner to professional

Month 1

Core OOP Principles & JavaScript Fundamentals

Goal: Solidify understanding of the four pillars of OOP and master JavaScript syntax as the foundation for Node.js.

Learning Objectives:

  • Define and explain Encapsulation, Inheritance, Polymorphism, and Abstraction.
  • Master JavaScript data types, functions, scope, and ES6+ features.
  • Implement OOP concepts using JavaScript's prototype and class syntax.

Key Tools & Technologies:

JavaScript (ES6+) Node.js Runtime VS Code Git & GitHub

Weekly Breakdown:

Week 1-2: JavaScript for OOP
  • Advanced Functions & Closures
  • The 'this' keyword and binding
  • Prototypes and the Prototype Chain
Week 3-4: Implementing OOP Pillars
  • Classes, Constructors, and Methods
  • Inheritance with 'extends' and 'super'
  • Polymorphism via Method Overriding
  • Abstraction using Modules and Interfaces

Hands-On Project:

Library Management System CLI
  • Deliverable: A command-line application using Classes to manage books, users, and checkouts, demonstrating encapsulation and inheritance.
Month 2

Node.js Ecosystem & Building Scalable OOP Architecture

Goal: Apply OOP principles to build modular, maintainable, and scalable server-side applications with Node.js.

Learning Objectives:

  • Structure a Node.js project using OOP design patterns.
  • Build RESTful APIs with Express.js using Service and Controller layers.
  • Implement data persistence with MongoDB and Mongoose ODM.

Key Tools & Technologies:

Express.js MongoDB & Mongoose Postman Design Patterns

Weekly Breakdown:

Week 5-6: Node.js Fundamentals & Express
  • Modules (CommonJS vs ES Modules)
  • Event Loop and Async Programming
  • Building a layered Express architecture (Router, Controller, Service)
Week 7-8: Data Modeling & OOP Patterns
  • Mongoose Schemas and Models as Classes
  • Implementing Repository Pattern for data access
  • Applying Singleton, Factory, and Dependency Injection patterns

Hands-On Project:

E-Commerce Backend API
  • Deliverable: A fully-featured REST API for products, carts, and orders, using Models, Services, and Controllers to enforce abstraction and separation of concerns.
Month 3

Advanced Concepts, Testing & Deployment

Goal: Master advanced OOP patterns, ensure code quality with testing, and deploy a production-ready Node.js application.

Learning Objectives:

  • Implement advanced design patterns (Observer, Strategy, Middleware as Chain of Responsibility).
  • Write unit and integration tests for OOP code using Jest.
  • Containerize and deploy the application to a cloud platform.

Key Tools & Technologies:

Jest Docker AWS / Render Advanced Design Patterns

Weekly Breakdown:

Week 9-10: Testing & Code Quality
  • Writing testable OOP code
  • Mocking Dependencies and Testing Classes
  • Test-Driven Development (TDD) workflow
Week 11-12: Advanced Patterns & Deployment
  • Implementing messaging and event-driven architecture
  • Dockerizing the Node.js application
  • CI/CD pipeline basics and deployment to cloud

Hands-On Project:

Real-Time Task Management System
  • Deliverable: A full-stack application with a React frontend and a Node.js backend using Socket.io. The backend will be a showcase of advanced OOP architecture, comprehensive testing, and containerized deployment.

Real-World Projects

Build a portfolio that proves your skills

E-Commerce Backend API

Architect a scalable REST API for an online store. Implement product catalog, user authentication, shopping cart, and order processing using OOP principles, Mongoose models, and the Repository pattern.

Microservices Communication System

Build two independent Node.js services (e.g., User Service & Notification Service) that communicate via REST and message queues. Demonstrates abstraction, loose coupling, and the Observer pattern.

Real-Time Collaborative Dashboard

Develop a dashboard with live updates using Socket.io. The backend will use advanced class hierarchies and polymorphism to manage different types of real-time data streams and client connections.

Who Is This For?

JavaScript Developers

Frontend or basic JS developers who want to deeply understand OOP and transition to senior backend or full-stack roles using Node.js.

CS Graduates & Freshers

Graduates who know OOP theory but lack practical experience applying it in modern backend development to become job-ready.

Career Switchers

Professionals from other fields aiming to break into high-growth tech with a structured, project-based path to becoming a Node.js developer.

Self-Taught Programmers

Coders with gaps in their foundational knowledge who need to systematize their understanding of OOP and build scalable applications correctly.

GOT QUESTIONS?

Frequently Asked Questions

Real questions from our community, answered by our experts

What is the "object oriented language definition" in this course context?

+

In this Node.js certification program, we define and teach Object-Oriented Programming (OOP) as a programming paradigm based on the concept of "objects", which contain data (attributes) and code (methods). We focus on the four core pillars—Encapsulation, Inheritance, Polymorphism, and Abstraction—and show you how to implement them practically in JavaScript and Node.js to write clean, modular, and scalable backend code.

Do I need prior Node.js experience?

+

No. The course starts with JavaScript fundamentals essential for OOP. However, basic programming knowledge (variables, loops, functions) in any language is required. We build your Node.js skills from the ground up.

How is this different from other Node.js courses?

+

Most courses teach Node.js syntax and frameworks. We teach you how to architect software. The core differentiator is our deep focus on applying solid Object-Oriented Language principles to design professional, maintainable, and testable backend systems, not just making APIs work.

What does the "100% Job Support" include?

+

It includes resume and LinkedIn profile review tailored for Node.js/Backend roles, mock technical interviews focusing on OOP and system design, access to our exclusive job portal, and direct referral opportunities to our hiring partner network until you secure a position.

Will I get a certificate?

+

Yes, upon successful completion of all projects and course assessments, you will receive a verifiable "Node.js & OOP Certification" from Lead With Skills. However, your main credential will be the 6-project portfolio you build.

What is the time commitment per week?

+

We recommend 12-15 hours per week. This includes 4-6 hours of live sessions/mentorship and 8-9 hours of self-paced project work, practice, and assignments.

Is the fee one-time or monthly?

+

The total program fee of ₹18,999 INR / $224 USD is a one-time payment. We do not have hidden charges or monthly subscriptions. It covers all 12 weeks of training, mentorship, projects, and job support.

Can I learn if I'm from a non-CS background?

+

Absolutely. We've designed the curriculum to build concepts from the ground up. The focus on practical projects helps non-CS learners grasp abstract OOP concepts by applying them immediately. Our 1:1 mentorship is crucial for addressing individual doubts.

What software/tools do I need?

+

A computer (Windows, macOS, or Linux), a stable internet connection, and a code editor (we recommend VS Code). We will guide you through installing Node.js, MongoDB, Git, Docker, and all other necessary free tools and accounts in the first week.

What if I miss a live session?

+

All live sessions are recorded and available in your student dashboard within 24 hours. You can review them at your convenience and discuss any questions in the next mentorship call or our dedicated community channel.
