📘 UDEMY COURSES BY PRASHANT SHARMA

I create beginner-friendly and practical courses for developers who want to grow in Java, backend development, Spring Boot, and real-world project skills.

Each course is designed with clarity, simplicity, and real-world examples that make learning easier.

🔥 1. MongoDB + Spring Boot CRUD Application for Beginners

Do you want to learn how to connect Spring Boot with MongoDB to build powerful and scalable backend applications? This course — MongoDB with Spring Boot CRUD Application from Scratch — is designed to take you step by step through building real-world CRUD (Create, Read, Update, Delete) operations using Spring Data MongoDB.

You’ll start with a simple overview of MongoDB, understanding collections, documents, and NoSQL data modeling. Then, you’ll learn how to integrate it with Spring Boot to build a fully functional RESTful API from scratch, focusing on best coding practices and clean architecture.

Throughout the course, you’ll gain hands-on experience with key backend development concepts, including repository patterns, service layers, exception handling, and REST endpoints. You’ll also explore querying, sorting, pagination, and working with MongoRepository interfaces for efficient data access, along with performance tuning and error management strategies.

By the end of this course, you’ll be confident in developing, testing, and deploying modern Java backend applicationsusing Spring Boot and MongoDB — ready for production or integration into microservices architecture and cloud-based environments like AWS or Azure.

Whether you’re a Java developer, backend engineer, or student eager to learn Spring Boot development, this course provides the practical skills, in-depth understanding, and real-world examples you need to build, secure, and scale professional-grade applications confidently.

Join today and start mastering Spring Boot with MongoDB — one of the most in-demand combinations for modern full-stack and backend development.

Perfect for:

  • Students

  • Freshers

  • Developers switching to Java

🔥 2. Master Keycloak with SpringBoot: Secure Java Apps Like a Pro

Do you want to master modern application security and protect your Java/Spring Boot applications like a pro? This course will teach you everything you need to know about Keycloak, the most popular open-source Identity and Access Management (IAM) solution.

In this hands-on course, you’ll start by learning the fundamentals of Keycloak—realms, clients, users, roles, and groups. Then, you’ll integrate Keycloak with Spring Boot applications to secure REST APIs, web apps, and microservices. Along the way, you’ll gain practical knowledge of OAuth2, OpenID Connect (OIDC), JWT tokens, and Spring Security, all while applying them in real-world projects.

Here’s what you’ll learn in this course:

  • Keycloak basics: setup, configuration, and core concepts.

  • Integrating Keycloak with Spring Boot & Spring Security.

  • Securing REST APIs with OAuth2 and JWT tokens.

  • Implementing role-based and fine-grained access control.

  • Enabling Single Sign-On (SSO) and identity federation.

  • Best practices for securing enterprise and microservice applications.

No prior Keycloak experience is required! A basic understanding of Java and Spring Boot will help you follow along.

By the end of this course, you’ll be confident in building secure applications with Keycloak and Spring Boot, making you highly valuable in today’s job market where application security, SSO, and microservice protection are in demand.

Take this course today and become a Keycloak + Spring Boot security expert!

🔥 3. Must Java Developer Interview Questions And Answers

Are you preparing for your next Java developer interview and feeling a bit unsure about the kinds of questions you might face? Don’t worry — you’re not alone! Whether you're a fresher stepping into your very first interview or an experienced developer looking to take the next big leap in your career, this course is your ultimate companion to help you crack Java interviews with clarity and confidence.

In "Must Java Developer Interview Questions and Answers," we’ve handpicked and curated the most frequently asked and important interview questions based on real-world interviews from top tech companies like Infosys, TCS, Accenture, and more. Each question is carefully broken down with clear, detailed explanations, coding examples, and real-life scenarios so that you're not just memorising answers — you’re truly understanding the concepts and learning how to apply them in real interview settings.

We’ll cover everything from Java basics to advanced topics like OOPs, Collections, Multithreading, Java 8 features, Exception Handling, and even tricky logic-based questions that often stump candidates. Plus, you’ll get bonus tips on give interviews with confidence if you opt for mock interviews that I conduct free of charge.

🔥 4. Build Microservices with Spring Boot, REST & MySQL

As we all know MicroServices is a scorching topic these days and there are a lot of job openings in this field too and so does the competition. You will see a lot of courses on Udemy where everyone has nicely explained what MicroServices is and how it helps a developer, which may help you crack the technical interview while job hunting.

But, after you get into the organization, you have to be ready to code which you will only gain after doing a lot of practicals on MicroServices. So, here I am with one of the best real-time applications to get you ready to have some exposure to the real technical world.

In this course, we are going to create 4 MicroServices applications from scratch using Spring Boot, REST, and MySQL. All these microservices will be communicating with each other.

  1. Movie MicroService

  2. Genre MicroService

  3. API Gateway

  4. Service Discovery

Here, we will have two main microservices which will impersonate a very basic example of IMDB app/website.

  1. Movie MicroService

  2. Genre MicroService

These two services will have their own database and both these microservices will be communicating with each other to get the data.

This course will really help you to gain exposure to what real-time applications look like.

🔥 5. CRUD app using Spring Boot + JPA + PostgreSQL + Thymeleaf

Spring Boot is a really hot topic these days and there are a lot of job openings in this field too and so does the competition. You will see a lot of courses on Udemy where everyone has nicely explained what Spring Boot is and how it helps a developer which maybe can help you crack the technical interview while job hunting.

But, after you get into the organization, you have to be ready to code which you will only gain after doing a lot of practicals on Spring Boot, So, here I am with one of the best real-time applications to get make you ready enough to have some exposure to the real technical world.

In this course, we are going to create a CRUD application from scratch using Spring Boot, JPA, Hibernate, Thymeleaf, and PostgreSQL.

CRUD application means to CREATE, READ, UPDATE, and DELETE.

Here, I've taken a reference for the WORKFORCE MANAGEMENT application which is basically used to manage resources. This application is always used in organizations to manage employees. Some features of this application:

  • Add a new employee to the application

  • New/Existing users can add/edit personal information or skillset information by adding new skills to it.

  • Depending on the skill set of an employee, allocate an employee to a project or allocate some percentage of the employee's work to a project

  • Remove an employee from the application

    ... and so on...

So, I've taken an example of the above application which I also made from scratch in one of the previous organizations. Hence, in this course, I'm trying to showcase a mini version of the above-explained application which is to:

  • CREATE EMPLOYEES

  • DELETE EMPLOYEES

  • UPDATE EMPLOYEES

  • VIEW EMPLOYEES

This course will really help you to gain exposure to what real-time applications look like.
